I have bought various Penstemon seeds to plant this year....i would be very grateful for any info on the best method of sowing the seed....indoors, outdoors, in situ?...heat, no heat, cold frame?...Thanks in advance...:>)



I've never grown penstemmon from seeds but I'm interested to know the best way.

I've grown P. digitalis (Huskers Red) from seed - as I recall it was surface sown and covered with cling film before placing it on a windowsill in a warm room.
I used the same method for P. heterophylus (Electric Blue).
Both flowered in their first year.
