信息匹配。请阅读下列应用文及相关信息，并按照要求匹配信息。首先请阅读以下植物的介绍：

of shade to grow healthily. Has attractive white to pink flowers throughout the year.
B. Lantana-A fast-growing plant that develops best in full sun with dry but rich
soil. Grows about 60-90cms tall. Bright, colourful globe-shaped flowers that appear
in winter.
C. Russian Sage-It has grey leaves and purple flowers which come out in mid-
summer. Grows 1-1.5 metres tall and prefers full sun and dry soil. Can cope well
in poor soil.
D. Soapwort-A plant that grows 10-25crns tall. Prefers a full sun site. It can handle poor
soil but wm not survive well when conditions are wet over the winter months. Flowers
in spring.
E. Wishbone Flower-Suitable for both indoors and outdoors. It grows up to 15cms tall and has flowers that range in colour from pink to purple. Prefers a dry, cool, shady site as summer heat will cause it to decline.
F. Japanese Painted Fern-Attractive non- flowering plant that grows well in either rich or
poor soil. Prefers shade and soil that will not dry out-as this will cause its leaves to die
quickly. Grows 2-4 metres tall so needs a large area to maintain its health.
