Calluna vulgaris 'Carnival' (Scotch Heather 'Carnival') is a compact, evergreen heather that brings year-round texture and late-season color to rock gardens, borders, and foundation plantings. You will appreciate its fine, needle-like foliage and its pink to purplish flower spikes that show from summer into fall. At maturity it typically stays low and mounding, about 6-12 inches tall, making it easy to tuck into smaller beds or use as a low edging plant.
Give your heather full sun for best flowering, but it will also grow in partial shade. Plant it in consistently moist, well-drained, sandy or rocky soil and avoid sites where water sits. Heather prefers acidic conditions, and it performs best where the soil is not allowed to dry out completely. Light pruning in early spring helps keep the plant dense and prevents it from becoming leggy over time.
Because it dislikes heat and humidity, choose a cooler, airy spot and avoid hot, humid microclimates. Use it in masses for a soft, natural look, mix it with other acid-loving plants, or place it on a slope where its spreading habit can help cover the ground without overwhelming nearby plants.
