Plant Profile: Ribes alpinum

Alpine Current is a robust, rounded deciduous shrub belonging to the gooseberry family. It thrives in the mountainous regions of northern and central Europe and exhibits remarkable resilience to winter conditions. This shrub features distinct male and female plants, with only the females producing fruit. Most commercially available shrubs are male, as they are less prone to rust diseases.

This plant prefers a range of light conditions, from full sun to deep shade, and flourishes in average, moist, well-drained alkaline soils. It can tolerate rocky and clay soils and demonstrates some drought resistance once established. Typically, the shrub grows to a height and width of 5 to 6 feet, showcasing unremarkable flowers and vibrant green lobed leaves. The round red fruits appear only on fertilized female shrubs and are not suitable for consumption.

The foliage of this shrub extends down to the ground, making it an excellent choice for informal hedges, foundation plantings, or as part of a shrub border. It can endure heavy pruning and shearing without issue.

In terms of pests and diseases, Alpine Current may occasionally attract aphids, current bud mites, and scales. In humid, wet environments, it can be susceptible to leaf spots, rust, and anthracnose. Additionally, female plants can serve as an alternative host for white pine blister rust. Currently, all Ribes species are banned in North Carolina.
