Nursery contributed plant descriptions

It’s curious to me why I don’t see this stunning hardy gloxinia in more gardens. Incarvillea ‘Snowtop’ has masses of large, exotic, pure white, trumpet-shaped flowers in late spring. The lush foliage looks somewhat like Acanthus (Bear’s Breeches). It will rebloom if cut back after flowering. Give this unique perennial a try.
