Smaller Penstemon with very large white or purple flowers. Interestingly, the central Oklahoma ecotype has white flowers, but as you head east the flowers are purple.
Height: 1-2 ft
Sun: full sun
Soil moisture: medium to dry, thrives in poor soils
Ecology: favorite of bumble bees
Other notes: typically plants that are well-adapted to poor soil conditions will be easily out competed in rich garden soils, so these may need special care and attention to ensure long-term presence in your garden.
