Description

Cultivated heathers are often hybrids of Erica carnea x Erica erigena. The botanical genus includes numerous species. The species carnea has flowers from autumn to early spring, needle-shaped leaves, pink flowers united in racemes distributed throughout the foliage to colour the small, compact bush diffusely.

Heather is an evergreen perennial shrub with a generally compact and very low habit. Most cultivated varieties reach a height of between 20 and 50 centimetres, although some species such asErica arborea can reach up to 5-7 metres in optimal conditions.
The leaves are the first distinguishing feature: small, needle-shaped, arranged along thin branches and deep green, which in some varieties fades to yellow, rust or orange shades during the cold season. The flowers, a true ornamental highlight, have a characteristic bell shape and are grouped in spikes or terminal racemes on the previous year's branches. The colour palette ranges from snow-white to delicate pink, including deep purple, red and purple.

Curiosities and special features

One aspect that makes heather particularly interesting is its nature as a melliferous plant: bees love it and the honey obtained from it, especially from Erica carnea, is considered particularly valuable. There is also a curiosity that few people know: in the roots of heather lives a symbiont fungus called Hymenoscyphus ericae, which enables the plant to absorb nitrogen and phosphorus even in very acidic soils where other species would struggle to survive.

Origin and distribution

Species native to central and eastern Europe, particularly the central and western parts of the Alps and the northern Apennines.

Leaf

The small, needle-shaped, evergreen leaves are the first distinguishing feature ofErica carnea.

Leaf colour

intense greensolid colour that, in some varieties, fades to yellow, rust or orange shades during the cold season.

Plant height

The height of the plant varies from 0.2 to 0.5 m, making it ideal for creating dense, low evergreen canopies dotted with numerous inflorescences from winter to spring.

Lifespan

Evergreen, polyennial Species.

Where to plant

Plant habit and compact Growth make it suitable as a small shrub for flowerbeds, island traffic flowerbeds, borders, gardens and parks, rock gardens, pots.

Stem

Semi-woody stem with cracked-looking bark.

Flower

The flower is simple in form, small in size, with a bell-shaped corolla and single-coloured petals. It is arranged in raceme-like inflorescences of medium size. It flowers from late autumn to late spring, with a flowering period of between 20 and 30 days. It is attractive to bees.

Growth

Compact and proportionate Growth shrub.

Plant habit

The developed vegetative habitus is bushy.

Branching

It is characterised byabundant branching and high foliage density.

PH

Acidophilic plant requiring a Soil/medium pH of between 5.0 and 6.5.

Soil preparation

Before transplanting in mid-autumn provide a suitable planting hole size, proportionate to the development of the roots. Remove weeds and bulky pebbles, also ensure that the pH of the soil is suitable for proper growth ofErica carnea as it is an acidophilic species.

Sun exposure

Prefers bright sun exposure.

Ideal climate and temperature

It is an ideal plant for beds with a cold winter climate, withstanding even frozen soil. The ideal temperature is between 0.0 and 30 °C.

Use

The low, compact habit as well as the flowering that occurs during the colder season, when other species are in dormant, give Erica a primary role as a shrub in:
Outdoor ornamental

Hardiness

It is of medium hardiness, withstands winter cold well but is sensitive to prolonged water stress.

Soil

Requires predominantly acidic, well-draining and light Soil/medium. For pot cultivation, use a new medium specifically for acidophilic plants.

Difficulty

Under the right environmental conditions, the cultivation ofErica carnea is easy with a low level of maintenance effort required, thus giving the plant additional value in use.

Growing tips

Some specific cultivation indications
Balanced fertilisation Avoid over-watering In hills above 300 m. Can also stay in the sun all day. Keep the substrate dry at low temperatures Exposure to direct light

Planting

An average planting density of 4 plants per square metre is recommended in view of the bearing and size achieved. Transplant by completely burying the root ball and compacting the soil well in order to prevent the formation of air pockets that can compromise rooting.

Propagation

Multiplication is by cutting.

Watering

Water regularly with non-calcareous water, preferably rainwater, but avoid water stagnation in the substrate or soil, keeping the latter slightly moist.

Water directly at the base of the plant with frequencies and doses also commensurate with the climate during the different seasons; during the winter period, if temperatures are very cold, reduce watering.

Fertilising

Apply a specific liquid or granular fertiliser for acidophilic plants to the medium or soil, without exceeding the dose and frequency.

Edibility for humans

Non-edible

Tip

Its resistance to winter temperatures makes heather the classic plant for this cold season. Only if the temperature drops below -10 degrees should you place the pot in a more protected place and, especially with small pots, you should also make sure that the roots do not dry out.
