All of these varieties are hardy down to zone 3, resistant to white pine blister rust and very high in vitamin c. Currants are self-fertile, but research suggests that planting more than one variety results in better yields. They grow in full to partial sun.
 
Black Consort is an old variety with an upright, multi-stemmed form that bears fragrant flowers in spring and brilliant orange red foliage in fall. Clusters of medium-sized, black, sweet-tart musky fruits ripen in late summer. 
Ben Lomond is the first bred from the Scottish Crop Research Institute and is a very heavy producer of large berries that is also resistant to white pine blister rust. They are among the easiest to grow and are said to be the highest-quality black currants in the world. The bush is compact, upright to 4-5 feet tall and easy to grow and prune. Reliably self fruitful, but best production comes with another variety of black currant for cross pollination. Ripens mid-July. Likes a sunny position but shelter from wind and late frost; moist but well-drained soil. Harvest from late July.
 
Red Lake has large and juicy red berries that ripen in the middle of summer with intense flavor that is ideal for making preserves. Although they are more tart than their black counterpart, they can still be eaten fresh and are considered the tastiest of the red currants. Be mindful, they are more attractive to birds.
