'Mulberry Jam' is an interspecific hybrid between Salvia involucrata and an unknown species. The other parent is speculated to be Salvia chiapensis. It was found in the California garden of Betsy Clebsch. It is a gorgeous Salvia that grows to around four feet tall and starts blooming in midsummer, continuing until frost. Emergence after winter doesn't occur until late spring. Plants that are overwintered without freezing can start blooming even earlier. It is less brittle than its S. involucrata parent but can still benefit from protection from strong winds. It is very popular with hummingbirds and hummingbird gardeners.
