Czech 17, also known as Berry Blue is super vigorous. The plants will grow to a mature height of 5 to 6 feet and 3.5 feet wide. The medium fruits are firm and will yield 10 to 15 pounds. The flavor of the fruits is good, but this variety is best for making deserts and juicing. An abundant amount of flowers are grown and appear over a long period of time, making Czech an excellent pollinator for all Haskap cultivars. Fruiting occurs for more than 6 weeks beginning in the early part of summer.
