Nemesia is a small bedding plant with many uses in the garden. Use them as edging plants, ground covers, in mixed borders, woodland plantings and as container or hanging basket plants. At a distance, Nemesia looks a lot like edging lobelia, with flowers that cover low-growing mounds of foliage. Up close, Nemesia flowers might also remind you of orchids. The top four petals form a fan with one large, sometimes lobed petal below. When temperatures are mild, the plant produces so many flowers that they almost completely obscure the foliage.
