Malva sylvestris var. mauritiana (mallow) £6.99
Position: full sun Soil: moderately fertile, moist but well-drained soil Rate of growth: average to fast growing Flowering period: June to September Hardiness: fully hardy If you want something that will quickly grow to a decent height and provide you will masses of flowers over several months from early summer, then look no further. It is relatively short-lived, but you should get a couple of years out of it and it does put on a really impressive show. It will also set seed if it is happy in its given spot, so you will have more plants that will happily take the place if the parent when the time comes. Garden care: Avoid excessive feeding as this will usually encourage leafier growth and fewer flowers. Provide support when grown in more exposed locations.
