- Hardy to USDA Zone 5 C. × erubescens (Hybrid Catalpa) is a hybrid of C. bignoniodes × C. ovata, apparently it first originated in France in 1866, but the hybrid has occurred at other places and times. C. × e. Purpurea is the most common hybrid cultivar, there is some controversy as to its origin, but it may have been introduced before 1886 by T. Meehan's nursery in Germantown, PA.
