A very robust, pale pink clone (these are vegetative divisions) originally selected from wild populations by Carl Purdy (1861-1945). It has large, strong flowers with noticeably broad petals, a trait inherited from the californicum parent. The petals are a good soft pink and the plant has a very attractive poise. The base of the petals is yellow with a small pale zone, faintly dotted with orange-caramel spots.
Purdy wrote in Flora & Sylva that Pink Beauty was either a localised form or natural hybrid population with californicum or oregonum. In horticulture it has been much confused in the past, mostly with revolutum, but the differences are now unravelled.
This is a very good form for the garden in half shade and a humus enriched soil, one of the best.
