Hypericum hirsutum
Hypericum are fast growing evergreen, semi-evergreen or deciduous shrubs. The low growing forms are suitable as ground cover. This species has hairy leaves and hairy stems. It is a medium to tall erect plant. Flowers are pale yellow and sometimes red-veined borne in a lax many flowered panicle. The sepals are covered in tiny black spots.
Flowering Season
From Early Summer TO Early Autumn
The 3 inch flowers are borne singly and are produced in succession from early summer through to early autumn.
Planting
From Late Autumn TO Late Winter
Plant out in any well drained, fertile soil from autumn to late winter in a sheltered border in full sun. As these shrubs are late-flowering, it is advisable to give them wall protection in northern gardens.
Propagation by cuttings
From Early Spring TO Late Summer
Take heel cuttings, 3-4 inches long from half-ripe lateral shoots preferably with a heel at any time between spring and late summer. Insert into equal parts of sand and peat in a propagating case at a temperature of 16C. When rooted, pot the cuttings singly in 3 inch pots of John Innes No 1 and overwinter in a cold frame. The following spring, pot on into 4 inch pots and plunge outdoors until planting out in autumn.
