Yes, sorrel can multiply, though the specific method and degree of spreading depend significantly on the type of sorrel.
Different varieties of sorrel exhibit distinct growth habits when it comes to spreading and multiplication:
- Common Sorrel Varieties: Many common types of sorrel tend to form contained plants, typically occupying a space comparable to that of a large broccoli plant. These varieties primarily multiply through seed dispersal. They will not spread vegetatively through roots or runners. To prevent these types of sorrel from spreading, it is essential to prevent them from flowering and setting seed.
- Sheep Sorrel: In contrast, sheep sorrel is notable for its ability to spread aggressively via horizontal growing roots. This vigorous spreading characteristic makes sheep sorrel a suitable choice for areas where you desire a spreading groundcover or a more expansive perennial presence, such as in hedgerows, food forests, or other perennial growing areas. It can also spread by seed.
Here's a summary of how different sorrel types typically multiply:
| Sorrel Type | Primary Multiplication Method(s) | Spreading Tendency | Notes |
|---|---|---|---|
| Common/Other Sorrel Varieties | Seeds | Low (if managed) | These plants generally remain contained and will only spread if allowed to flower and produce seeds. They do not spread through root systems. |
| Sheep Sorrel | Horizontal Roots, Seeds | High | Known for spreading actively through its root system, colonizing areas. This makes it ideal for covering ground in perennial systems like hedgerows and food forests. It can also multiply through seed dispersal. |
Understanding these different growth habits is crucial for effective management, whether you aim to contain sorrel's growth or encourage its spread in your garden or landscape.
