Full sun; once established, needs only occasional watering. Fast grower to 25ft tall and wide. This gorgeous hybrid's upright growth habit and thorn less nature make this a fine shade tree. Large yellow blossoms create a dazzling display of color in the spring and last for a longer period than any other in the species. Tree may re-bloom in summer if given supplemental water. Even after the foliage falls, the stems and trunks remain green for color throughout the year. Produces very few seedpods. Prune for shape and structure after flowering.
