The corylopsis is covered with clusters of fragrant flowers and a very pale yellow, in the violet season.
The genus includes about thirty species of shrubs and small deciduous trees, all native to China or Japan.
In February and March, the corylopsis is a gardener's consolation when winter lingers! The pretty flower clusters appear before the leaves, and swing gracefully along the branches. After flowering, the leaves open, beautifully outlined and resembling the leaves of hazel. In the fall, the foliage will take on a pretty golden hue.
The corylopsis is not a demanding shrub if, from the start, you give it the right conditions for its development. It likes well-drained, rather acidic but rich soils (such ashydrangea where the camellia) and slightly shady situations and sheltered from strong winds. Good potting soil forestry suits it well, as does clay-siliceous soil generously amended in organic matter. Heather earth will only be added to correct the pH.
Install it against a wall, south-east orientation, and it will be perfect. You can even train it. It appreciates small temperature variations and the promiscuity shared with other shrubs. Late frosts can cause flower buds to abort and destroy the tips of young twigs. And, with repeated exposure to spring frosts, the plant can perish.
Corylopsis, late winter decor
Plant it near a passageway to take advantage of its remarkable scent, and preferably place it on a persistent background, to bring out its winter flowering more effectively. Any type of evergreen with dark green foliage will do. You can also plant in groups of 3 to 5 subjects in an undergrowth or in an open hedge. In small gardens, an isolated subject is always remarkable. A carpet of winter heather or early flowering bulbs like crocus, the scilles, the daffodils botanicals will create a charming ensemble.
The size is not necessary and will only serve to harmonize the silhouette just after flowering. Optionally, add a fertilizer for heather earth plants at the start of the vegetation and, towards the end of winter, a little "special rhododendron" fertilizer.
To maintain a certain freshness in the roots throughout the summer and to maintain acidity, mulch the soil with compost or pine bark during the spring. If the leaves turn yellow, water the soil with an anti-chlorosis product.
