This group of shrubs is also a member of the pea family, but less aggressive than their larger relatives (Cytisus). They perform best given full sun, gravelly dry soil and once-a-week watering. They do not transplant well so don’t attempt to move it once you have planted it in the garden. Not bothered by rabbits, squirrels nor deer.
