Description
Blanka closes the white currant season with very large crops of translucent ivory berries, ripening evenly along the strig from late July into August.
The berries are sweet and almost transparent, and the upright bush has earned the Award of Garden Merit. It is also reported resistant to anthracnose and more tolerant of a dry spell than an ordinary currant.
Blanka is an established Slovak cultivar, not a recent introduction. The cross dates to the 1960s and the cultivar entered the Czechoslovak state assortment in 1977, giving it nearly fifty years of garden and commercial use behind the name.

Additional Notes
- Grower’s Insight: Blanka’s heavy crop needs spring feeding, steady water during berry sizing, and a full frame of nine to twelve canes.
- Regional Insight: It tolerates temporary drought and indifferent soil, but summer heat still limits currants more than dry ground does.
- Currants host white pine blister rust and remain restricted in parts of the United States. The rules apply to the plant rather than to the cultivar, so check your county and state before ordering.
