It's curious to me why I don't see this stunning perennial in more gardens. Hardy gloxinia has masses of large, exotic, bright pink, trumpet-shaped flowers in late spring. The lush foliage looks somewhat like Acanthus (Bear's Breeches). It will rebloom if cut back after flowering. Photo courtesy of Walters Gardens.

Grassy places and scrub around 2000m. Pastures and open grassland, 2400-3500 m., but it is now uncommon in its native range.
