White Kentucky Wisteria
Wisteria macrostachya 'Clara Mack'
Pickup currently unavailable at Aiken Nursery
The white form of the latest-blooming native. Wisteria macrostachya 'Clara Mack' is a twining, deciduous Kentucky wisteria with compound leaves and long, hanging clusters of pure white flowers, a splendid white version of a species normally blue. The racemes run longer and open later than those of the other native, Wisteria frutescens, extending the native wisteria season.
'Clara Mack' was found and shared by the late Clara Mack, a true country plant lady of Lexington County, South Carolina, and introduced by Woodlanders, where the selection has won praise at home and abroad. A gift from one gardener to the wider world.
Kentucky wisteria, once treated as a variety of the American wisteria and now considered a species apart, ranges through the south-central states and shares the family's best trait: restraint. The vine climbs a strong support without the decades-long land grab of the Chinese and Japanese wisterias, and blooms on new wood, so a hard prune never costs the coming flowers.
Give 'Clara Mack' a sturdy arbor, pergola, or post in full sun and well-drained soil, and prune after flowering and in late winter to shape. The long white racemes read beautifully against fresh green foliage and carry a sweet scent, a refined, non-invasive native for a structure that can hold a vigorous climber.

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.
