Heather Calluna vulgaris 'Radnor' (d)
ABOUT
Calluna vulgaris 'Radnor', commonly known as Heather, is a small, evergreen shrub that boasts a profusion of tiny, bell-shaped flowers that can range in color from white to various shades of pink or purple. These blossoms typically cluster along the plant's slender, upright stems, creating a delightful effect as if the branches are covered in a colorful mist of blooms. The leaves of Heather are small and scale-like, providing a fine, textured appearance. They are often a deep green color and may take on bronze or coppery tones during the colder months, adding to the plant's year-round interest. As Heather flowers from late summer into fall, it can become a highlight in the garden when many other plants are beginning to wind down for the season. Heather is known not only for its ornamental qualities but also for being a hardy plant that can adapt to a variety of conditions, though it prefers well-drained, acidic soils. With its dense, mat-forming growth habit, it can serve as an excellent groundcover or a complement to other plants in a mixed border or rock garden. Heather is beloved by gardeners for its ability to provide vibrant colors and textures throughout the year, as well as for its attractiveness to pollinators like bees and butterflies.

WaterFor Scotch heather, watering should be thorough but infrequent to encourage deep root growth. Allow the top inch of soil to dry out before watering again. Generally, this might mean watering once every week to every two weeks, depending on your climate conditions, with about 1-2 gallons per plant for each watering session. Overwatering or allowing the soil to remain soggy can lead to root rot, so ensure good drainage. Adjust the frequency during hotter, drier periods by watering more often, and reduce watering during the winter when the plant is dormant.
LightScotch heather thrives in a location where it can receive full sun to partial shade. It should get at least 4-6 hours of direct sunlight per day, but it can also tolerate some light afternoon shade, especially in hotter climates. The best spot would be an east or west-facing garden that gets morning or late afternoon sun, avoiding the intense midday heat which can sometimes be too harsh.
TemperatureScotch heather prefers cooler temperatures and grows well in environments where the temperature ranges from 40 to 70 degrees Fahrenheit. It can tolerate a minimum temperature down to 20 degrees Fahrenheit and a maximum temperature up to 80 degrees Fahrenheit. The ideal growing conditions would be an area with cool summers and mild winters, where temperatures stay within this range most of the year.
PruningPruning is essential for maintaining the shape and encouraging new growth in Scotch heather. The best time to prune is in spring, just after flowering finishes, to avoid cutting off the flower buds for the next season. Prune lightly, removing only the upper third of the plant's growth. It is recommended to do this annually to keep the plants from becoming woody and to promote compact, lush foliage.
CleaningAs needed
SoilHeather (Calluna vulgaris 'Radnor') thrives best in well-draining, peaty or sandy soil mixed with organic matter. Aim for a soil pH that is acidic, ideally between 4.5 and 5.5. A mixture of 50% peat, 30% perlite, and 20% organic compost can create an optimal growing medium for Heathers.
RepottingHeathers should be repotted every two to three years. It is best to repot Calluna vulgaris 'Radnor' in the spring before new growth begins to ensure minimal stress to the plant.
Humidity & MistingHeather prefers moderate humidity levels but can tolerate fluctuating conditions. Aim for relative humidity around 40-60% for optimal growth.
Suitable locationsIndoor
Place in bright, indirect light & water when topsoil feels dry.
Outdoor
Full sun; shelter from winds; well-drained, acidic soil.

Life cycleThe life cycle of Calluna vulgaris 'Radnor', commonly known as Heather, begins with seed germination, typically taking place in spring when the temperature and moisture levels are conducive to growth. Following germination, the seedling phase involves the development of root systems and the first shoots. As the plant enters the vegetative stage, it grows leaves and stems, gradually maturing over several years, and Heather is known for its hardiness and evergreen nature. The reproductive phase sees the plant producing characteristic purple flowers, usually from late summer to fall, which are pollinated by insects, leading to seed development. Once pollinated, the plant will produce seed capsules that release seeds when mature, completing the cycle. Throughout its life, which can span several decades in the right conditions, Heather will undergo periods of growth and dormancy, typically experiencing dormancy during the cold winter months.
PropogationPropogation time
Late summer to autumn
Propogation: Calluna vulgaris 'Radnor', commonly known as heather, is typically propagated by semi-ripe cuttings. The most popular time for taking these cuttings is during late summer or early fall, when new growth has started to mature but is not yet fully hardened. To propagate heather in this way, a gardener would select healthy, non-flowering shoots and cut a 2-4 inch (5-10 cm) length, just below a node. Leaves on the lower third of the cutting should be removed, and the base dipped in rooting hormone to encourage root development. The cuttings are then inserted into a mix of peat and perlite or sand, ensuring that the node where the leaves were removed is buried. The container is kept in a well-lit area, out of direct sunlight, and the medium is kept evenly moist until rooting occurs, usually within 4 to 8 weeks. After rooting, the new heather plants are potted individually and grown on until they are strong enough to plant out.
