Pollination

Self-fertile.

Growing it

Zones 3-8. A thornless currant x gooseberry hybrid - vigorous, productive and resistant to mildew and white pine blister rust. Larger than a currant, tarter than a gooseberry.

Will you get enough chill?

Jostaberry needs roughly 800–1600 hours between 32 and 45 °F over winter to break dormancy evenly. Check your area with the chill hours calculator. Low-chill breeding has pushed many varieties well below the figure here, so read the plant tag.

Chill and pollination are given at the fruit-type level; specific cultivars can differ. Values are typical ranges for home-garden planning.
