Aaron's beard "Rose of Sharon"
Hypericum calycinum
Aaron's beard "Rose of Sharon" - Hypericum calycinum.
Perennial groundcover with stunning yellow flowers during Summer, contrasting against a lush green background of dense foliage. Full sun to full shade. Perfect for foundations, mass plantings and embankments. Mowing in late Winter or Early Spring will rejuvenate the foliage.
Physical Characteristics An evergreen shrub growing to 0.3m by 1m at a fast rate. It is hardy to zone 6. It is in leaf all year, in flower from June to September, and the seeds ripen from September to October. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects. The plant is self-fertile. 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 heavy clay and nutritionally poor soils. The plant prefers acid, neutral and basic (alkaline) soils and can grow in very alkaline soil. It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It requires dry or moist soil and can tolerate drought. Habitats and Possible Locations Woodland, Sunny Edge, Dappled Shade, Shady Edge, Deep Shade, Ground Cover. Cultivation details Easily grown in any reasonably good well-drained but moisture retentive soil. Succeeds in dry soils and in chalky soils. Grows well in heavy clay soils. Succeeds in sun or shade but flowers better in a sunny position. Grows well even in the shade of tall trees. Tolerates poor soils and also drought when it is established. A very cold-hardy plant, tolerating temperatures down to about -25°c. A very ornamental but very invasive plant, spreading by means of stolons. Seldom sets seed in Britain, probably due to our wet autumns. Plants are often afflicted with rust disease. Plants in this genus are notably resistant to honey fungus. Propagation Seed - sow spring in a greenhouse and only just cover the seed. Germination usually takes place within 1 - 3 months at 10°c. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood 10 - 12 cm with a heel, July/August in a frame. Plant out in the following spring. Cuttings of mature wood, 12 - 17cm with a heel, October/November in a sheltered position outdoors. Plants root by the spring. Good percentage. Division in spring as new growth commences. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
