The traditional rhododendrons and azaleas grown in our gardens are mostly native to China and Japan.
More and more, nurseries supply roses in containers. Bare root roses are convenient to plant, but don't leave it too late in the season when buds are swelling and roots may dry out.
Select your rose either by looking through catalogues or rose books or from notes made at earlier visits to rose gardens. Ask your nursery about new cultivars available each season.
Floribunda roses bowl me over. They may not quite have the romance of the old fashioned roses, but for floral impact, quality of display and ease of growth they are real winners. Many of them are the most popular roses, for justifiable reasons - they flower profusely, again and again, with only minimal efforts from the gardener.
