The taste, ingredients, and uses of Japanese Wineberry<\/a><\/li><\/ul><\/nav><\/div>\n\nThe Japanese Wineberry ( Rubus phoenicolasius<\/em> ) belongs to the rose family (Rosaceae) and the genus Rubus<\/em>. The species name phoenicolasius<\/em> is made up of the parts phoenix<\/em> (= purple-red, fox-red) and lasios<\/em> (= densely hairy, shaggy) and alludes to the hairiness of the shoots. Japanese Wineberry is closely related to blackberries ( Rubus fruticosus<\/em> ) and raspberries ( Rubus idaeus<\/em> ).<\/p>\nSome sources name the Japanese Wineberry berry as a hybrid between blackberry and raspberry, comparable to loganberry or tayberry. However, this crossing should have taken place naturally, i.e. without human intervention. As the name suggests, Japanese grapes are found in Japan but are also native to Korea and China. It has been used by people since the end of the 19th century and has also been cultivated in this country since the second half of the 20th century.<\/p>\n
It grows as a rampant 2-3 meter high and equally wide, upright, and deciduous shrub with overhanging or prostrate side shoots. There are only a few thin spines on the red-brown rods. Instead, the shoots are dense and bristly covered with red glandular hairs, which gives the plant an exotic, but also extremely elegant appearance. The dark green, three to five-fold leaves are about 10 centimeters long and are flocked white on the underside. The Japanese grape, like its relatives, forms root runners and can spread so well.<\/p>\n
Old plants can take up a space of 16-20 m\u00b2. The pale pink flowers of the Japanese Wineberry are in small clusters. The flowering period extends from June to July. The flower buds, just like the shoots, are red in color and have sticky, bristly hairs. The initially apricot-colored, hemispherical aggregate drupes ripen from July to August, then turn deep wine-red and feel slightly sticky.<\/p>\n

<\/span>Planting Japanese Wineberry<\/span><\/h2>\nFor domestic cultivation there is no subdivision of the Japanese grapevine into varieties, it has probably not been cultivated until now as a rare exotic berry. Sometimes it is offered as a hybrid berry or among blackberry varieties, but strictly speaking, the Japanese Wineberry is a species of its own. Japanese grapes are not picky about their location, as long as it is a little sheltered and warm.<\/p>\n
Similar to blackberries, they grow on all types of soil, as long as no waterlogging forms. The ideal location for Japanese grapes is sunny to partial shade on well moisture-retaining, moderately nutrient-rich soils with a calcareous to neutral pH value. Either you let the vigorous bushes grow wild or you guide the Japanese grapevine on climbing aids or trellises along walls and fences. You can also let them grow as a fruit-bearing hedge.<\/p>\n
The Japanese grapevine is planted in the spring after the ice saints, as the young plants are still a bit sensitive to frost in the first few years and the plants that are barely rooted can be damaged. So it can form strong roots by the first winter and already establish itself somewhat. Before planting, the soil should be enriched with organic material, such as ripe compost, and large areas should be dug up. Individual Japanese grapes should be placed 150 cm apart so that they can develop well. When planting, dig a deep hole and place the Japanese grapevine in it so that it sits about 10 cm deeper than before. The shoot buds on the root neck are covered by soil and can develop well.<\/p>\n

\nWhen planting grapes in pots, the planter should hold at least 10-15 liters and the shrub should be moved to a larger container every year. For planting in pots, we recommend nutrient-rich potting soil, such as our Plantura organic universal soil. It provides young plants with a basic supply of all essential nutrients and, thanks to the high compost content, promotes root growth and soil life.<\/p>\n
Tip: To prevent Japanese grapes from spreading excessively in the garden, you should use a root barrier about 40 cm deep when planting. The flat roots only spread within the barrier by means of the root runners.<\/div><\/div>\n
