1 Salvia nemorosa 'Caradonna’ from the mildly aromatic silvery green leaves to the violet flower spikes with purple stems. Bees love the flowers that stay looking sharp long after the petals fall, thanks to papery bracts that hold their colour. Dead-heading – either little and often or in one go – encourages new flowering side-shoots till October. 'Caradonna’ loves sun; use it as a purple ribbon through late season grasses or, at 18in (45cm), it is the perfect centrepiece for a pot.
Rose campion is unforgettable in full bloom because of its abundant hot-pink flowers. But before it puts on its floral show -- and after the flowers fade -- its silvery-gray leaves are ornamental on their own. Note: Rose campion can self-seed abundantly; some gardeners find it a bit of a pest once it's established. Name: Lychnis coronaria Growing Conditions: Full sun and well-drained soil Plant Size: To 32 inches tall and 18 inches wide Zones: 4-8
