One of the smaller Penstemon....but a beauty! The flowers have a bit of an opalescent sheen to them, and are just so pretty, the plants stay nice and compact, they bloom forever(!!!), and are reliably perennial if given great drainage, and a collar of gravel to prevent water staying there - but otherwise....GREAT!!

Margarita BOP [Bottom of the Porch] has beautiful flowers and is loved by hummingbirds as all penstemons are.
Curious about the name? The plant comes from Las Pilitas Nursery, where they say, "Penstemon 'Margarita BOP' was a seedling that came up sometime in the early 1980's. 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."
Soil, sunlight, and watering can all change the flower color.
