Amsonias

Highlights

Native amsonias put on a show 3x a year. In the spring, star-shaped blue flowers appear at the top of elegant stalks. (These plants can also go by the common name bluestar.) After the flowers fade, enjoy a wall of tightly packed leaves in the summer. In the fall, their leaves turn bright highlighter yellow. There are 10+ species of amsonia, most native to different parts of North America. Let’s make amsonias a new trend for North American gardens—they’re easy to grow and easy to love. Scroll on for planting tips and to meet some nursery-friendly species.

Amsonia looks amazing in groups—and up close.

Before dive right in, we just have to ask a question:

Why is amsonia a secret?

I’m being serious. Why do non-native tulips get the late-spring spotlight instead of native amsonias? Both bloom around the same time, but only one puts on a stunning display in the fall. (Tulips look amazing for two weeks, then drop their petals everywhere before withering up into stringy brown leaves, which remind me of hair caught in a shower drain.)

It is a mystery why these stunning native plants are not more widely known. It’s time for every American and Canadian in the eastern and southern regions to plant some and fix this in our lifetimes.

Is amsonia a good choice for my yard?

Yes, if…

• You want a low-maintenance perennial that requires minimal care once established.
• You have a spot with full sun to part sun and soil that drains reasonably well.
• You love three-season interest: spring flowers, summer greenery, and glowing fall color.
• You’re okay with a plant that grows 2–4 feet tall (or don’t mind cutting it back after blooming).
• You like planting in groups and want a big visual payoff from a few well-chosen plants.

Why amsonia matters

There are so many benefits to planting native amsonias. Some benefits include:

• Easy-care: once native amsonias are established (which usually takes the first year), they usually thrive on rainfall alone.
• They can be tall—unless you’d like them shorter: Most species get 3-4′ tall. If this is too tall for you, you can cut them to half their height after blooming.
• Lots of species for north-to-south options: Amsonia has multiple species that thrive throughout North America—scroll on to meet your favorites
• Flowers in the spring, foliage in the fall: As mentioned earlier, this plant offers multi-season interest and lots of visual drama

When we say multi-season drama, we mean it:

Spring

Enjoy their blue-tinted star flowers every spring. Amsonias bloom at the same time as peonies (which are non-native, but garden icons.)

Summer

After amsonias flowers fade, the leaves remain as a verdant wall. Thinner bladed amsonia leaves provide excellent textural contrast against summer blooming favorites like bee balm, coneflower, and mountain mint.

Fall

Amsonias turn shades of butterscotch in the fall. It’s like someone plugged your garden into a neon light socket. Pair with purple or blue native asters for a Monet-inspired fall.

Winter

Leave the stems up. They fade to the color of dry spaghetti and stand through most of the winter. When you cut them back in late winter or early spring, leave 12 to 18 inches of hollow stem, because small native bees nest inside. New shoots come up right through the stubble.

Types of native amsonia

There are 10+ species of native amsonia that offer resilient beauty for United States gardens. Here are some species you may encounter:

Eastern bluestar, or wideleaf bluestar

Amsonia tabernaemontana

(It has a few names—we’ll call it eastern bluestar here.) The range of eastern bluestar is huge: from Massachusetts to Texas! It thrives in full sun to part sun gardens and flowers in the spring. It gets a little tall—2-4′—if this bothers you, trim back the plant to half its height after it blooms. Thankfully, most local plant nurseries stock this plant.

Fringed bluestar, or Texas Amsonia

Amsonia ciliata

Native to the southern United States (from Florida to Texas), this amsonia offers more rounded blue star-flowers and needle-like leaves—a striking combo. It also comes with a bonus: the ability to thrive in hot southern summers. It’s a little shorter (18-24″) and needs well-drained soil to thrive.

Arkansas bluestar, or Hubricht’s bluestar

Amsonia hubrichtii

If one bluestar gets you hooked, it’s usually this one. Arkansas bluestar swaps the willow-shaped leaves for threads, so a mature clump looks like a soft green cloud that needs a comb. Powder-blue stars open in April and May. Then the cloud turns gold in fall, a color Mt. Cuba Center’s trial team called “exceptional,” especially in full sun. It was the 2011 Perennial Plant of the Year. In the wild it grows only in Arkansas and Oklahoma, but gardens from zone 5 to 8 suit it fine. Expect 2 to 3 feet tall and just as wide. Pick its spot with care: the deep roots make it hard to move later.

Shining bluestar, or Ozark bluestar

Amsonia illustris

Shining bluestar is the glossy one. Its leaves look freshly waxed, with wavy edges, and that shine is the quickest way to spot it at the nursery. It grows wild along streams and in wet prairies from Kentucky and Kansas down to Texas, which makes it a smart pick for heavy clay or the low corner that stays soggy every spring. Half a day of sun suits it best. Light blue stars open from March to May on plants up to 3 feet tall. In Mt. Cuba Center’s ten-year trial of 20 bluestars, a shining bluestar scored 4.8 out of 5. You may see it sold as Amsonia tabernaemontana var. illustris. Same plant.

Willowleaf bluestar

Amsonia tabernaemontana var. salicifolia

Willowleaf bluestar is eastern bluestar’s slimmer sibling. Botanists count it as a variety of the same species. Its leaves are long and narrow like a willow’s, so the clump looks lighter and airier than the wideleaf kind. Pale blue stars open in spring and can hang on into early summer, and the leaves go yellow-gold in fall. It grows wild across the South and north into Ohio, Indiana and Illinois. Plan on 2 to 3 feet tall in a loose vase shape (zones 3 to 9). Clay or sand is fine, even the edge of a rain garden. In shade it flops, so give it sun.

Woolly bluestar

Amsonia tomentosa

Woolly bluestar is the desert cousin. It grows in sandy washes and desert scrub from Southern California and Nevada east to Utah, Arizona, New Mexico and Texas, and it stays small, about 8 to 16 inches. Some plants wear gray, fuzzy leaves (the woolly part). Others are smooth and bright green. Pale gray-blue or white stars open from March into June. Nurseries rarely carry it, so ask your native plant society about seed swaps and plant sales. Give it full sun and soil that drains fast.

When do these amsonias bloom?

Looking for the other species?

Seven more bluestars round out the family. Most are rare in the wild and rarer at nurseries, so think of this as a field guide. Never dig one from the wild.

• Louisiana bluestar (Amsonia ludoviciana): Louisiana
• Rigid bluestar (Amsonia rigida): Georgia, Florida, Alabama and Mississippi
• Creeping bluestar (Amsonia repens): Texas and Louisiana
• Palmer’s bluestar (Amsonia palmeri): Arizona, New Mexico and Texas
• Jones’ bluestar (Amsonia jonesii): Utah, Colorado, Arizona and New Mexico
• Tharp’s bluestar (Amsonia tharpii): New Mexico and Texas, and critically imperiled in both
• Kearney’s bluestar (Amsonia kearneyana): Arizona only, and on the federal endangered species list

No matter which one you plant, there is one to avoid.

Let’s not plant European bluestar

Planting flowers, shrubs, and trees native to North America is what The Plant Native is all about. Which is why we should steer clear of one amsonia that’s native to Europe: European bluestar (Amsonia orientalis). Take a moment to check the nursery tag to make sure you’re not planting this bluestar species if you’re gardening in North America. You’ll miss out on all the benefits of planting native.

Where native amsonia shines in your yard

These plants can be a focal point in a foundation planting, alongside a driveway, or at the back of a pollinator garden.

Amsonias live for 10-20 years

Planting amsonia is one of the most beautiful and lazy types of gardening. (There is nothing wrong with wanting beauty for less work!) Plant these native beauties, and they can last for 10-20 years, slowly growing outwards from their starting clump.

Amsonia planting tips

As you add this native star to your yard, we have a few planting tips:

Plant 5+ native amsonias together for maximum impact

Amsonias look best when planted in groups. If you have the space, plant five or more near each other to help their spring flowers, summer greenery, and fall foliage shine. When you’re planting in groups, this next tip comes in handy.

Try to get all the bluestar you need at once

Perhaps you’re detail-oriented—like we are… no shame!—and you’ve noticed that some of the eastern bluestar pictures here and elsewhere online feature slightly different leaf shapes and flowers in varying shades of blue. We were skeptical too—is this the same plant?

Leaf shapes and flower colors for eastern bluestar can vary widely

Eastern bluestar (Amsonia tabernaemontana) has lots of different varieties that are rarely mentioned on plant nursery tags. Plants with needle-like leaves and others with fuller leaves may both be called eastern bluestar. Same for flowers that are a light blue or a bluer-blue; they might all go by the same name.

This variation is normal for amsonia. The Flora of North America database notes:

“[Eastern bluestar] Amsonia tabernaemontana encompasses a great deal of morphological diversity, particularly in leaf size and shape and sepal indument and length, which is to some extent geographically correlated; therefore, the recogni­tion of varieties seems desirable. However, the varieties are not well differentiated and tend to blend into one another, especially where their ranges overlap.”

If you want all your amsonia to “match,” buy all you need at once. You may find a different variety another season or at a different nursery. Or, embrace the varieties and collect all you can find, and enjoy spotting the tiny differences.

What are good pairings for amsonias?

A great rule of thumb when planting a garden is to pick native plants that bloom from spring to fall, so that pollinators always have a treat. Since amsonias are spring bloomers, pick some other great natives that bloom in the summer and fall to plant alongside. Some ideas include:

Where can I buy native amsonia?

Looking for places to buy amsonia? Here are four sourcing ideas:

If picking native plants feels overwhelming, try three-color landscaping. Pick three colors (one of which will be blue, since you’re planting amsonias) and stick to that palette. Here’s our guide to Three-Color Native Gardens to make it easy.

And that sums up our love letter to planting native amsonias. These beautiful and striking native flowers have been strangely overlooked in landscaping—let’s change that! Amsonias deliver star-filled flowers in the spring, greenery in the summer, and jaw-dropping foliage in the fall. Plant them in groups of 5+ for the most dramatic display. Since they are perennials, plant once and they will come back year-after-year. Don’t forget to pair with natives that bloom in the summer and fall, so your garden will always be filled with flowers and pollinators. Keep the pollinator party going and visit amsonia’s cousin, in our Beginner’s Guide to Native Milkweeds, or pair with a native tree from our Best Native Trees for Front Yards. Happy planting!
