'Madam Galen' performs well in a hot, dry location. The complaint with this vine is that it grows too fast, mostly due to overwatering. It resembles a common relative, Campsis radicans, a moderate water plant. Orange Bells, moderate water relatives and hybrids of Yellow Bells, have similar flowers and the two are sometimes mistaken for one another.
