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 grower and heavy budder, it is unusually hardy, richly fragrant, and easy to grow.
'King George' is a tall hybrid rhododendron that blooms in mid-spring, producing huge pale pink flower clusters that turn white as they mature. It generally grows 6 feet tall but may reach a height of 12 feet. With rhododendrons, the rule of thumb is that the larger the leaf, the less sun they can handle gracefully. 'King George' and other Loderi rhododendrons are large leaf plants that follow this rule. However, if given enough shade they are also drought tolerant. [
