Rhododendron simsii 'HORT06' (HORTINNO CASCADULA) is a relatively good hardy garden azalea characterized by a cascade of drooping flowers. The flowers are fuchsia pink in colour and the small, elliptical leaves are dark green. This hangazalea is innovative in its kind and can be used in full soil, but also as a hanging plant in a pot on the terrace. The plant is protected by plant breeders' rights and is bred by Hortibreed NV from Lochristi (Belgium), which also submitted it for novelty testing.
