Go green in winter:Not all perennials die down for winter; a few, helpfully for gardeners, hold on to their foliage, and can be relied on to provide valuable colour and form during the colder months

摘要

Not everything dies back in winter, thankfully. Certain plants keep a leafy presence, helping to dispel winter gloom and offering an important refuge for hibernating insects. In severe weather, such *wintergreen' foliage (see p40) can get frayed around the edges, but it recovers quickly once the weather improves. There are aromatic and fleshy-leaved silvers weathered by sun, or early-flowering woodlanders waiting for spring sunshine. Others form lush rosettes, and there are grass-like plants, too. Some have leathery leaves, others are ferny, but all add texture and form in the bleak midwinter.
