Description
They have simple elliptical leaves that are alternately arranged along the stems with dots. The plants generate urn-shaped flower clusters that eventually bear fruit. When ripe, the fruits have a dark indigo to black colour and are genuine berries with numerous tiny seeds.
Varieties
The main types include:
Highbush (Vaccinium corymbosum): This variety of blueberry is the most prevalent and fruitful. The varieties “Bluecrop,” “Blueray,” “Herbert,” “Jersey,” and “Meader” are suited for cold winters.
The hybrids of Viburnum virgatum, Viburnum corymbosum, or Viburnum darrowii known as Southern highbush are regarded as being fairly difficult to grow, but certain cultivars, such as ‘Emerald,’ ‘Windsor,’ and ‘Springhigh,’ are popular in Southern gardens.
Lowbush (Vaccinium angustifolium) bushes can grow as far north as zone 3. They are well adapted for the coldest conditions. They grow around one foot tall with a creeping spread, which is very distinct from other varieties.
Half-high blueberries, which include types created by mating highbush and lowbush species, are a more recent breeding development. The cultivars “North Country,” “Northblue,” and “Northland” are all well-liked varieties.
Vaccinium ashei was the old classification for rabbiteye. It is predominantly grown in the Southeast of the United States. ‘Woodard,’ ‘Powderblue,’ and ‘Delite,’ ‘Brightwell,’ which is another fine late-bearing variety, are recommended types.
Uses
Blueberries can be cooked in a number of pastries and are frequently consumed fresh as a dessert fruit.
Nutrition
Blueberries are made up of 14% carbs, 0.3% fat, 0.7% protein, and 84% water. They have moderate levels of dietary fiber, vitamin C, and the critical mineral manganese, but low levels of micronutrients. The glycemic load per 100 g is 6, 240 kJ, which is a relatively low amount of dietary energy.
Cultivation
In full sun, blueberries thrive. Partial shade is tolerated by plants, but excessive shadow makes them produce fewer blooms and less fruit. Avoid regions where trees are present. Trees cast an excessive amount of shade, compete with plants for water and nutrients, and obstruct airflow around plants.
