caused me to toss around some resources and recollections
most initial pertinent resources would be the the American Penstemom Society and a fairly decent technical seed catalog;Granite Seed.
not such a a fan of Penstemons save P.ambiguus
which finally placed within another plant family (Flora of North America).
i have harvested seed from 6 foot plants so the 3’x3’ mature plants is inaccurate.
used GA 3 at 200ppm 24 hr soak and followed with clear water rinse prior to planting for more uniform
germination.( i have consulted with Dr . John Harrington who has published works in Native Plants Journal ) an alternative is rhizomatous, clonal propagation.
the fibrous roots tent out from the crown.bumping to small pots doesn’t work.transplant 5 seedlings (centered) directly to a one gallon nursery container with a media consisting of a #8 silica builders sand and perlite.very finicky to ( periodic) synthetic fertilizers. grow on fairly dry. :)
Interesting! I haven’t tried Penstemon ambiguus at all. I tried P. strictus in seed trays with little luck, but they have spread readily in the beds where planted. So I chop and drop which seems to help them spread here! ❤️🌱
I love garden updates! Say, do you do anything about the rhubarb flowers? I remember reading somewhere that I should remove the flowers so the plant spend more energy elsewhere. Thoughts?

Yep! I cut them off. I want the plant to put more energy into roots and leaves and delicious stems!
