Blackberry - Just the Faqs

When the plant antioxidant story became public a few years ago, one of the first fruits to rise to the top of the ORAC charts was the blackberry (Rubus ursinus).

A member of the rose family (Rosacea) and Rubus species of brambleberries (also called "caneberries"), the blackberry has become one of Oregon's most important fruit exports. Blackberries have an exotic nature to them perpetuated by the culinary fame of the famous Marionberry, a species of blackberry first bred from two cultivars of the Evergreen blackberry in Oregon's Willamette River Valley, Marion County. Marionberries have exceptional shape, aroma and taste that make them a worldwide favorite of gourmet chefs and specialty food manufacturers, paving the way for common use of brambleberries in today's kitchens.

Drooping with drupelets of goodness

As with other Rubus species (black and blackberries, loganberries, boysenberries), blackberries have a unique structure that actually contributes to their nutritional value ? it is an "aggregate fruit" composed of many individual drupelets, each like a small berry with one seed, surrounding a firm core called the receptacle. These individual drupelets contribute extra skin, seeds and pectin with dietary fiber value to the nutritional content of blackberries, making it among the highest fiber content plants known.

Where do blackberries grow and what characteristics do the berries have?

Blackberries grow wild and are cultivated in temperate zones from the mid-south US to near-Arctic latitudes of northern Canada and are cultivated mainly in northern US states, particularly Oregon and Washington State, and southern British Columbia. Blackberries are commercially grown on every temperate continent, including Africa and Asia.

Marionberries are the most widely cultivated blackberry specie in the world, especially favored as a popular fruit crop in many countries of Europe. Russia, Germany and Poland are major producers of blackberries. The state of Oregon harvests some 33 million pounds of blackberries each year, whereas the worldwide production is close to 1 billion pounds.

A tasty and long defensive history

The genus Rubus contains over 740 species as perennial, deciduous, woody shrubs with long vines ("brambles" up to 20 ft long) covered by firm thorns that made blackberry brambles useful as a defensive barrier along English land borders during the 16th century.

Rubus also includes roses and diverse other major fruits, including strawberries, apples, pears and peaches. While it may be difficult to see common characteristics among such diverse fruits and the blackberry, there is one important botanical similarity: the flower. All these Rubus plants typically have 5-7 white/pink petals around a central cluster of yellow stamens.

What is a "bramble" and is this the same as a "cane"?

A bramble is any plant belonging to the genus Rubus, of which the most commonly known-- and enjoyed-- are the red or black raspberry and blackberry, each having numerous hybrids. There are also some cross-cultivars between the red raspberry and blackberry, such as the boysenberry and loganberry.

Saying "bramble" is just a simple way to say "raspberries, blackberries, and related berry plants with thorny vines" Mainly in Oregon, these fruits are also called "caneberries" because they grow on woody bramble stems called canes.

What is it about blackberries that consumers most like?

Known as the "cabernet" of berries for their earthy, wine-like taste, blackberries are an easy and healthy addition to anyone's diet. This fruit has multiple macronutrients ? high dietary fiber (up to 20% by weight), carbohydrates, heart-healthy polyunsaturated fats (especially in its numerous chewable seeds), low overall fat content (
