Rhododendron arboreum arboreum
Tree Rhododendron
| One of the most popular types are Azaleas, but the species, varieties, and hybrids number in the thousands. Rhododendrons can be evergreen or deciduous, and they vary from under 2 feet up to 80 feet in height. Generally found in clustered bouquets, they come in a variety of shapes -- funnel to bell-shaped, small and large. They range from the whitest of whites to cream yellows and from flaming oranges to fiery reds and the deepest of purples. When you buy plants, you may see a 2- or 3-number American Rhododendron Society code on the sticker. The 2-number codes indicate flower quality, then shrub quality, with 5 as highest and 1 as poor. Plant in acid soils. Mulch to protect shallow roots, but never cultivate the soil there. Protect from wind, salt spray and afternoon sun in hot climates. Watch out for root weevils and wilt diseases. Proper location and care will help reduce problems. |
White stamens and dark red spots accent the scarlet flowers. Handsome leathery leaves show off silvery-white undersides.
