Make the most of it: Growing 20-30cm high and spreading about 1m, it’s perfect for hanging baskets, window boxes and containers where it can hang over the edge. It’s also spectacular as a border or massed in a bed.
Propagate: Take soft wood cuttings or sections of rooted stems in spring.
Good companions: Blue fescue grass (Festuca glauca), snow-in-summer (Cerastium tomentosum), white agastache and achillea, Salvia â˜Snow Nymph’, campanula, heliotrope, Lobelia siphilitica â˜Fan Blue’, catmint, rosemary and lavender.
Also known as Clerodendrum ugandense, this evergreen shrub gets its name from the butterfly-like, two-tone blue flowers and long, curved wispy stamens.
Growing tips: Full sun is best. In a frost-free area, plant it in a warm position. Water during summer. Cut it back in spring; it flowers on new wood.
Make the most of it: It’s a good addition to a mixed border as it grows 1â”2m high.
Good companions: Dark-foliaged, white-flowered Murraya exotica, salvias like S. â˜Mystic Spires’ and white and blue hebes like â˜Midsummer Beauty’ and â˜The Orb’.
It’s the depth and intensity of the blue flowers that catch your eye. Plus this neat shrub flowers from midsummer to the first frosts. You’ll also love the way the leaves turn a vivid red in autumn before dropping.
