About
Catalpa speciosa 'Pulverulenta' is a gradually expanding tree characterized by its broad, heart-shaped foliage, which is prominently marked with creamy-white spots. In mid-summer, established specimens produce upright clusters of white flowers adorned with purple and yellow spots. These blossoms are succeeded by elongated, bean-like seedpods.
