Check out the botanical name on this one because there are several plants that go by the name rose mallow. This plant is a large, bushy annual with the flowers that resemble hibiscus, a relative and member of the Malvaceae family. The flowers are not only large but they are also produced in abundance to make a very grand show all summer if they like the climate. Of course, this can be a problem. They are native to the Mediterranean region and so like cool evenings, warm days, and dry climates, not common to most of the U.S. This is a plant I don’t even bother with in my North Carolina garden but enjoy and cherish in southern California. If I really wanted to grow it in the South I could do so early in the season and just accept the fact that it is a short lived annual there. Since it is best started from seed, the outlay of money for the plant is not great; it does not like to be transplanted so is best planted directly into the garden. Known since at least 1833 it is an heirloom plant that would bring a nice touch of nostalgia to any garden. If you like to bring flowers in for the vase, this is a good one for flower arranging.
