Lewisia cotyledon 'Sunset Strain' (Bitterroot) is a perennial coveted by in-the-know gardeners. Spectacular in flower, long-lived, and unique, this resilient native cultivar thrives in fast-draining gravelly sites and low fertility soil. With its compact form, it is a good fit for rock gardens, xeriscapes, sidewalk gardens, and containers. Flowering with the full colour spectrum of a summer sunset from apricot and tangerine to pinks and yellows and pure-white, the colourful flowers attract butterflies and bees from spring to fall.
