Tree Heath Erica arborea var. alpina
ABOUT
The plant commonly known as Tree Heath is an evergreen shrub characterized by its dense foliage and woody stems. The small, needle-like leaves are arranged in whorls around the stems and exude an appealing dark green hue, providing a vibrant and lush appearance throughout the year. When it blossoms, it produces numerous small, bell-shaped flowers, which range in color from white to a delicate shade of pink. These flowers typically cluster near the ends of the branches, offering a visually striking contrast against the dark foliage. The overall shape of the Tree Heath is somewhat conical, contributing to its popularity as an ornamental plant in gardens. The bark is also notable for its rough texture, which can add an interesting tactile element to the plant's presentation.

ToxicityTo humans
The Erica arborea var. alpina, commonly known as tree heath, is not widely recognized as a toxic plant to humans. There is limited information about its toxicity, but it is generally not considered poisonous. Therefore, it is not commonly associated with symptoms of poisoning or adverse health effects upon ingestion. However, as with any plant, individual allergies or sensitivities could possibly occur, so it is advisable to handle plants with care and not consume parts of plants that are not known to be safe for consumption.
To pets
The tree heath is not commonly known to be toxic to pets. There is little to no evidence suggesting that the Erica arborea var. alpina presents a significant risk if ingested by pets. However, the general rule of thumb with non-edible plants is to prevent ingestion due to possible individual reactions or sensitivities. While no specific symptoms of poisoning are generally associated with this plant, pet owners should still exercise caution and discourage pets from chewing on or ingesting parts of it. If a pet does consume tree heath and exhibits unusual symptoms, it is advisable to consult a veterinarian.

WaterThe most common name for Erica arborea var. alpina is Tree Heath. For watering Tree Heath, it is important to keep the soil consistently moist without overwatering. A good method is to water deeply and then allow the top inch of soil to dry out before watering again. During the growing season, this might mean watering with approximately 1 gallon per plant every week, adjusting for rainfall and temperature, to ensure adequate hydration. In winter, reduce the frequency of watering to match the reduced growth and evaporation rates. Be cautious of waterlogging, as Tree Heath does not tolerate standing water well.
LightTree Heath thrives in conditions where it can receive full sun to partial shade. To ensure the best growth and flowering, place the plant in a spot where it receives at least six hours of direct sunlight daily. However, in hotter climates, provide some afternoon shade to protect it from intense, scorching sun rays that can stress the plant.
TemperatureTree Heath prefers a temperate climate and can survive in temperatures that range from around 20°F to 75°F. It is important, however, that it is not exposed to prolonged periods below freezing or to extreme heat. The ideal temperature range for Tree Heath is between 50°F and 70°F, where it can grow most vigorously without stress from the environment.
PruningPruning Tree Heath is mainly done to maintain its desirable shape and to encourage bushier growth. The best time for pruning is in the spring after the last frost but before the onset of new growth. Pruning can be carried out annually if desired, to remove any dead or diseased branches and to tidy up the plant's appearance.
CleaningAs needed
SoilTree Heath (Erica arborea var. alpina) thrives in acidic, well-draining soil with a pH between 4.5 and 6.0. A soil mix containing peat moss, sand, and pine bark is ideal. Ensuring good aeration and drainage while retaining moisture is key for healthy growth.
RepottingTree Heath should be repotted every 2 to 3 years to refresh the soil and accommodate root growth. Repotting in the spring is generally best to allow the plant to establish in its new container before the growing season.
Humidity & MistingTree Heath prefers moderate to high humidity levels. Aiming for a relative humidity of around 50-60% would be suitable for this plant. Avoid excessively dry conditions to ensure healthy foliage and growth.
Suitable locationsIndoor
Ensure bright light, cool temps, and acidic soil for indoor Tree Heath.
Outdoor
Plant in partial shade, acidic soil, and water regularly outdoors.

Life cycleErica arborea var. alpina, commonly known as tree heath, begins its life cycle as a seed that germinates in well-drained, acidic soil, often in spring or after a fire event that stimulates growth. The seedling stage follows, where the plant establishes its primary root system and begins to develop its needle-like leaves. In the vegetative stage, the tree heath grows rapidly, developing a woody stem and branching habit, forming a shrub-like appearance that can reach up to 2-6 metres tall. The reproductive stage sees the development of clusters of small, bell-shaped white flowers that are pollinated by insects, primarily bees. After successful pollination, the flowers develop into capsules containing numerous seeds that, once mature, are dispersed by wind or animals to start a new growth cycle. In the final stage of its life, the plant may experience senescence, where growth slows, and it may die back, especially if subjected to extreme conditions, disease, or old age.
PropogationPropogation time
Spring to early summer
The most popular method of propagation for Tree Heath, Erica arborea var. alpina, is by semi-hardwood cuttings. This technique is typically done in late summer. The process involves selecting healthy, non-flowering stems and cutting them into lengths of 4 to 6 inches (10 to 15 centimeters). Each cutting should have several sets of leaves. The bottom set of leaves is removed, and the cutting is dipped in rooting hormone before being placed in a well-draining soil mix. It's important to maintain high humidity around the cuttings, which can be achieved by covering them with a plastic bag or using a mist system. Roots usually develop within a few weeks, after which the new plants can be gradually acclimated to less humid conditions before being transplanted.
