Blue Moon Kentucky Wisteria
Wisteria macrostachya ‘Blue Moon’
Blue Moon is arguably the most versatile and gardener-friendly wisteria for many landscapes. As a Kentucky Wisteria (Wisteria macrostachya), it is native to the southeastern US, more cold-hardy, and most importantly, blooms reliably on new growth. This means it flowers at a younger age, reblooms readily, and can be pruned hard without sacrificing that year’s blooms.
-
Blooms reliably 1-2 years after planting and often produces multiple flushes of fragrant lavender flowers from late spring into summer.
-
Its greatest advantage: flowers on current season's wood. This allows for more flexible pruning and guarantees blooms even after a hard winter or severe pruning.
-
Slightly less vigorously vegetative than Asian species, making it more manageable for arbors, fences, and even large trellises where containment is desired.
-
An outstanding choice for Bay Area gardeners wanting spectacular blooms with less worry about pruning timing.
