I have an Osteopermum Tresco Purple. By all accounts it should grow to a height of 30cm/12". Mine, that I planted in spring, has grown to about 60cm/24", about 100cm in with and still flowering at the end of November and has been a marvellous plant. I have the label that came with the plant and it is definitely the plant in question. Is it normal for this plant to grow into such a large bush? I have attached a photo of it when it was smaller in early summer.
