Incarvillea Olgae

This rare plant is quite unlike most others, being a tall, woody perennial, much like a taller I. arguta, but with smaller,and more, flowers, with open branches bearing tubular flowers with flattened faces. It flowers from late spring until the end of summer, with a very long succession of flowers, growing well in dry, poor soils, and is very hardy and easy to grow, being probably the longest-lived and most reliably perennial of all of the Incarvilleas.
