Butterfly bush (mix).
Physical Characteristics: A decidious shrub growing to 3m by 3m at a fast rate. It is hardy to zone 5. It is in flower from July to October, and the seeds ripen from September to October. The scented flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Bees and Lepidoptera (Moths & Butterflies). It is noted for attracting wildlife. We rate it 1 out of 5 for usefulness.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in nutritionally poor soil. The plant prefers acid, neutral and basic (alkaline) soils and can grow in very alkaline soil. It cannot grow in the shade. It requires dry or moist soil and can tolerate drought. The plant can tolerate maritime exposure. It can tolerate atmospheric pollution.
Habitats and Possible Locations: Woodland, Sunny Edge, Dappled Shade, In Walls, In South Wall, In East Wall, In West Wall.
Cultivation details: Requires a sunny position. Prefers a rich loamy well-drained soil. Very tolerant of alkaline soils, atmospheric pollution and maritime exposure. Grows best on dry soils of low fertility, where it can seed itself freely. Plants are hardy to about -15°c, they resprout from the base if cut back by cold weather.
A very ornamental plant, it hybridizes freely with other members of this genus. Polymorphic, there are many named varieties, developed for their ornamental value. The flowers emit a musk-like fragrance like heather honey. Plants flower mainly on the current years growth so a hard pruning in spring will encourage better flowering. An excellent plant for bees and butterflies.
Propagation Seed - cold stratify for 4 weeks at 4°c and surface sow the seed in February/March in a greenhouse. Germination usually takes place within 3-4 weeks at 21°c. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter, planting them out into their permanent positions in late spring or early summer, after the last expected frosts.
Seedlings are inclined to damp off and so should be watered with care and kept well-ventilated. Cuttings of half-ripe wood, July/August in a frame. Use short side-shoots. Very high percentage.
Cuttings of mature wood of the current season s growth, 15-20 cm long, October/November in a frame.
