Calluna vulgaris 'Alba Rigida'
ABOUT
Calluna vulgaris 'Alba Rigida', commonly known as Scots heather or ling, is a small, evergreen shrub renowned for its distinctive foliage and flowers. The leaves are tiny, scale-like, and borne in opposite pairs, lending the shrub a fine-textured, almost feathery appearance. Its growth habit is dense and mounded, which contributes to its popularity in garden landscapes. The 'Alba Rigida' variety is particularly notable for its attractive, white flowers that appear in late summer to fall, forming conspicuous, spikelike racemes that stand out against the green foliage. These blooms are favored by bees and butterflies, making the plant a beneficial addition for supporting local pollinators. Throughout the year, the plant displays a mix of colors, with the foliage sometimes taking on a purple or bronze tint in the cooler months, adding seasonal interest. This hardiness and color variation, combined with the contrast of the white flowers, make Scots heather 'Alba Rigida' a visually appealing and versatile choice for gardens.

WaterHeather, specifically the Calluna vulgaris 'Alba Rigida', should be watered deeply but infrequently, maintaining a consistent moisture level without causing waterlogged soil. Typically, heather plants should be watered when the top inch of soil feels dry, which could be once or twice a week depending on weather conditions. During hot, dry periods, more frequent watering may be necessary. A general rule is to provide about 1 gallon per plant per watering session for established plants. Adjust the amount of water you provide seasonally, reducing the frequency during the colder months when the plants are not actively growing.
LightHeather thrives best in full sun to partial shade conditions, requiring at least 4 to 6 hours of direct sunlight daily. The ideal spot for Calluna vulgaris 'Alba Rigida' is in a location that gets morning sun and partial shade during the hottest part of the afternoon to avoid scorching the foliage. However, it can tolerate and adapt to varying light conditions, making it versatile for garden planting.
TemperatureThe ideal temperature range for Calluna vulgaris 'Alba Rigida', commonly known as Heather, is between 60°F to 70°F during the day and slightly cooler at night. However, it can withstand temperatures down to 20°F and is hardy up to 80°F. Heather plants are resilient to cold and can survive winter months in many climates without issue.
PruningPrune Heather to maintain its shape and encourage new growth, typically after it has flowered. For Calluna vulgaris 'Alba Rigida', the best time to prune is in late winter or early spring before new growth begins, removing only the top third of the plant. Pruning should be done annually to prevent the center of the plant from becoming woody and to promote lush, dense foliage.
CleaningAs needed
SoilHeather requires well-draining acidic soil with a pH between 4.5 and 5.5. The best soil mix is a blend of peat moss, sand, and pine bark, which ensures proper drainage and acidity.
RepottingHeather should generally be repotted every 2 to 3 years to refresh the soil and accommodate root growth.
Humidity & MistingHeather prefers moderate to high humidity levels but is adaptable to less humid conditions as long as the soil moisture is maintained.
Suitable locationsIndoor
Provide bright light and cool temperatures for heather indoors.
Outdoor
Plant in full sun to part shade in acidic soil.

Life cycleHeather 'Alba Rigida' starts its life as a seed, which upon germination, develops into a small seedling. This seedling then experiences a period of vegetative growth, where it develops a woody stem and small, needle-like leaves typical of the heather plant. The plant reaches maturity and begins its reproductive phase, producing white flowers usually in late summer to fall, which are pollinated by insects. After pollination, seeds form and are dispersed by wind or animals, which can lead to the establishment of new plants. During winter, Heather 'Alba Rigida' enters a period of dormancy, with reduced metabolic activity, allowing it to survive cold temperatures. It will continue this life cycle, living for many years as a perennial plant, growing slowly and expanding its coverage of the ground.
PropogationPropogation time
Late summer to early autumn
Calluna vulgaris 'Alba Rigida', commonly known as Scotch heather, is typically propagated through semi-hardwood cuttings. The ideal time for taking cuttings is during mid to late summer, which roughly corresponds to July through September. To propagate Scotch heather using this method, select a healthy, disease-free stem and cut a piece approximately 4 to 6 inches (10 to 15 centimeters) long. Strip the lower leaves, dip the cut end in rooting hormone to encourage root growth, and insert it into a pot filled with a well-draining potting mix. The cutting should then be placed in a humid, indirect light environment until roots have established, which can take several weeks. Once rooted, the cutting can be transplanted into the garden or into a larger pot to continue growing.
