I grow several osteospermums .....they usually survive winter down here (west cornwall)
no, they dont seed but cuttings are very easy. Depending on variety some will layer themselves...e,g, cannington roy and tresco purple....or you can assist this process by pegging a stem or two down into the soil.
Cuttings can be taken from early spring through to autumn and root quickly. Cuttings will make flowering plants for the following year.
