The Garden of Eaden: THE BLUEBERRY

The blueberry is a very popular berrying fruit bush from the genus Vaccinium. It is a native to the American continent and is in fact one of only a few fruits native to North America.

Blueberries are a fruit rich in health promoting benefits. So many in fact that it is considered by many to be a 'super food'! To reinforce this belief, research from the University of Michigan Cardiovascular Center has found that blueberries can reduce belly fat, lower the risk of heart disease and metabolic syndrome. Furthermore, a study published in the 2009 Experimental Biology conference also said that a diet rich in blueberries function lowers cholesterol levels, improve glucose control and insulin sensitivity, and lowers the risk of heart disease and diabetes.

Blueberries and Native American Tradition:

For centuries, blueberries were gathered from the forests and the bogs by Native Americans and consumed fresh and also preserved. The North-East Native American tribes revered blueberries and much folklore developed around them.

The blossom end of each berry, the calyx, forms the shape of a perfect five-pointed star; the elders of the tribe would tell of how the Great Spirit sent "star berries" to relieve the children's hunger during a famine. Parts of the blueberry plant were also used as medicine.

A tea made from the leaves of the plant was thought to be good for the blood. Blueberry juice was used to treat coughs. The juice also made an excellent dye for baskets and cloth. In food preparation, dried blueberries were added to stews, soups and meats. The dried berries were also crushed into a powder and rubbed into meat for flavour Blueberries were also used for medicinal purposes along with the leaves and roots. A beef jerky called Sautauthig (pronounced saw'-taw-teeg), was made with dried blueberries and meat and was consumed year round.

The roll of the Blueberry in Thanksgiving:

During the seventeenth century, settlers from England arrived in the New World to begin colonies. Immediately, they set about clearing the land and establishing farms for they could not rely solely on supplies from England. But the land and the climate were far different from what they left behind. Many early attempts at farming failed.

In the winter of 1620, the Pilgrims established a settlement at Plimoth (spelt Plymouth today). Many perished during the first few months, but those that survived went on to build homes and establish farms. Their neighbours, the Wampanoag Indians taught the settlers new skills that helped them survive. They showed them how to plant corn and how to gather and use native plants to supplement their food supply. One important native crop was blueberries!

The colonists learned from Native Americans how to gather blueberries, dry them under the summer's sun and store them for the winter. In time, blueberries became an important food source and were preserved, and later canned. A beverage made with blueberries was an important staple for Civil War Soldiers. In the 1880s a blueberry canning industry began in the Northeast USA.

So, just how do you grow a blueberry bush?

Growing blueberries is really easy and can produce great results.

They prefer an acid soil in a nice sunny or semi shaded position.

And even if your garden soil is not acidic then you can try growing blueberries in containers using an ericaceous compost mix.

One top tip to remember is that like all acid loving plants, blueberries are best watered with rainwater whenever possible as tap water can make the compost more alkaline over time.

Pruning blueberry plants

Blueberry bushes don’t really require a lot of attention. But to ensure that your plant remains productive over many years you will need to prune them each spring around February or March, while the plant is still dormant.

Pruning blueberries is really straight forward once you know what you are trying to achieve. The idea is to ensure that your plant always has a good selection of productive young red stems with plenty of fat fruiting buds. These buds are much rounder than the vegetative buds so you can easily tell which stems will produce the most fruit. It’s the two year old wood that is most productive.

Cut back the just very oldest stems to ground level each year to encourage new stems to be produced - creating a constant process of rejuvenation. While you are pruning you should also aim to trim out any dead or damaged stems to help create a healthy open framework. Blueberries tend to send out some low horizontal stems close to the ground and these can also be pruned out too.

With regular pruning your highbush blueberry plants should remain productive for many years producing delicious fruit every summer. And with its attractive flowers and glorious autumn foliage your blueberry plant will make a stunning feature in your garden too!

Blueberry - family and species

Vaccinium is the family of all blueberries and includes more than 450 plants. . This plant grows wild around the world and there are many names given to different blueberries. For practical and commercial purposes we concentrate on three different varieties:

V. corymbosum. (Northern Highbush) Grow in the forests wild in North America and were used to cultivate the modern highbush or cultivated blueberry industry along with the V. Ashei.

V. ashei. (Southern Rabbiteye). You may be surprised to learn that blueberries thrive in the Southern USA. A variety called the Rabbiteye is named this because the calyx on the berry resembles the eye of the rabbit!

V. angustifolium. (Lowbush or also called "Wild blueberries." These dwarf bushes are very cold hardy, surviving in the wild as far north as Arctic North America. These Blueberries only reach a height of 1 or 2 feet. and include the low sweet Blueberry (V. angustifolium), which is found from the Arctic to Minnesota and the mountains of New York and New Hampshire, and the sour-tasting velvet-leaf Blueberry (V. myrtilloides), which is found wild throughout New England and west.

Blueberry common names

Many different names have been given to the numerous varieties of Vaccinium that produce edible fruits, such as Blueberry, Bilberry, Cowberry, Cranberry, Crowberry; Farkleberry, Lingonberry, Partridgeberry, Huckleberry (not the true Huckleberry, which is Gaylussacia), Whortleberry, and Sparkleberry to mention a few.

The cultivated Blueberry

For centuries decades, blueberries maintained popularity in the USA, with a thriving commercial business in the Northeast USA and Canada. An important step in the development of the highbush blueberry industry came in the turn of the century.

Efforts in the early 1900's by Elizabeth White and Dr. Frederick Coville to domesticate the wild highbush blueberry resulted in today's cultivated highbush blueberry industry.

They selected desirable plants from the wild forests of the Northeast USA and cultivated them to develop blueberries that could be commercially grown by farmers.

Their initial breeding work has resulted in the plump, juicy, sweet and easy to pick cultivated blueberry we enjoy today.

Without this cultivation work we would not have fresh blueberries in the marketplace as we do today.
