Other info. - "speciosa" means "showy" and the trees certainly are when in bloom. The panicles of this species are fewer flowered and shorter than the closely related C. bignonioides, but the flowers are larger and appear more dense in bloom. The two can be difficult to distinguish. The common term "cigar tree" derives from the appearance of the fruits.
