Growing it
Zones 3-7, and unhappy in hot summers - give afternoon shade in warmer areas. Some US states restrict Ribes as a white-pine rust host, so check locally.
Will you get enough chill?
Currant 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.
