This plant has grown to about three feet in diameter. It's one of the first bloomers in my garden and keeps yielding huge day-glow yellow flowers until late fall. It doesn't require much in the way of water, and has started volunteering around my garden (Albuquerque, NM).

Looks great trailing over walls and as a companion to lavender and sage.
