Czech 17 (A.K.A. Berry Blue) is a highly vigorous variety of Haskap. At maturity, plants of this variety can top out at a height of 5 to 6 feet with a spread of 3.5 feet wide. The medium-sized fruits have a firm flesh. Healthy, mature plants can yield as much as 10 to 15 pounds of berries. This variety has a good flavor that is excellent for juicing and making deserts. Flowers of Czech 17 are abundant and appear over a long period of time, which makes this particular variety an excellent pollinator for all other Haskap varieties. The fruiting period is also more prolonged--sometimes 6 weeks, or more--beginning in early summer timeframe.
