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.
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.
Tip for Growing 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.”
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.
Sunlight: 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.
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.
Size: 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.
Bloom time: The leafy green party of the plant grows steadily all spring and then about mid to late summer the long flower plumes will open up above the plant.
What to grow with Astilbe. Companion plants are those 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. See my list of good companion plants for Astilbe.
Propagation: 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 some of the smaller babies to get more plants for free.
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 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.
Watering: 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.
Leaf shape. The perennial astilbe has very smooth and glossy leaves which contrast nicely with the feathery flower plumes. The edges of the leaves have serrated margins.
Fertilizer requirements: Best to use slow release fertilizer twice a year.
Soil requirements: They are not too particular. Astilbe will grow in soils that are loamy, soils with heavy clay content or even moist and wet soil. An acid soil is desirable. Be sure it drains well.
Hardiness: Zones 3-9. They don’t do as well in extreme cold or heat zones.
Other facts: Great for cut flowers and deer resistant.
Uses: Astilbe make great choices for garden beds under a canopy of trees. It also is great when grown as a patio plant in a container on a shady deck or patio.
Border Plants Be sure to try growing Astilbe if you want a spectacular looking along a border edge as long as the bed that gets plenty of shade during the day.
Astilbes are great plants 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 unsually colored astilbe is called Straussenfeder Astilbe. It’s sold by American Meadows and is great for mass plantings.

Astilbe will flower best if it gets at least some sunlight. However, I have plants in a north facing border that gets very little sun and it will still give flowers.
