Erica carnea 'Snow Queen'

Erica carnea 'Snow Queen' is a variety of Alpine Heather that stands out for its long and intense winter and spring white flowering, as well as its ability to cover or garnish the ground. Standing about twenty centimetres tall, it spreads to form a dense cushion, with evergreen foliage all year round. From December to May, it is covered in a multitude of small white bells that bring colour to a period when the garden can sometimes be a bit dull. Cultivated in pots or planters, it enriches a balcony, terrace, or window ledge with its refined flowers, and can even be used as a centerpiece for festive tables. This alpine heather is very hardy and robust, capable of withstanding cold, pollution, and sea spray, on poor, rocky, and even slightly chalky soils. Easy to maintain and requiring little care, it is accessible to all gardening enthusiasts.

Erica carnea 'Snow Queen' belongs to the family of Ericaceae. This heather, with its winter and spring flowering, is also known as snow heather or Alpine heather, due to its mountainous origins in central Europe (France, Austria, Germany, Switzerland) and southern Europe (Slovenia, Albania, Croatia, Macedonia, and Serbia). With healthy and robust vegetation, it forms a small evergreen shrub with a spreading habit, reaching about 0.15m (0ft) to 0.25m (1ft) in height and 0.40m (1ft) to 0.50m (2ft) in spread at maturity. It grows slowly and has a lifespan of no more than 12 to 15 years. On thin and twisted branches, small needles grow, measuring 5 to 7mm (0in) in length, arranged in whorls of 4, with a furrow underneath. The young shoots are a lovely light green in spring, turning dark green in summer, and eventually taking on bronze hues in autumn. This cultivar usually blooms between November and April depending on the climate, for several weeks. Its small bell-shaped white flowers, measuring 5 to 6mm (0.25in) in length, are clustered in 3 to 10cm (1 to 4in) long spikes and are scattered along the branches. The flower consists of a corolla in the shape of an urn or bell with 4 small lobes and 8 free stamens. The purple anthers protrude, giving the flowers an elegant appearance. They are highly attractive to bees.

The 'Snow Queen' heather has all the features one would expect from a heather. Long and remarkable flowering combined with ever-evolving evergreen foliage throughout the seasons. Its low, dense, and compact growth allows it to be used in ground cover beds, as borders for shrub beds, on slopes or rockeries, to dress the base of trees and large shrubs. It thrives in full sun but also tolerates partial shade very well. It can easily be planted alongside other heathers whose flowering will take over, while having a similar growth habit, such as Erica x darleyensis or Erica vagans. Its long winter flowering brightens up a period when the sun is often lacking.

Hardy down to -25°C (-13°F),  the 'Snow Queen' heather is a small, sturdy, and robust shrub. Easy to grow, it adapts to all types of soil, including slightly chalky soil. In any case, well-drained soil without stagnant moisture is necessary. It does not tolerate long periods of drought well and appreciates moist soil. Mulching is a solution to maintain relative soil moisture. Almost maintenance-free, this heather only requires light pruning after flowering, in April. This will remove faded flowers and promote fresh foliage. It is ideal for winter heather beds, to enrich the colour palette, alongside other varieties, such as 'Jenny Porter', a bright pale pink, or 'Rosalie', a vibrant carmine pink. It also adds whimsy and cheerfulness to low-growing grass beds such as Carex, Ophiopogon, Molinia, Uncinia, Hakonechloa, Pennisetum... It can also be mixed in a bed with dwarf creeping conifers (Juniperus squamata 'Blue Star', Juniperus horizontalis 'Blue Chip', Juniperus communis ‘Repanda’...), or ground cover plants such as silver basket or wall bellflower (Campanula portenschlagiana for example). It also occupies the front of beds, animating them throughout the year, especially in winter. Cultivated in pots or planters, it enhances a balcony, terrace, or patio with its intense flowering. For even more effect, it can be accompanied by Skimmias or creeping wintergreen Gaultheria (Gaultheria procumbens).
