I have had this penstemon for 3 years. It has overwintered in the severe Minnesota winters, especially last winter. It does not bloom, I just realize that it is in part shade. Will move it to full sun in the spring.

I bought a few of these penstemons this spring. They are a yellow-flowering variety. Said to be more tolerant of regular watering than other penstemons common in my area. I cut them way back when planted, and they haven't quit blooming since, and I live in hot western arid CO. The big test will be the survival rate over the winter. I know it says they are evergreen, but I've never had an evergreen variety which didn't die down to the ground over the winter (or die outright). Absolutely requires well draining soil, but I may mulch this winter. We shall see.

Blooms last for a long, long time. Lower stems become a little woody. Easy care, drought-tolerant, heat and sun-loving.

Considering this penstemon is native to Northern Mexico, New Mexico and Arizona, it is surprisingly resilient species. It does surprisingly well in Newfoundland's wet winter climate growing in acidic soil, considering it prefers hotter, drier climates and alkaline soil. Flowers may be small, but the bright reddish-orange colour makes up for it. the plant is almost like a dwarf conifer when not in bloom.
