Penstemon hallii

Common name Hall's penstemon
Family plantaginaceae
Life cycle perennial (Z4-8)
Flowers blue-purple
Size 6-8"
Light sun
Cultural notes well-drained soil

Penstemon native to high altitudes in the Colorado Rocky Mountains. Forms mats of dark-green grassy leaves, with purple flowers in summer. Sounds like a species that will be difficult to keep alive in our Pennsylvania climate - but I'll be trying.

This plant used to grow in our garden, but it slipped away...
