Winterhazels (Corylopsis spp.<\/em>), native to China and Japan, represent a\u00a0group of winter flowering shrubs of varying heights and widths (USDA hardiness zones 5 to 8). Few U.S. gardeners know them. Their bright yellow colored flowers are larger and showier than witchhazels (Hamamelis spp.<\/em>). Flowering begins\u00a0as the witchhazels (they\u2019re related) are finishing up in late February\u00a0and March,\u00a0many weeks before forsythias bloom.<\/p>\n

The winterhazels are\u00a0welcome additions to shrub borders or woodland spaces. There are eight or more species available from on-line nurseries. Spike winterhazel (C. spicata<\/em>) and buttercup winterhazel (C. pauciflora<\/em>) are low growing or\u00a0spreading forms that\u00a0fit well into urban and suburban gardens. The lemony yellow flowers\u00a0have red-purple anthers and are\u00a0slightly fragrant.<\/p>\n

Spike winterhazel grows to 4-8 feet tall and to 6-10 feet wide.\u00a0Individual flowers, only 3\/8 inches long, comprise small drooping clusters (racemes to 2 inches\u00a0long);\u00a0clusters contain 6-12 flowers. After bloom, 4-inch long ovate to obovate leaves\u00a0unfold colored\u00a0bronze-purple and, within weeks, change to blue-green color. Tiny hairs on the leaf surface tend to collect dust over the summer, resulting in\u00a0a blah\u00a0yellowish-green fall color. Fruits are two-beaked capsules,\u00a0each\u00a0containing two small seeds.<\/p>\n

Winterhazels\u00a0prefer a compost-rich, well-drained, acidic\u00a0soil in full sun to part shade.\u00a0Winterhazels tolerate\u00a0most garden soils except heavy clays. Plants favor\u00a0shading from direct afternoon sun in southerly climate zones as well as shelter\u00a0from high winds.\u00a0Flower buds\/flowers are susceptible to\u00a0cold injury\u00a0if winter temperatures are severe.<\/p>\n

After flowering or by late spring, prune winterhazels\u00a0as needed\u00a0to\u00a0hold them in check. At the same time feed with 10-10-10 or equivalent\u00a0granular fertilizer. There are\u00a0no serious insect or disease problems.<\/p>\n","protected":false},"excerpt":{"rendered":"
