The common name of this fascinating deciduous shrub conjures strange images–and it delivers. Attaining a length of 2 to 3 ft., bold pinnate leaves cloak an airy structure of stout, upright stems in tropical luxuriance. Amid young blue-tinged leaflets, which mature to dark green above and glaucus blue-green below, pendulous yellow-green panicles of dainty star-like blooms set the stage for extraordinary droves of beefy broad, 3 to 4 in. long, slate blue beans. Large decorative buds provide winter allure.
Blue Bean hails from the highlands of western China but is easy to grow anywhere, when planted in a moist well-drained location, it soars.
Size: 10' 0"–18' 0" high x 10' 0"–18' 0" wide; hardy to zone 6.
Decaisnea fargesii (S-0588)
