Like deciduous trees, deciduous shrubs lose their leaves in winter. Evergreen shrubs, such as holly and rhododendron, keep their leaves all year round. Clematis are climbing shrubs that have weak stems but stay up by wrapping their stems around a support. Rhododendrons are among the most success-ful of all shrubs. They originate from Asia.
Magnolias are among the most ancient of all shrubs.
Garden flowers People have cultivated garden flowers for their scent and colour for thousands of years, and there are now countless different varieties. While wild dog roses have tiny, delicate pink or white blooms with just a few petals, garden roses tend to have large, many-petalled blooms in bright colours ranging from deep reds to purples and even blues. Wild roses also tend to have far fewer flowers and many more leaves than garden roses. Clary is a biennial with scented leaves grown for use in perfumes and to brighten garden borders. The Canterbury bell is one of many bellflowers grown in gardens.
