Calluna vulgaris, commonly called heather or ling, is a low, evergreen shrub prized for its fine texture, bee-friendly nectar, and carpets of late-summer to autumn color. Native to acidic heaths, moors, and bog margins across Europe and parts of Asia Minor, it forms dense mats of wiry stems with tiny scale-like leaves and abundant bell- to urn-shaped flowers in whites, pinks, and purples. Many cultivars offer varied bloom seasons and striking foliage that bronzes or reddens in winter. Calluna prefers poor, acidic soils and excels where drainage is sharp yet moisture is reliable. It’s an excellent choice for rock gardens, banks, coastal sites, and naturalistic plantings, and it combines beautifully with other ericaceous plants like dwarf conifers, blueberries, and rhododendrons. Though hardy to severe cold, it resents heat, humidity, lime, and waterlogged conditions. Regular light post-bloom pruning maintains a compact, floriferous mound. In containers, use an acidic, free-draining mix and protect from winter wet.

How to care for Common heather
Water
Keep the root zone consistently moist but never saturated. In active growth and bloom, water when the top 1–2 cm of soil feels barely dry, allowing excess to drain freely. Reduce frequency in winter, especially in cold, wet climates, to avoid root rot. Use rainwater if possible to maintain acidity and prevent lime deposits. In containers, check more often during hot, windy spells; water thoroughly, then let excess drain—never leave pots standing in saucers.
Light
Provide full sun (6+ hours daily) for best flowering, foliage color, and tight habit. In cool-summer climates, all-day sun is ideal. In hotter climates or at lower elevations, shift to morning sun with light afternoon shade to reduce stress and bleaching. Too much shade results in lank growth and sparse blooms. Indoors, light is generally insufficient; grow outdoors or in a cold frame/bright, unheated porch if containerized. Ensure free air movement to deter mildew in humid weather.
Nutrients
Heather evolved in nutrient-poor, acidic soils and needs minimal feeding. Use an ericaceous (acid-loving) fertilizer low in phosphorus and without lime, applied sparingly in early spring as new growth begins. One light application at half strength is usually sufficient; overfertilizing reduces bloom and encourages lank growth. Avoid manures, composts, or tap water that raise pH. Top-dress with acidic mulch (pine needles or fine bark) to supply trace nutrients and sustain soil acidity.
Temperature
Hardy outdoors in USDA Zones roughly 4–7 (cultivar dependent). It tolerates freezing winters, especially with snow cover, but dislikes prolonged heat above about 30°C/86°F. In hot-summer regions, provide afternoon shade and excellent drainage to mitigate heat stress. Container plants appreciate root protection from deep freezes and drying winter winds. Avoid warm, stagnant indoor conditions; cool nights and moderate daytime temperatures (10–21°C / 50–70°F) favor compact growth and sustained flowering.
