Add bright summer color with Hemerocallis 'Rainbow Rhythm® Going Bananas' (Daylily 'Rainbow Rhythm® Going Bananas'), a compact daylily chosen for reliable performance and abundant bloom. You will get a tidy clump of straplike green foliage topped by scapes of lemon yellow flowers in summer, with repeat bloom often extending the display into later season. Each individual flower is short-lived, but the plant produces many buds for an ongoing show.
At maturity, this daylily typically reaches about 19-22 inches tall and spreads roughly 18-24 inches, making it easy to tuck into mixed borders, foundation beds, and sunny perennial gardens. Plant in full sun for the best flowering, but it also performs well in part sun where summers are hot. It is hardy in USDA Zones 3-9, and once established it is adaptable to a wide range of garden conditions.
For best results, grow in average, well-drained soil and water regularly during the first season to help roots settle in. After that, water during prolonged dry spells, especially while buds are forming. Remove spent flower stalks when bloom slows, and cut back foliage after frost if you prefer a cleaner look. Divide crowded clumps every few years to refresh vigor and keep flowering strong.
