Hayloft Plants are well known for their comprehensive penstemon collections but the vast majority of them have been raised close to their Worcestershire nursery. Now, they’ve introduced a prolific, but more dwarf, and more spreading variety discovered in California.
Penstemon 'Margarita BOP' reaches 18-14in/45-60cm in height, with a similar spread, and from late spring into late autumn is covered with spikes of sky blue flowers which take on more purplish tones as they mature. It’s ideal in gravel, or tumbling down a low bank or over a low wall.
It was found in the early 1980s by Bert Wilson of California’s Las Pilitas Nursery, the name 'Margarita BOP' is a combination of "Margarita" in reference to Santa Margarita, California, where Las Pilitas Nursery is located, and the acronym BOP for "Bottom Of Porch", where the chance seedling was discovered.
On his nursery’s website Bert Wilson explains: “It is a hybrid between Penstemon heterophyllus and Penstemon laetus. Every year it would flower and be gorgeous, clear sky blue, fading to purple, at the bottom of our front porch. We've never watered it nor maintained it. Every year we talked about how beautiful, neat, clean it was. The bicycles, skateboards and dogs had run over it tens of times but it still looked good at the Bottom Of the Porch, it still looked young after 7-10 years.”
The original plant only died, after 14-18 years, when it was covered in 2in/5cm of cement during renovations!
Happy in any sunny and well-drained site, this is a remarkably tough plant. It’s drought and heat tolerant, but also hardy down to -12C/10F. If it can take these conditions at Las Pilitas Nursery, between San Francisco and Los Angeles, it will thrive in Britain as long as the soil is not too wet.
