Care of the shrub Hypericum grandifolium or Large-leaved Hypericum |
|
The genus Hypericum, family Hypericaceae, comprises some 400 species of herbaceous plants, shrubs and trees with a cosmopolitan distribution. Some species of the genus are: Hypericum grandifolium, Hypericum revolutum, Hypericum canariense, Hypericum calycinum, Hypericum olympicum, Hypericum polyphyllum, Hypericum roeperianum, Hypericum elatum, Hypericum fragile, Hypericum balearicum, Hypericum x inodorum. Common name: Large-leaved Hypericum. This species is native to the Canary Islands and Madeira. They are evergreen shrubs that reach 2 meters (6.56 feet) in height. The broad, opposite, ovate leaves up to 9 cm (3.54") long are light green. The attractive yellow flowers measure up to 5 cm (1.96") in diameter. They can bloom from spring to mid-autumn. They are used in light undergrowth, to form bushy groups and as isolated specimens. The Hypericum grandifolium prefers semi-shade exposure, avoiding direct sun in the middle of the day. They do not resist frost. They grow in all soil types but prefer well-drained soil that contains some organic matter. Water regularly so that the substrate does not dry out completely but never flood; they resist a few days of drought when they are established. Fertilize with a little compost at the end of winter. Lightly prune the tips of the branches after flowering to maintain a compact size. They are quite resistant plants to the usual pests and diseases. They are propagated from seeds sown in spring or autumn in nurseries. |
