I've got penstemon eatonii in the garden. It's a wonderful plant that doesn't mind a bit (I wouldn't say "thrives") neglect. I've had it rebloom consistently if you cut off the spent stalk. Leave some stalk and it will spread from seed. It is NOT evergreen here in zone 5'ish of western CO. Always dies back to ground (just like penstemon pinifolius). The hummingbirds adore this. I've got many other penstemon cultivars, but this one is THE favorite. Do not overwater or you will have root rot and possibly winter kill. It likes it high and dry.

Grew this from seed in 2007, it is in bloom now for the first time. A hummingbird has been at them daily. I would like to get a lot of plants going because they are rather dainty and I think you need a lot for them to stand out in the garden.

A non-hybridized wildflower, you can find this penstemon growing wild in the mountains in the Rocky Mountain west.

It's happy in bad soil, hot sun, and little water. Blooms mid-spring.
