My mom grew this penstemon from seed for me five years ago. It started with a bang and has continued every year since with a bang! Next year I am going to have to downsize it as it has taken over quite a large area. I find the blooms have an almost iridescent quality. My only complaint about this flower is that it only blooms in spring. It is so pretty I wish it would go all summer long!

Long-lived, which is unusual for most penstemons I've tried here.

I dug this penstemon from my mom's property in the Southern NM mountains (Sacramento Mountains) and brought it home to Colorado in '10. I planted it, watered it, and it "died." The following year it sprouted, but it never bloomed. In 2012 it bloomed for the first time. This year (2013), it's been blooming almost constantly for over 2 months. It gets pretty tall, about 3.5 ft. Hummingbirds, however, don't seem to like it as much as the agastaches next to it. I've found that the stems get "topheavy" and will topple over from the blooms.
