'Gibraltar'

Gibraltar is hardier even than other deciduous Azaleas and very mildew-resistant.
'Gibraltar' is an exceptional Exbury hybrid boasting huge trusses of flat, 2 1/2-inch flowers with broad, charmingly fringed, coppery orange-red petals. A mid-season bloomer and very heavy budder, it is unusually hardy, richly fragrant, and easy to grow.

All of our outstanding deciduous Azaleas are large flowered, deliciously fragrant plants that add a new dimension to Azalea colors. Easily grown and quite rugged, these beauties are highly mildew-resistant. 'Gibraltar' is so exceptional that it was given Rhododendron of the Year honors in 2007 by the American Rhododendron Society (ARS). It reaches 6 feet high and 4 feet wide. Full sun only in zones 5 and 6. Part shade in zones 7 and 8. Zones 5-8.

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:

Spacing will depend upon ultimate height and spread of the variety or species you’ve chosen. A cool, moisture-retentive, acid soil (pH 4.5 to 6.5), particularly one that contains a high percentage of organic matter to hold moisture, is best.

The location should, in addition, be protected against drying winds and winter afternoon sun. Rhododendrons are shallow rooted and should not be planted too deep: the heavier the soil, the shallower the planting. Do not fertilize at planting time.


Maintenance:

Keep plants well-watered, even in dry periods in the fall – a coarse mulch, 2 to 3 inches deep, to retain moisture and keep the soil temperatures cool, is beneficial. This will also keep down weeds, eliminating the need to cultivate, which could pose a danger to shallow roots. Spent flowers should be removed.

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.
