Black Satin

Black Satin blackberry is old semi-creeping variety. It has powerful long canes (up to 5-7 m long) without thorns. Canes have dark brown color. Up to 1,5 m this cultivar grows upward, after will begin to creep. Branches grow very quickly (up to 7 cm daily). They make a lot of laterals. Black Satin requires constant molding, cropping and laying on a trellis, otherwise fruit do not receive enough light and nourishment, become smaller and cannot fully ripen.
Flowers are pink when opened, after a few days they fade to white. Berries are collected in brushes of 10-15 pcs, the number of brushes is very large. The flowering begins in early June. Blooming period is very long.
First berries ripen in late July or early August (vary from weather conditions and region), harvest season ends until late autumn. Due to the very long harvesting, some fruit will not have time to ripen. 
Berries are medium size (from 3 to 4 g), at the ends of the canes - much larger, up to 7-8 g. Fruit are beautiful, have rounded elongated shape and glossy black color. Unripe berries have an acid taste, while in appearance they look ripe. Ripe berries are very soft, juicy and cannot be transported. Black Satin fruit must be harvested every 3-4 days, otherwise the fruits are easily affected by grey mold.
The yield of Black Satin is high, up to 10-15 kg per plant, and with right agricultural technology up to 25 kg.
Black Satin can be compared to Thorhfree, both varieties are very similar to each other. Like Thornfree, fruit of this variety can be used for wine production.
The Black Satin variety has good frost resistance up to minus 18 C.
