I bought a batch of Rose of Sharon shrubs from a mail order house about ten years ago. When they arrived, they were little twigs with a few roots. I planted a few of them around the yard and gave some away, as well.
Rose of Sharon is one of those shrubs that definitely has a season. It isn’t an all-season plant. The leaves are depressingly bland. The shrub’s shape is nothing to brag about, either. But come August, that difficult, quiet month when almost nothing is blooming, the showy Althaea flowers jump up and turn the plain Jane shrub into a Jane Russell superstar.
My future plans for these plants are to be more generous with food and water to coax more blooms from them each year.
