Rainbow Rhythm® 'Storm Shelter' Daylily

Rainbow Rhythm® 'Storm Shelter' is a reblooming hybrid daylily with 5-inch mauve-purple flowers, a deep eggplant-purple eye and matching petal edge. Its clumping foliage supports flower stalks around 24 inches tall, with a mature spread of 18–24 inches. ## Garden Placement Grow in full sun to part sun in a border or mass planting, leaving room for the mature clump. This cultivar is listed for USDA zones 3–9 and grows in a range of ordinary garden soils. Keep soil evenly moist while roots establish, then water during extended dry periods. Its foliage forms a grassy mound and the flower stalks rise above it. ## Seasonal Interest The purple blooms open in succession and bring color through summer; several cultivars may rebloom under favorable conditions.

Divide crowded clumps when flowering weakens. The [RHS daylily guide](https://www.rhs.org.uk/plants/hemerocallis/growing-guide) describes general seasonal care and division.
