We have for many years had a hard standing on our front garden, as we all had cars including the children. Now they have all left home, we have decided to kango up about 12ft x 3ft and put in plants. Has anybody got any ideas what to plant. We do not want hedging, but something that is colourful during the winter and summer. The sun is on the front from 11a.m and all afternoon. The garden is also next to the pavement. We would like plants no higher than 12-18 inches high. Any ideas?
