New and recent introductions make colourful cosmos as brilliant in the garden as it is in the vase. Annuals<\/a> are often looked down upon by some gardeners as not in the same league as perennials<\/a> but annual summer displays, like the one of almost 90 cosmos at RHS Garden Wisley<\/a>, makes it clear what valuable plants they are.<\/div>\n\n

As a mini-introduction, Cosmos bipinnatus<\/em> is a vigorous annual<\/a> reaching from 60cm to 3m or more, with stout upright stems carrying large, attractive, fresh-green foliage repeatedly divided into thread-like segments. From mid-summer into autumn, large golden-centred daisies open in a wide range of pink and red-rich shades with white.<\/div>\n\n
