Growing Astilbe – False Spirea Plant- How to Grow and Care for Astilbe

Try growing astilbe for beautiful, showy flowers that do well in a shady garden bed. This perennial has feathery flowers that sit above the fern like foliage in a majestic way. These tips will show you how to grow astilbe and bring color to your shady perennial garden beds.Astilbe is a showy perennial plant that does well and flowers in a shady garden spot.

Most shady garden beds are filled with ferns and hostas. While these plants are lovely in themselves, it’s still nice to have a plant which will actually flower well in very little direct sun. Astilbe is one of those plants.

My mother had a lovely garden set up until she died.  Once she retired and had time to spend in the garden, she became an expert at making them really beautiful.

Most of her beds were in full sun but she had a long raised planter along one side of her house that was in part shade most of the day.

To give a pop of color in this shady spot she chose to grow astilbe.  And grow well, they did! I loved seeing their pretty blooms every time I walked by the garden spot.

I visited her a few years ago and she gave me some divisions of astilbe to bring back to North Carolina for my garden (she lived in Maine.)  They survived the trip back and are growing well and increasing in size each year.

Astilbe loves the cooler weather.  Cooler climates like the Northeast are idea for using astilbe as a border plant. This photo was taken in the Boothbay Botanical Gardens in Maine and shows how pretty and lush astilbe grows there as a companion to irises.astilbe in a border with bulbs in Boothbay Botanical Gardens

Tip for Growing AstilbeImages of astilbe

Astilbe is easy to grow, and is very tough and hardy.  One of the beauties of them is that they do equally well in part sun or partial shade and will flower in either location. They prefer shade to look best.

The prettiest thing about astilbe is their canopy of tall flower stalks about a glossy green leaf structure. And one can easily see where it got the common names like “false goats beard” or “goats beard plant.” Pink goats beard flowers

Caring for astilbe is easy if you follow these tips:

Astilbe growing conditions are mainly focused on making sure that the plant gets enough water and not too much sunlight.  Here are some general growing tips.Astilbe is a flowering shade loving perennial

Sunlight Needs for Astilbe

Planting astilbe is best done in a bed that is either in half sun/half shade or in full shade with just filtered light. I have mine growing in garden beds that are facing north and they get a bit of late afternoon sun. This seems to suit them beautifully.

If you live in a cool northern climate, astilbe can take full sunlight, but for the rest of the US, it does prefer some shade.

Astilbe Flowers

The most commonly grown astilbe have flowers that are in the red/pink variety with colors ranging from dusty pink through to vibrant pinks and reds. 

Some varieties of astilbe are also pale tan or even white. Check out this post for some great images of astilbe colors.

Some astilbe flowers are fine and feathery and others have the goats beard flower shape and texture that is much firmer and more plump.Colors of astilbe perennials

Astilbe is considered non-toxic to pets.

Why is my astilbe plant turning brown?

Astilbe like a soil that is very rich and well draining and also likes moisture.  If you let the soil dry out too much, the plant will start to turn brown.

When you water astilbe, make sure that the water soaks down deeply to the roots to ecourage them to root deeply . Deep rooted plants benefit from the even moisture that is lower than that at soil level.

Astilbe plants also can turn brown as a result of too much sunlight.

How large does astilbe grow?

Most will grow to about 36″ tall with the flower stalk and about 2 feet wide.  But there are also varieties that will grow to 5 feet so be sure to choose one suited to the space you have.

You can plant astilbe fairly closely together if you want a cluster like look.  For individual plants space them 1-3 feet apart depending on the variety.

When does False spirea bloom?

The leafy green party of the plant grows steadily all spring and then about mid to late summer it is astilbe bloom time, when the long flower plumes will open up above the plant.

This can vary for different types of plants, though.  Astilbe will not flower for the whole of the summer. 

Some plants bloom in late spring and others in mid-summer or late summer. Most plants will give a show in the latter part of the summer.

Plants grown completely in the shade will not give quite as good a display of flowers but dappled shade will give a good flower show.

Should I deadhead astilbe?

Deadheading is done to encourage new blooms on a plant. Since this task won’t push your astilbe into putting out more blooms, it is not necessary. (See other plants that don’t need deadheading here.)

Leaving the spent blooms in place through the fall encourages birds to feed which is always nice to see in a garden. Eventually the flowers will dry. I leave my seed heads right into the winter for the birds and then just trim them up in early spring.

Eventually the flowers on the plant will dry in place.

Companion Plants to grow with Astilbe

When choosing Companion plants  for goats beard perennial, select perennials and bulbs that have similar growing habits.  Once you find a spot where one will do well, they all benefit.

Ferns, and hostas are good choices, as are many other shade loving plants such as coral bells. See my list of good companion plants for Astilbe.

How to propagate astilbe

Growing astilbe from seed is possible but this can be a challenge. The normal way to propagate astilbe is from root divisions.

Astilbe will send out more and more plants as it matures.  Dividing astilbe is just a matter of digging up the plant and separating some of the smaller babies to get more plants for free.astilbe plants

They take quite easily as is evidenced by mine in their two day car ride in the middle of summer.  Advisable to plant in the early spring or fall.  Divide astilbe every two to three years.

If you have a plant that was originally placed in the wrong part of the garden, you can move it to another spot where it will get the best light conditions. Transplanting astilbe is best done in the early spring or fall months when the temperatures are cooler.

Watering needs for astilbe

Astilbe likes moist soil so hotter climates will need to have them in shade and you’ll need to add extra water.  They grow best in Northern areas where it is cool and wet.

While astilbe does like moist soil conditions, it does not like wet feet, so be sure not to let the water puddle at the crown and root areas.

Astilbe leaf shape

Astilbe leaves are very smooth and glossy and they contrast nicely with the feathery flower plumes. The edges of the leaves have serrated margins.

Some astilbe varieties are evergreen but many die back in the fall and go dormant until spring time.

Fertilizing and Soil requirements for Astilbe

Organic matter in the soil is beneficial.  You can also use a slow release fertilizer twice a year.

Astilbe is not not too particular about the type of soil. Astilbe will grow in soils that are loamy, soils with heavy clay content or even moist and slightly wet soil. An acid soil is desirable but astilbe will grow in soil with a pH of 6.0 – 8.0. Be sure the soil drains well.

How cold Hardy is Astilbe?

Astilbe overwinters in zones 3-9.  They don’t do as well in either extreme cold or heat zones. Be sure to check out other cold hardy perennial plants here.

To prepare your astilee for the winter months, remove stems and foliage down to the soil level in late autumn.  Cover the plant with a blanket of mulch.

Uses for astilbe

Because of its mounding habit, astilbe looks great when planted in groups. The flowers are good for a cutting garden and the plant is deer resistant and they attract butterflies.

Astilbe make great choices for garden beds under a canopy of trees.

Can astilbe be grown in containers?

It is easy to grow astilbe in pots and plants grown in containers may be the perfect choice for you is you have a semi shady patio or deck that needs a splash of bright color.

Astilbe can be planted alone in a container or mixed with other shade tolerant annuals and perennials.  Be sure the container is in a shady spot and water it regularly to make sure the soil does not dry out.

Astilbe is a great plant grown directly in soil, but also don’t mind being planted in pots.  (This makes it easy to find just the right sunlight spot.)

This unusually colored astilbe is called Straussenfeder Astilbe. It’s sold by American Meadows and is great for mass plantings.

    Love these plants…have been growing for years. I have divided them but they seem to have lost their bright colors. Any ideas of what I can do? thanks

    • admin
      08/01/2014 at 12:18 pm

      Hi Paula. Some astible varieties start out as one color and fade to white as the plant gets older. They also sometimes fade after they have been pollinated or if they are under stress, such as too much heat. But if yours are older, it may be that it is just their time to fade, since that is a natural part of the plant’s life cycle. Carol

    Hi! I found your site through pinterest looking for shade plants! These are lovely, but now that I live in New Orleans, I think they’re out. *Sad* I just wanted to comment because of two things. 1) I love the Gaia avi. Hehe. 2) I grew up in Raleigh so I thought that was neat too!

      01/16/2015 at 12:10 pm

      Hi Zel, Yes it is harder to grow astilbe in the hotter regions. I have to very shady areas here so they work pretty well….they don’t get much direct sun at all.

    Hi, the Astilbe drew my attention. It is so pretty, but I’m gathering it is not an annual. I moved into an apt. with a patio and a small space for growing flowers. I’m trying to think of what to plant. I want something bright, annuals of course. I get part shade, part sun. Last year I put in Impatiens, petunias and mums. Do you have any ideas? Thank you.

    • admin
      05/05/2015 at 10:32 pm

      HI Marilyn. I do actually grow perennials in tubs as well. But when I choose annuals, I normally pick something tall like a dracena to give height to the planter and then fill in with things like begonias, petunias, vinca, ivy, etc. A lot depends on how much shade you get. If it is too much, many of the annuals won’t do very well, but if you have grown pentunias you should be okay with pretty much any annual from the garden centers. Another favorite of mine is caladiums!

      This year, I am going to try and do more perennials in my tubs. I’m kind of tired of having to do them over each year, and my perennials will come back for me in tubs in zone 7b.

    The astilbe are gorgeous. Sadly, the astilbe I’ve planted have failed to thrive. Every year, they come back, but look scraggier and scraggier. I live in zone 4, so I’m wondering if I should move them to a sunnier spot to see how they do. Thanks for a helpful post on what seems like a little appreciated plant in the Midwest!

      05/11/2015 at 11:00 pm

      Hi Rikke. You could try. Last year, I planted a slightly shady part of what used to be my vegetable garden. It gets afternoon sun but shade in the morning. It is HUGE this year and so healthy, so they can take some sun as long as it is not all day long. Let me know how you go!

    These are beautiful! I am getting married on August 29th this year and was thinking about planting this so I can cut some for the wedding (just in little vases here and there… nothing major in case it doesn’t work). When would you suggest planting them? And any idea how long they survive once cut? Thank you so much.

    • admin
      05/20/2015 at 10:43 am

      Hi Claire. I plant Astilbe in the spring, but it takes several years for plants to get the size of these. I’ve never cut the flowers so I am not sure how long they would last in vases. I do put butterfly bush flowers (similar texture and size) in water and they last for several days.

          03/24/2017 at 10:27 pm

          Hi Trish, yes you can divide the plant in the spring or fall. This makes for a healthy plant and encourages good growth. However it is not a good idea to divide before you have grown them for three years. In my experience, they need a few years to flesh out the original plant. If you divide them when they are too young, it will weaken them.

      06/20/2015 at 7:41 pm

      Hi JD,

      I have had mixed luck with them. Most of mine are in the shade but my best one is in full sun in a south facing garden. It’s a mystery, since they are supposed to love shade. It could be lack of water. They don’t like to be wet but they definitely like more water than some shade plants. Astilbe is prone to a couple of fungal diseases which if left untreated can kill the plant. Powdery mildew one and leaf spot is another fungal disease that affects astilbe. Are you giving it plenty of water? If it is not in full shade, the sun can really amp up the moisture needs for it.

      Hi Darcy. I live in NC and it gets pretty hot here and I don’t have to water them all the time. In fact, my established ones rarely get additional water. I’m not sure if SC would require extra watering. It depends on whether you get much rain. Here in NC, we get showers later in the afternoon quite often.

    I have had Astilbes growing in a shaded garden for many years and have pretty much, unfortunately, ignored them. I just happened on to your How to Grow Perfect Astilbes on Pinterest and it has inspired me to give them some TLC this fall! I think I will dig and divide them and give some or all of them new spaces in which to grow! Thanks for providing incentive that I needed.

      03/10/2016 at 10:28 am

      HI Cheryl. I live in NC and have mine planted in garden beds that face north east and they do just fine. The beds get sun in the morning and shade in the afternoon. Astilbe does better in cooler climates but I still have good success with it here in the summer. Carol

    Great timing for running across this post! I bought some Astilbe but haven’t got them planted yet, and didn’t know anything about them. I been wanting some for a while. The package says to plant in full sun, but I have found out that lots of plants that says full sun doesn’t like the Texas sun. I wanted to plant some in the shade up along the fence, but wasn’t sure if they would do very good. Thanks for the tips!

    • Carol
      03/23/2016 at 7:39 pm

    05/07/2016 at 6:06 am

    I live in zone 4 in Kansas. I had three astilbes and one made it after three years and I realized the difference was the water and the partial shade. I have the white astilbe with my hostas and coral bells and it is beautiful every year but it does require extra water or it starts to look dead. The other two plants were in more direct sunlight and did not receive enough water and they completely died. So my advise is extra water and shade!

    • Carol
      05/07/2016 at 9:47 am

      Thanks for adding your experience Michelle. I have had similar results. My astilbe that was growing in full sun tends to suffer as the summer progresses, so I moved it to a shadier spot and it is much happier. Carol

    I love these flowers. Mine bloom but not all summer. Have them in the shade with bleeding hearts. They seem to be crowded could this be the reason they didn’t continue to bloom? When do I want to thin both plants out?

    • Carol
      07/01/2016 at 9:51 pm

      Hi Linda. Yes, if perennials are crowded, they will not flower as well. Thinning the plants is typically done in the spring, but early fall also works. It is best to not divide them until they are about 3 years old or so. Once they have been divided, this encourages more growth. Carol

    • Carol
      07/13/2016 at 10:57 am

      Hi Sharon. It’s hard to say what it is without seeing the plants but it sounds like it would be powdery mildew. If that is the case, they won’t flower and could die, so cutting them back is in order. When they start growing, trim some of the shoots so there is good air circulation around the plants. Generally this condition is caused by high humidity. Carol

      08/04/2016 at 12:09 pm

      Hi Marilyn. Is it just the flowers or the plants that are turning brown? Astilbe need plenty of moisture or they will suffer. Too much sunlight can also be a big problem for them. My astilbe start out pink but turn brown as the flowers fade. Could it just be that which is happening?

I’m not a great gardener as I tend to over water my plants, I just think that is the cure for all dying plants 😂 I’m learning that’s not true at all. I’d love to get some astilbe plants. What do you suggest? Am I thinking wrong or could they survive? Thanks

    • Carol
      05/17/2018 at 10:21 am

      The shady area would probably be fine but very few plants do well in sandy soil and astilbe is quite susceptible to the high temperature extremes so it might not be a good choice for this spot. Carol

      Hi Mary. Sometimes when perennials get older they need dividing to continue to bloom well. (after about 3 years) Astilbe is a heavy feeder and might not flower unless you fertilize it if your soil is not nutrient rich. While Astilbe can take some sun, it does prefer a shady spot. Any of these could be the reason. Carol

    Hi – I’ve read several articles on these plants and can’t find the info I need. I just planted 4 plants in a fairly shady spot. They had beautiful flowers on them when I planted them. The flowers are now dead. Do I cut off the flowers now? Will new flowers come this summer? I’m in Michigan – we’ve had an extremely hot summer – been giving them lots of water which appears to have been a good idea! Thanks. Leslie

      Hi Leslie Deadheading astilbe won’t encourage new flowers, so you can remove them now or wait until the fall when the plant dies and goes dormant. The plant does not bloom all summer long. It depends on the variety. Some bloom early spring, some mid summer, some late summer, but when they bloom is when they bloom. Carol

    Hi I’m in UK and just had my garden made over and have 3 Astilbes. Can you tell me do they flower more than once, and should I cut them back when flowers die off to encourage new flowers? They are so pretty

      Hi Jean. They won’t flower a second time. The best way to get all season bloom is to plant cultivars that bloom late spring, mid summer and late summer, then you will have all season bloom. The bloom time is quite long but they don’t repeat. Carol

      Hi Petro. Astilbe is hardy in zone 3-8. In very hot and dry climates, they need to be planted in the shade and/or given plenty of water. Carol

    I bought an Astilbe root (in a bag) from HD. Planted it in a shady part of my front yard Houston, Tx. Kept it watered. Never saw anything shoot up. We don’t have deer or rabbit problems here, so don’t have a clue what happened. My azeleas and coleus are doing great in same area.

      Hi Peachy. It could have been the rabbits and deer, but if nothing actually grew, it could also have been root rot, or a plant that just wasn’t viable. Most do grow but occasionally some don’t. Carol

    Can they grow in north Louisiana? I live in West Monroe and I adore this plant, although I wish it liked full sun.

      Astilbe will grow in zones 3-9. It does not like extreme hot and cold and definitely does not like full sun.

    Astilbe is a perennial shrub. The first ones hatched in June / July. Others are only in August and September. So if you buy astilbe, always watch the flowers. Because if you choose the same skillfully, you can enjoy the whole summer on the sea of ​​flowers. Astilbes is best used in small groups. They personally follow larger neighbors visually.

    I have had the same astilbe plant for many years. Each year it grows taller. It is on the corner of the house so in the morning it gets full sun and the afternoon, shade. This year it reached 7 feet high. It’s a freak of nature!

    Over several years, I have planted astilbes in my shady yard which is used as a salad bar by deer. The next spring, the astilbe that I planted the previous year does not appear. I don’t think that insufficient water is the problem; the ferns in the same area are flourishing. Coral bells also do well there. Maybe the astilbes needed fertilizer; I hadn’t known that this was a requirment. Any other ideas.

    • Carol
      07/25/2019 at 9:45 pm

      Hi Hildagarde. I’m not really sure what the problem could be. It’s possible that the deer ate so much of the plant that it weakened it so that it wouldn’t grow back. Astilbes also like to be divided every four or five years, as well, but this is just to keep them flowering.

    My astilbe bloom every year, but only the bottom half of the flower is fuzzy and colorful. The top half remains brownish and closed. Any idea what I could do to get them to fully bloom?

      The main reason for poor blooms on astilbe is too much sun. Do you have it in a shady spot?

    The article I am looking for. Your article gives me another approach on this topic. I hope to read more articles from you.

    For many years, I have tried to develop phlox and astilbe when participating. I bought many varieties, I wore a lot of money, but they didn’t live with me. Tell me what my fault is I put it on the ground in mid-May, I brought with humus. Accepted and even grown, but in the heat, the leaves begin to dry. I have a panic: I started spraying twice as much for everyone in turn – from diseases and pests. But saving the tree failed

      Astilbe doesn’t like high heat and if it gets too much sunlight it will suffer in the summer months. Move it to a shadier spot to see if this helps.

    I just bought some false spirea (astible falso) as I am looking for low care perennials and am starting with three plants. The tag says 6 -12 inches tall and 15-18 inches wide. Can you tell me the difference between this plant regular astilbe? I have read that is sends stringers and can be invasive. Can you tell me more about this? Also, my neighbor has a black walnut tree in their yard and it is toxic to many plants. Are astilbe affected by juglone?

    • Carol Speake
      04/25/2020 at 1:15 pm

      I have not found astilee to be invasive. I haven’t grown it near Black walmuts, but this page will give more information about juglone.

    The deer in my neighborhood love to eat the astilbe flowers. I have to spray with deer repellent to keep the flowers from being eaten.

    I planted an astilbe in a north facing garden with little morning and more afternoon sun–mostly filtered by a large pine tree. We have had a lot of rain this summer. It turned brown and dried out and died. I was told it was either entirely too wet from all the rain or too much sun. I live in Colo. zone 5. I would like to try again—what do you think?

    • Carol Speake

      I can’t diagnose individual plant problems without seeing the plant, but it seems more likely excess rain than too much sun in the location you mentioned.
