PERENNIALS |
||
For the 2010 season over 200 varieties and types of perennials will be on sale. There is no "one" season with perennials, they are available throughout the spring, summer and autumn. Their habits all vary and we only bring them on sale when sufficient growth has appeared. In an effort to grow only the best we plant all new varieties in the Trials Garden for evaluation. After this winter we will be looking with interest at the hardiness of many varieties |
