Azalea × 'Gibraltar' (also sold as Rhododendron 'Gibraltar') is a deciduous Exbury azalea grown for a show-stopping spring display of bright orange, lightly fragrant flower trusses. You can use it as a specimen shrub, in a mixed shrub border, or along a woodland edge where its color can shine while the plant keeps a natural, open, upright form.
Give your azalea acidic, humus-rich soil that drains well but does not dry out completely. A consistent mulch layer helps protect shallow roots and supports even moisture. Water deeply during dry spells, especially from bud set through bloom and again during summer heat. Avoid sites that stay soggy, and avoid alkaline soils that can lead to poor vigor and chlorosis.
Site the plant in full sun to part shade. More sun generally improves flowering, while some afternoon shade can help in hot or exposed locations. Mature size is typically in the 48-72 inch height range with a broad, rounded spread, so leave room for air flow and for the plant to fill in naturally over time.
Prune only as needed, and do it right after flowering so you do not remove next year's buds. Deadhead spent trusses if you want a tidier look, and keep mulch pulled back from direct contact with the stems. With the right soil acidity and steady moisture, this cultivar becomes an easy-care spring highlight that returns year after year.
