This is the robust, horticulturally distinct, variant which is found in a small area of Serpentine cliffs and screes around Pulga Bridge in the Feather River valley of California.
It makes silvery patterned leaves below a large, white flower with a yellow glow in the throat
This plant, perhaps remarkably, does well in the garden, if kept in a sunny spot, well-drained, fertile and drier in summer making a superb show in late March and early April with decorative foliage and several flowers to each pair of leaves. If potted or kept in a pan, with careful management in an alpine house, it can make a superb show.
