Rhododendrons comprise a large part of the total collection of plants grown at Branklyn. Many of the species were introduced by the great plant-collectors, Forrest, Ludlow and Sherriff together with Kingdon Ward. The garden is in close proximity to Glendoick Gardens owned by the famous Cox family who raised and supplied many of the Rhododendrons to the Rentons from the 1930s onward. The genus is represented by species and cultivars flowering from February right through to July, according to the season. Early-flowering species include RR. piercei and racemosum while a form of macabeanum will also produce an early flush of flowers. Highlights continue through the season with a large specimen of R. ‘Cynthia’, splendid foliage contrasting with flowers on R. bureavii. There are a number of sweetly-scented Azaleas, notably by the entrance to the garden, including R. ‘Branklyn’. Into the main body of the garden visitors will enjoy the vibrant orange flowers on R. coccinea var. speciosa. Branklyn holds a number of National Plant Collections (run by Plant Heritage) including the Rhododendron Taliense section.
