Sphaeralcea munroana- note this is not the true name but one that has been used in the nursery industry. It is a low growing and spreading mallow to 3′. When it gets a little “ratty” cut it back and it will regrow and flower again. These are a little frost sensitive so it may burn back a bit in a hard frost. Very long bloom period from early spring to early winter.
