Wisteria macrostachys
Kentucky Wisteria
Sun, Partial Shade
Zones 5-9, Grows 15 to 20 feet.
The hardiest and most restrained of all Wisteria. The hanging clusters (officially called racemes) are longer than Wisteria frutescens at about 1 foot. This is a US native (we don't offer any of the Asian, invasive species). The best show can be achieved by trimming your vine to four buds from last year's new growth just before this year's growth begins.
