Blue Moon Kentucky Wisteria is prized for its exceptional cold hardiness, fragrant flowers, and repeat blooming habit, making it a great choice for gardeners in colder climates. It grows fragrant, pea-like, lavender-blue to lilac-blue blooms cascading racemes 6–12 inches long (sometimes longer). It typically blooms in late spring/early summer (around June) and often reblooms 1–2 more times through the summer for an extended display. Flowers open somewhat simultaneously on the racemes for a dramatic effect. Compound, deep green leaves with 7–9 (often 9) leaflets provide a lush backdrop.
