View prices and availability
A cultivated crossing between C. bignonioides and C. ovata. Has heavy main branches and grows from shrub into an average-sized tree. The initial pyramidal, but later round crown, is half-open. The hard wood breaks easily. The acuminate and entire, heart-shaped to ovate leaf appears late in spring and it has a slightly purplish-brown colour, later turning dark green. Young plants have a larger leaf, to 30 cm. It is shed relatively early. The white, tubular flowers are slightly smaller than of C. bignonioides and appear in erect, long panicles of 20 to 30 cm. Inside the flowers are yellow and have small brown spots. They are followed by 25 to 35 cm long capsules that are 1 cm thick. These persist during winter.
