Penstemon x gloxinioides
Hooray! A long-lived and massive blooming Penstemon for our mild climate where, sadly, most Penstemons sputter out after a year or two. To 3’ high and wide, the bloom spikes come Spring THROUGH Fall and I don’t mean a few spikes at a time. Lots – just like in these photos! Good-sized, white-blushed-pink trumpets and substantial foliage looks super in mixed perennial and shrub gardens, even dry gardens! Side-dress with a little compost in Spring and Summer and cut back spent spikes regularly. Don’t worry, it doesn’t actually have thorns.
