Boswellia NEGLECTA

Boswellia NEGLECTA - Black Frankincense, Dakkara, Mogolo, Boswellia neglecta.

Can be grown in bonsai style!

Boswellia is a genus of trees and shrubs in the family Burseraceae, comprising about 24 species distributed across tropical Africa, Madagascar, the Arabian Peninsula, and India. Members of the genus are confined to dry rocky landscapes and open woodlands, where they form distinctive low-growing woody forms with fragrant, resinous bark.

Socotra frankincense is an endemic woody plant of Socotra Island (Yemen). It develops as a squat tree with a sculptural silhouette: the trunk branches early, with dense, sometimes slightly twisted branches. Leaves are odd-pinnate with a winged rachis, compact, lending the canopy an airy texture. The bark is dark gray and may peel in plates in mature specimens.

Flowers are small, gathered in inflorescences, and appear during the warm season. Fruits are dry, opening upon maturity. Seeds are equipped with thin wing-like appendages, which facilitates wind dispersal into crevices between stones where moisture is more easily retained.

Black frankincense is a drought-tolerant tree or large shrub with a thickened base and an irregular, picturesque crown. The trunk is often gnarled, with smooth or slightly flaking grayish-beige bark. Shoots are short, brittle, and branch well. Leaves are compound, pinnate, consisting of small oval leaflets that emerge during the growing season and may drop during the dry period, leaving an expressive skeletal network of branches.

Flowering occurs during the warm season. Flowers are small, white or cream, clustered in loose inflorescences at the shoot tips. After flowering, dry fruits form, dehiscing upon maturity, containing several small seeds inside that are often adapted for wind dispersal.

Seeds are small, dry, often equipped with thin wing-like structures. Before sowing, soaking for 8-12 hours in a weak solution of potassium permanganate with the addition of stimulants (SUPERthrive, HB-101, Aminosol, Epin, or Zircon) is permissible.

Sowing is carried out on the surface or with minimal covering in a sterile light mineral substrate based on sand with the addition of perlite or pumice. The sowing is moistened with a spray bottle, placed in a propagator or covered with plastic wrap, and germinated in light, but not in full sun, at a temperature of 28-30 °C (82-86 °F), preferably with gentle bottom heat. Seedlings require ventilation. Avoid overheating, waterlogging, and desiccation of the sowings.

Seedlings appear in 1-7 days; the minimum period is about 24 hours, and the maximum possible can exceed 21 days. After forming a pair of true leaves, careful prick-potting is performed, as the root system is sensitive to damage. After transplanting, humidity is gradually reduced and bright lighting is maintained to develop a compact crown.

Boswellia is cultivated under maximum bright light with mandatory access to direct sun. Indoors, it is placed by south-facing windows or in a dry greenhouse with good ventilation. Under insufficient light, shoots stretch and the crown loses compactness. During the warm season, maintain a temperature of 22-30 °C (72-86 °F). In winter, provide cooler and drier maintenance at 10-15 °C (50-59 °F). Watering is infrequent, allowing the substrate to dry almost completely between moisture applications. Stagnant water is not permitted.

Use a very loose mineral substrate based on pumice, coarse sand, and perlite with minimal organic matter. Strong drainage is mandatory. Repotting is carried out in spring as roots fill the container. Fertilizers are applied during the active growth period in low doses using succulent fertilizers with moderate nitrogen content. During dormancy, fertilizers are not applied.
