Threadleaf Bluestar
Amsonia hubrichtii
Pickup currently unavailable at Aiken Nursery
Threadleaf bluestar is grown for two seasons at once: a haze of soft, powder-blue stars in late spring, and a billow of fine, needle-thin foliage that turns a blazing clear gold in fall. Native to the Ouachita Mountains of central Arkansas, Amsonia hubrichtii forms a large, dense, shrub-like clump of upright stems clothed in those threadlike leaves, and the autumn color alone earns a place in any sunny border.
We believe this now popular plant was first made available by Woodlanders, well before the Perennial Plant Association named the species Perennial Plant of the Year in 2011. The pale blue, half-inch flowers gather in terminal clusters atop three-foot stems, and the milky sap that runs in every Amsonia leaves the plant untouched by deer and rabbits. An easy, long-lived, almost trouble-free native for the sunny border with well-drained soil.
Give threadleaf bluestar room to swell into a soft, fine-textured mound, lovely massed, repeated down a border, or set where the gold fall color can catch low autumn light. Striking beside late asters and grasses, and a generous foil to bolder leaves through summer.

From rooting to shipping, our top priority is ensuring you receive healthy, thriving plants for your garden’s success.
Because most of our plants are grown from rooted cuttings — alongside seed, air layering, and grafting chosen for each variety — you receive a stronger, true-to-type plant that establishes quickly in your garden.
Raised on organic soil blends and eco-friendly pest management — never harsh chemicals — your plant arrives healthy for your garden, your family, and the pollinators they feed.
Every purchase gives back. We donate to the Aiken Arboretum and support local wildlife conservation, so growing your garden helps protect the wider ecosystem too.
All our plant material is carefully propagated, grown, and nurtured at our humble nursery in Aiken, South Carolina.
Your plant arrives carefully packed and ready to settle in. Unpack them promptly, give them a day or two to acclimate, then plant following the notes we include — that’s all it takes. Clear care guidance comes with every order, so success is the easy part.
What to expect upon delivery
All our plants are sold in 1-gallon sizes, though the height of each plant can vary depending on its growth rate and seasonality, typically ranging from 1/2 to 2.5 feet.
Each plant is carefully packaged with its roots enclosed in a secure plastic bag containing moist soil, forming a compact root ball. To ensure safe transport, the box is padded with recycled newspaper, providing both stability and eco-friendly protection from weather during shipping.
