Considered a native of the West, but this is a cultivar of unknown origin (to me). Most online sources avoid using the species epithet, munroana, which supports a non-commitment to place. There are some references to finding one in bloom in a U.K. garden with this unusual color, but S. munroana is described in the Sunset Western Garden Book as reddish orange. My eyes cannot tell the difference between coral-red and reddish orange. I will need convincing that this is actually a new cultivar worthy of a modified name.
We planted this in the garden two years ago, and it has slowly but successfully adapted to our dry garden, being native to a similar hydrozone. Annie's Annuals recommend cutting back each year to 12" - 18", and it has indeed bushed out more densely. Sunset recommends removing old wood, but we haven't had that opportunity just yet.
