14 Best Hardy Perennials

Budget conscious gardeners have a very good friend when they turn to growing perennials. What is not to like about a plant that comes back year after year and needs very little care and watering after the first year?  There are many types of perennials, from tender types, which need to be grown in the southern part of the USA, to very hardy perennials that keep coming back after a freezing winter outside.

Hardy perennials are those that will take a freeze and come back for at least three seaons. These are my top 14 picks that will almost all grow from Maine into the deep South. thegardeningcook.com

For color all summer long, try growing these hardy perennials.

Generally speaking a hardy perennial will last three or more seasons even with a freeze over the winter. Depending on the zone you live in, hardy perennials will take varying degrees of sun.

I live in zone 7b (North Carolina) and my mother, who was also an avid gardener, lived in Northern Maine, in zone 4a.  Many of these plants are those that both of us have grown successfully in our gardens.  

Astilbe

At the top of my list of my favorite hardy perennials is Astilbe, This is a wonderful perennial for shady garden spots

Astilbe is at the top of my list for one special reason.  I dug up many of my astilbe plants from my mother’s garden bed one year when I was visiting her in Maine. Her plants could take more sun than mine can.  I have to have mine in my shadiest borders. There is nothing quite like a shade garden plant that will still flower! Most are hardy in zones 4-9 and can take more sunlight the further north you live. For a look at all the colors of that this lovely plant comes in, see my Astilbe Photo Gallery here.

Shasta Daisy

Shasta daisies will form into large mounds quickly

Since my birth flower is a daisy, it is no surprise that I have Shasta daisies in my garden.  I’ve tried them in various garden beds. These perennials are hardy in zones 3-8,.and this is another plant that takes more sunlight the further north you live.  I was not able to grow them in my most sunny garden beds.  

Gaillardia

Gaillardia is also known as blanket flower.

Gaillardia, or blanket flower, is a daisy like perennial that will take more sunlight for me. This perennial is extremely resilient.  I changed the size of a garden bed last year and did not realize that I had some gaillardias growing outside of the new edge. They have been mowed over with a lawnmower and trampled on, but I still I discovered them growing this year!  Very hardy in zones 3-9.

DayliliesDaylilies are perennial plants that give a magnificent show of color in the garden

Daylilies are one of my favorite hardy perennials.  I have several varieties and colors in my garden beds, as well as Oriental and Asiatic lilies.  Having all three types, and some re-blooming varieties give me color all spring and summer.  Most varieties are cold hardy in zones 3-9.

Coneflowers

Echinachea, or coneflowers, are very popular with the bees and birds.

Echinachea, also known as coneflowers, are very hardy and drought resistant.  They are easy to grow and attract butterflies and bees to any garden.  I also leave the dried seed heads on the plant in the fall for the birds.  They are hardy in zones 3-9 and come in several colors.

Salvia

Blue Salvia flowers all summer long

Blue salvia flowers for me all summer long. The bees and hummingbirds both adore it.  Every time I admire the plant, there are always a lot of bees around it. the plant is super drought resistant and very easy to grow. It matures quickly and will be a very large plant in no time at all. This bush is about 4 feet tall.

Helleborus – Lenten Rose

Helleborus Cinnamon snow

There is nothing quite like walking around my garden in winter, with snow on the ground and seeing my Hellebores in full flower!  These cold hardy perennials will take the cold in zones 4-9, and the Christmas Lenten rose will go as cold as zone 3!

Hosta

Hostas are shade loving perennials

I have dozens of varieties of Hosta and so did my mother.  These shade loving perennials are hardy in zones 3-9 and get better and better each year.  They come in so many varieties and sizes.  I have them in all of my shady garden beds.  They flower, too, but the leaves are the reason that I grow them.

Rudbeckia – Black Eyed Susan

Rudbeckia - Black eyed Susan

I planted rudbeckia, also known as black eyed Susan, in my first garden beds when we first moved to North Carolina 23 years ago.  It spread like crazy and I took pieces of it and have it planted everywhere around my home. It flowers all summer long and into the fall.  It needs to be kept in check, or it will take over.  This variety is a dwarf rudbeckia that is easier to tame.  The perennial is hardy in zones 3-9.

Hydrangea

Hydrangea plants will give you an endless summer of flowers.

Hydrangea hardiness depends on the variety.  I grow the endless summer variety in my garden (zones 4-8) but the plant needs some protection in the coldest areas during the winter.  Mine started out as pinks and are all blue now. I have made a wreath with the flowers and they are very easy to water dry for indoor arrangements too.  They have very showy flowers and are one of my favorite plants. The farther north you live, the more sun they can take.  Mine need to be in semi sunny borders for best results.

Baptisia Australis

Baptista Australis - blue wild indigo

Baptisia Australis is a very hardy perennial.  It transplants well, although the roots can be quite deep and will grow in a HUGE plant in a short time.  My variety is Blue Wild indigo and has the prettiest flowers that the bees love. It is hardy in zones 3-9.

Red Hot Poker

Red hot pokers give a Southwest look to a garden bed.

Red hot pokers, or torch lilies, are not quite as hardy as the other perennials on my list.  It does best in zones 5-9, but is so easy to grow and quite different from my other hardy perennials that I wanted to include it.  I love the name and the flowers certainly do look like red not pokers, don’t they?  I have this perennial growing in my Southwest garden bed, with lots of cacti and succulents.

Dianthus

Dianthus is also known as Sweet William

Dianthus, also known as Sweet William is one of my favorite perennials.  There are two types – tender perennials, which are hardy in zones 8-10 and are treated as annuals in colder zones, and also hardy dianthus which can take the cold in zones 3-10.  Even though I am in zone 7b, my annual dianthus will still grow well for me after a cold winter, and is very pretty. It grows into a larger mound with each succeeding year.

Ajuga – Bugleweed 

Ajuga - also known as bugleweed, makes a great ground cover

Ajuga, also known as bugleweed, is one of the toughest plants that I have ever grown.  It started as a single plant in a small garden bed and quickly decided to take over. I dug it up and planted it under a large pine tree and it loved it there in the semi shade.  More of it went into a totally shady border and it took over that garden bed, too.  I dug it up from there and planted a foot of it in my Southwest border that didn’t have many plants in it and this year it is a patch that measures 8 feet wide and counting. Other plants will grow in the center of it (this hellebore is pervectly happy there) and it is cold resistant in zones 3-9.  If you are looking for a ground cover that keeps the weeds under control and has striking blue flowers throughout the summer, bugleweed is for you!  It spreads like a weed and keeps the weeds at bay!

    I love your list – I am a little bit colder than you, in zone 4b but all these are hardy for me too.

      Thanks Jacki. I am just on the edge of being able to grow tender perennials easily. We do get some bad freezes in the winter but not often.

    Thanks for the list! I have a lot of these in my yard and I just put rudbeckia in my yard this year. I’m excited to see what it does.

      Hi Kenda. Rudbeckia is very very lovely but be careful because it does take over. Carol

    I disagree with several of these. Deer love to eat hostas, for example. (Not truly hardy, therefore.)

    Try some rather low-maintenance plants that are deer resistant, ward off mosquitos, perennial and drought tolerant, too: pink sebum has lovely fall flowers, and simple le to propagate; lovage is of the celery family and can can be used in stews; sage is super easy to propagate; chives flower if you let them, so you should leave some sprigs alone to go to seed; and oregano is the most drought-resistant herb there is.

    These are some of my favorite things to grow, though. (I live in zone 4.)

      Hi Audrey. thanks for your suggestions. My comments about hardiness are pertaining to whether they are cold hardy. Deer eat many perennials, but that was not what I was intending to cover in my post. Carol
