Rhododendron Bollywood®

Azaleas and Rhododendrons have been interbred since the first plants were scooped out of the dirt, and for a while these "crossbreeds" were even referred to by some ghastly name — Azaleodendrons or the like.

The old rule of thumb used to be that Azaleas are deciduous and Rhododendrons evergreen, but if that was ever true, it isn't anymore.

The differences between the two are slight, so slight in fact that botanists do not break them into the two groups that gardeners have come to know. Rhododendrons have 10 stamens per flower, while Azaleas have only five. While both can be deciduous, that trait is typically seen more in Azaleas than Rhododendrons. The shape of the leaves is often another indicator, with larger, paddle-shaped leaves typical of Rhododendrons, Azaleas often have smaller, elliptical leaves and trumpet, or tubular-shaped flowers at the ends of the shoots.

Planting:

Azaleas prefer a soil of high organic content, markedly on the acid side, ideally with a pH range of 4.5 to 6. If necessary, soil sulfur or aluminum sulfate should be added to acidify neutral or alkaline soils. Ample quantities of leaf mold, well-decomposed compost or peat moss, which will help make it acidic, should be incorporated into the soil prior to planting. Set plants out in a shaded or partially shaded location (the more shade the further south you are), in a location protected against drying winds. Soil should be moisture-retentive but well-drained.

Spacing is determined by the ultimate size of the plants chosen and by the rapidity with which you wish to achieve landscape effect – in general 3 to 5 feet apart is proper. Of paramount importance is the depth to which Azaleas should be planted – never set the plants with the top of the root ball any deeper than the surrounding soil level!

Maintenance:

Because they are shallow rooted, Azaleas should not be cultivated. Instead, use a mulch of for example pine needles or leaf mold. This will hold moisture and discourage weeds. In poor soils, or to enhance slow-decaying mulch, add a special azalea fertilizer in spring before new growth appears. Water deeply once a week when there is little or no rainfall. Prune after flowering only as necessary to remove dead or unwanted branches; pinching the tips of new shoots will encourage bushiness.

A Tradition of Distinction

Since its founding in 1920, Wayside Gardens has brought the rarest and highest-quality plants to the garden market. Wayside was founded in 1920 by two acclaimed growers who came together to pursue their shared vision of marketing all high-end plants for the serious garden enthusiast. Originally located in Mentor, Ohio, Wayside Gardens swiftly grew a reputation for the highest-quality plants and the most sophisticated clientele. In 1975, Wayside was purchased by the Park Seed Company, and moved to Hodges, SC.  The company has flourished since then, growing to become an undisputed leader in rare and unique plant growing.

Unparalleled Selection

Wayside's horticulturists travel the world in search of new and unusual plant cultivars and proudly offer the garden industry’s most sophisticated selection of high quality and rare perennial plants, bulbs, trees, shrubs, roses, vines, and indoor plants. Beginning with ties to the Dutch family bulb business in Holland, our horticulturists have developed close relationships with perennial and bulb growers throughout the United States and Europe, providing access to many rare and unique garden treasures. Throughout our history we have had the pleasure of introducing numerous exotic foreign and domestic plant cultivars to the American garden market. The Wayside collection of new and exclusive plant products is so preeminent that the catalog has long been lauded in the industry and is even used as a reference work in horticultural schools.

• Create a "puddling area" by digging a shallow hole filled with compost or manure where rainwater will collect and release essential salts and minerals.


• If you want butterflies to breed in your garden, put in some caterpillar food plants, such as parsley, milkweeds, asters, thistles, violets, clover, grasses, and Queen Anne’s Lace.


• Since butterflies need nectar throughout the entire adult phase of their lives, try to create a design that will allow for a continuous bloom – when one stops blooming, another starts.
