2006 I collected some seed from a very large rocky mountain penstemon and scattered them about. None seemed to germinate.
No experience.
2008 This image is a small rocky mountain penstremon in late spring. The plants seem to be perennial as I've noticed the plants often come up in the same place from year to year. I would like to try to transplant a small plant like this and to also collect seed and try to germinate the seed both indoor and outdoors.
