Let's Dance Rave Reblooming hydrangea

Let’s Dance® Rave® is a compact, mounded bigleaf hydrangea with summer mophead flowers that shift from violet-purple in acidic soil toward saturated pink in more alkaline conditions; blue tones can develop where aluminum is available. It grows about 2–3 feet tall and wide and blooms on old and new wood; Proven Winners identifies the cultivar as ‘SMNHMSIGMA’, with USPP 26,929 and Canadian PP 5,628 ([cultivar profile](https://c4.provenwinners.com/plants/hydrangea/lets-dance-rave-reblooming-hydrangea-hydrangea-macrophylla); [patent record](https://patents.google.com/patent/USPP26929P2/en)). ## Form and Flowers Rounded flower heads rise above green foliage. This rebloomer begins with flowers on old wood and continues forming buds on new growth through summer. ## Garden Use Use it in a shrub or perennial border, as a low hedge, in a foundation planting, or for cut flowers. Its small footprint can also suit a large container if the soil stays evenly moist. ## Growing Conditions Give it part sun or sun, leaning toward afternoon shade in hotter sites. Keep the soil moist but well drained; bigleaf hydrangeas tolerate clay or sandy textures when drainage is sound. Flower color responds to soil acidity and aluminum availability.

If shaping is necessary, prune before August 1 so next season’s old-wood buds remain. NC State advises leaving dead hollow stems cut at 12–24 inches standing until they break down, which provides nesting places for stem-nesting bees.
