I divide mine in the spring. My 'Husker's Red' seeds itself, so I assume
that they would be easy to grow from seed. You should research to see if
the seeds need a cold period before they geminate.

Penstemons often resent being dug up & might take over a year to recover,
or not recover at all; but if never ever divided, huge old clumps will
become less & less flowery.

Some grow true from seeds, most do not.

The ideal & swiftest method is to just plant new ones to replace the old.
New plants are easily restarted from cuttings in a coldframe which is the
main method of propogation of plants that are true to the parent cultivar.
When the cuttings are well enough long to put into their permanent
locations, the worn out clumps go to the compost & replaced by the
youngsters.

I think this depends on the variety - my Husker's Reds have been moved
several times. Don't seem to mind at all.

I cut back the flowering stems and cut them up so I have a still piece
of stem about 3-4" long with a pair of leaves at the top. Stick it in
the dirt in a shady spot and keep watered. Move to sun in the fall. Last
year I did about 20 of them and had plants this year that bloomed. Maybe
50%, but I didn't baby them enough to get more.

This also works well on Sour Grapes Penstemon and a lot of other plants,
too.

I didn't do well with the seeds.

I also have 'Husker's Red' which doesn't reseed, but it does produce
off shoots. Gulf Coast penstemon comes true from seed, and doesn't
mind being moved at all.

many thanks to all who replied....you have been most helpful and informative
many thanks again
