LONICERA CAERULEA, the HONEYBERRY, HASKAP BERRY, BLUE-BERRIED HONEYSUCKLE, or SWEETBERRY HONEYSUCKLE, is a honeysuckle native throughout the cool temperate Northern Hemisphere . It is a deciduous shrub growing to 1.5–2 m tall. The leaves are opposite, oval, 3–8 cm long and 1–3 cm broad, glaucous green, with a slightly waxy texture. The flowers are yellowish-white, 12–16 mm long, with five equal lobes; they are produced in pairs on the shoots. The fruit is an edible, blue berry about 1 cm in diameter.

The classification within the species is not settled. One classification uses nine varieties :
* Lonicera caerulea var. altaica. Northern Asia. * Lonicera caerulea var. caerulea. Europe. * Lonicera caerulea var. cauriana. Western North America. * Lonicera caerulea var. dependens. Central Asia. * Lonicera caerulea var. edulis, synonym: L. edulis. Eastern Asia. * Lonicera caerulea var. emphyllocalyx (also known as Haskap). Eastern Asia. * Lonicera caerulea var. kamschatica. Northeastern Asia. * Lonicera caerulea var. pallasii. Northern Asia, northeastern Europe. * Lonicera caerulea var. villosa. Eastern North America.
* Tundra * Borealis * Indigo Treat * Indigo Gem * Indigo Yum * Honeybee * Aurora * Wojtek * Atlaj * Nimfa * Berry Blue * Polar Jewel
According to research at the University of Saskatchewan , each variety can be distinguished by the size of berries, taste, and bush dimensions.
Haskap berry diversity
Lonicera caerulea is known by several common names
* Haskap: an ancient Japanese name of the Ainu people (also spelled phonetically as Haskappu, Hascap, Hascup); used today in Japan and North America * Blue honeysuckle: descriptive translation from Russian origin * Honeyberry: common in North America * Swamp fly honeysuckle: coined by botanists who found it growing wild in swampy areas of Canada
DISTRIBUTION AND HABITAT
The species is circumpolar, primarily found in or near wetlands of boreal forests in heavy peat soils. However, it also can be found in high-calcium soils, in mountains, and along the coasts of northeastern Asia and northwestern North America. The plant is winter-hardy and can tolerate temperatures below minus 47 degrees Celsius.

Haskap variety edulis has been used frequently in breeding efforts, but other varieties have been bred with it to increase productivity and flavor. In several haskap breeding programs, the variety emphyllocalyx has been the dominant one used.
Plants of many haskap cultivars grow to be 1.5 to 2 meters tall and wide, can survive a large range of soil acidity, from 3.9-7.7 (optimum 5.5-6.5), requiring high organic matter, well drained soils, and plentiful sunlight for optimum productivity. Lonicera caerulea plants are more tolerant of wet conditions than most fruit species.
Each berry has approximately 20 seeds that resemble tomato seeds based on their size and shape, but the seeds are not noticeable during chewing.
HARVEST AND USES
As a blue pigmented fruit, Lonicera caerulea contains polyphenol compounds, including cyanidin 3-glucoside , cyanidin 3-rutinoside , and peonidin 3-glucoside . Other phytochemicals present are proanthocyanidins and organic acids , including a high content of citric acid .
Over centuries, Lonicera caerulea has been used in traditional medicine in East Asian countries for a variety of therapeutic applications.
