Crowberry Facts

Plant Description

Crowberry is a low-growing, trailing, mat-forming, evergreen dwarf shrub that normally grows about 0.3 m (1ft) tall and 0.5 m (1ft 8in) wide and often forms dense mats. The branches are up to 40 centimeters in length. The plant is found growing in hygrophilous moors, mountain tops, drier parts of blanket bogs, mollies, snowy scrub, muskegs, open tundra, rock fields, conifer forests, coastal bluffs, exposed sea cliffs, meadows, open forests, alpine fell fields, and cliffs, forest heaths, rocky outcrops, barren bogs, subalpine parkland, and alpine tundra. Black crowberry is a calcifuge plant; which means that it avoids alkaline soils. They are easily grown in lime-free sandy peats and rocky soils, alluvial deposits, and glacial till. They are most commonly found in stagnant surfaces and mineral soils which are rich in nutrients and poor in nitrogen content. The soil texture should be between medium to fine.

The plant has strong primary roots, but as the plant age, a shallow root system with many lateral roots develops. Stems are slender, creeping, and rooting and are green to reddish colored. The twigs and branchlets especially when young are minutely stipitate-glandular and are not densely white-tomentose or white-villose. Crowberries are acidic in taste, and have some form of bitterness; they`ve also got a light aromatic smell. Crowberries are packed with lots of water, antioxidants, manganese, fiber, copper, vitamins C and K, with loads of other nutrients.

Leaves

Black crowberry produces deep green leaves whose shape may either be elliptic or linear. The leaves are small and tough (ericoid) and measure anything between 4 mm and 8 mm in length. The blade is linear, needle-like, hollow, and the margin is curled downwards. The lower surface has a pale, hairy stripe.

Bees, moths, butterflies, and flies pollinate the flowers of Empetrum nigrum.

Fruits

Fertile flowers are followed by black succulent drupes measuring anything between 6 mm and 9 mm across. Each fruit of black crowberry encloses about 6 to 9 nutlets that bear resemblance to seeds.
