Calluna (Calluna vulgaris), also known as heather or ling, is a small evergreen shrub prized for its late-summer and autumn flowering, when its stems are covered with small pink flowers arranged in spikes. This specimen, approximately 25 cm tall, brings color to balconies, terraces, and entrances during the season when many other plants are dormant.
Calluna Characteristics
- Calluna vulgaris: compact evergreen shrub with tiny leaves and dense spikes of small flowers.
- Deep pink flowers, with some lighter spikes, stand out against the green foliage.
- Overall height of approximately 25 cm, with a 12 cm diameter pot.
- Flowers from late summer through autumn, with color that remains on the plant for a long time.
- Hardy: tolerates winter cold well outdoors.
- Ideal on its own in a pot or in autumn arrangements with other balcony plants.
Calluna Care Tips
- Light: Full sun or bright partial shade; more light encourages more abundant flowering.
- Water: Keep the soil slightly moist at all times, without waterlogging. It does not like prolonged drought: check it often when grown in a pot, especially on windy days.
- Soil: Acidic. When repotting, use soil for acid-loving plants and, if possible, water with low-lime water.
- Temperature: Hardy plant that withstands frost; it is instead sensitive to dry summer heat.
- Fertilization: In spring, use fertilizer for acid-loving plants.
- Pruning: In late winter, lightly trim the faded stems to keep the shrub compact and encourage new flowering.
- Placement: Perfect for balconies, terraces, planters, and entrances. In autumn, it can also decorate interiors for short periods, in a bright, cool spot away from radiators.
