Named after the 'rainbow', this neat little perennial shows off its vibrant, tropical-coloured flowers, some single, some double, blooming all the way from May to September. Lewisia cotyledon 'Regenbogen' is known to be one of the most colourful mixes of Lewisia available. The blooms grow on short stems above neat rosettes of evergreen foliage. Lewisia likes hot, dry conditions and is drought tolerant once established. It will cope with cooler summers and can be overwintered outdoors if protected from wet weather. Height: 25cm (10).
