Penstemons love full sun and do better in the ground than in pots
Astillbes love moist soil so being in a pot is not the best idea

I've bought a Penstemon (apologies if spelling is wrong, my books are
downstairs) and four Astilbes today. Can I plant these in pots, or won't
they be happy. Grateful for any opinions please.
