French green beans can be either bush or pole, depending on the specific variety.
The term "French green beans" often refers to two distinct types: the broader, flat types often used for slicing "French style," or the very thin, delicate "Filet" beans.
According to the provided reference:
- The broad, flat green string bean that is thinly sliced French style is a pole bean.
- Most of the pencil thin Filet beans are bush beans.
This distinction is crucial for gardeners as it determines how the plants grow and the support they require.
Understanding Bush vs. Pole Beans
Beans are typically categorized by their growth habit:
- Bush Beans: These varieties grow compactly, usually reaching a height of about 1-2 feet. They do not require staking or support.
- Pole Beans: These varieties are vining plants that can grow significantly taller, often reaching 6-10 feet or more. They require support structures like poles, trellises, or fences to climb.
Growth Habits of French Bean Types
| Bean Type (often called "French Green Bean") | Growth Habit | Support Needed | Characteristics Mentioned in Reference |
|---|---|---|---|
| Broad, Flat String Bean (sliced French style) | Pole | Yes | Broad, flat green string bean |
| Pencil Thin Filet Bean | Bush | No | Pencil thin |
As highlighted in the reference, the broad, flat types commonly associated with "French style" slicing are pole beans. This means they will need a trellis or support structure to climb.
Conversely, the slender Filet beans, also often called French beans (haricots verts), are typically bush beans. These varieties grow more upright and self-supporting, making them suitable for smaller garden spaces or container gardening without requiring extra stakes.
Knowing the specific variety you are planting is essential to provide the correct growing conditions and support.
