Hypericum perforatum
Perforate St John's wort is a herbaceous perennial plant with extensive, creeping rhizomes. The leaves are yellow-green, with scattered translucent dots. The dots give the leaves the 'perforated' appearance. The flowers are coloured bright yellow with conspicuous black dots and appear in broad cymes at the ends of the upper branches, between late spring and early to mid summer.
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.
