Flowering CUrrant • Ribes sanguineum
Growth Habit and Environment
Red flowering currant is a deciduous shrub that typically reaches a height of 6 to 10 feet and has a similar spread. However, under optimal conditions, it can grow even larger. It has an upright to spreading, multi-stemmed growth habit. The branches tend to arch gracefully, giving the shrub a rounded and open appearance. The flowers give way to small berries that are initially green but turn dark purple-black when ripe. It is more commonly grown in regions with mild to cool climates and prefers full to partial sun. It can tolerate some shade, but flowering might not be as prolific in shadier conditions.
Seasonal Cycle
In early spring, before the leaves fully appear, the shrub bursts into a profusion of showy, pendulous clusters of flowers. These flowers are the main attraction of the plant and can vary in color from bright red to pink. The flowering period typically lasts a few weeks, and the clusters of flowers can be quite abundant, covering the branches and creating a stunning visual display.
In late Spring/early Summer, after the flowering period, small, round berries will appear from fertilized flowers. These berries are initially green but gradually turn dark purple-black as they mature. While they are not poisonous, berries are generally very tart, bitter, and mostly unpalatable.
As the days shorten and temperatures cool in Autumn, the leaves begin to change color, turning a radiant yellow before dropping onto the ground below. The berries continue to ripen, and the plant becomes an important food source for birds as they prepare for the upcoming winter.
Planting Tips
Select a location that receives full to partial sunlight. Red flowering currants can tolerate some shade, but they will produce more flowers in sunnier spots.
Ensure the soil is well-draining. Amend heavy or clay soils with organic matter to improve drainage. They can tolerate a range of soil types, but they generally prefer slightly acidic to slightly alkaline soils with a pH around 6.0 to 7.5.
Red flowering currants generally do not require heavy fertilization. A balanced, slow-release fertilizer applied in spring should suffice. Be careful not to over-fertilize, as this can lead to excessive leaf growth at the expense of flowers.
Prune after flowering to remove any dead or damaged branches and to shape the plant. This can also encourage better airflow and new growth. Avoid heavy pruning, as this can reduce flowering the following year.
