No, black currant is not a vine. It is a deciduous shrub.
Blackcurrants (Ribes nigrum) are well-known for their tart, dark purple berries and are a popular addition to many gardens. Despite sometimes being trained or supported, their fundamental growth habit is that of a bush, not a climbing vine.
Understanding Blackcurrant Growth Habit
Blackcurrant plants are characterized as deciduous shrubs, meaning they shed their leaves annually, typically in the autumn. These robust plants develop multiple woody stems directly from the ground, forming a self-supporting bush structure rather than needing to climb or sprawl along a support system like true vines.
Key Characteristics of Blackcurrants
- Growth Form: Blackcurrant bushes grow upright, reaching heights of up to two metres (approximately 6.5 feet). Their sturdy stems do not twine, cling, or root along the ground in the manner of a vine.
- Foliage: The shoots are adorned with distinct three- to five-lobed leaves, roughly the size of a human hand. These leaves contribute to the plant's bushy appearance.
- Fruit Production: In summer, these shrubs become covered with clusters of dark purple berries, which are highly valued for their nutritional content and flavour.
- Woody Structure: Unlike the flexible, often sprawling stems of many vines, blackcurrant plants develop a strong, woody framework that supports their own weight and fruit load.
Shrubs vs. Vines: A Quick Comparison
To further clarify, let's look at the fundamental differences between shrubs and vines:
| Feature | Shrub (e.g., Blackcurrant) | Vine (e.g., Grape, Ivy) |
|---|---|---|
| Growth Habit | Multi-stemmed, woody, self-supporting upright growth | Climbing, trailing, or sprawling; often requires support |
| Stem Type | Rigid, woody stems | Flexible, often slender stems, can be woody or herbaceous |
| Height Support | Grows to its full height independently | Uses tendrils, aerial roots, or twining to climb |
| Longevity | Typically perennial, long-lived woody plants | Can be perennial or annual, growth often extensive |

Cultivating Blackcurrant Bushes
Given their shrub nature, blackcurrants are typically grown as freestanding bushes or can be trained into various forms suitable for smaller spaces, such as cordons or fans, but these training methods do not alter their inherent shrub characteristics.
- Planting: Blackcurrants thrive in rich, well-drained soil and prefer a sunny or partially shaded location.
- Pruning: Regular pruning is essential to maintain plant health, encourage new growth, and ensure good fruit production. This involves removing older, less productive stems to make way for younger, more vigorous ones.
- Support: While blackcurrant bushes are self-supporting, some growers might use stakes to help young plants establish or to support heavily laden branches to prevent them from touching the ground, but this is not a requirement for their fundamental growth as it would be for a climbing vine.
