How Big is a Flax Plant?

A flax plant typically grows to a height of 0.9 to 1.2 metres (3 to 4 feet) when cultivated for fibre, with slender stalks.

Flax (Linum usitatissimum) is an annual herbaceous plant whose size can vary depending on how it is grown. The provided reference describes key dimensions for plants cultivated specifically for their fibre.

Dimensions of Flax Plants

According to the physical description, flax plants grown densely for fibre have specific characteristics:

• Height: Plants average between 0.9 to 1.2 metres (3 to 4 feet) tall.
• Stalk Diameter: The slender stalks are typically 2.5 to 4 mm (about 0.10 to 0.15 inch) in diameter.
• Structure: These plants have branches concentrated mainly at the top.

Conversely, flax plants cultivated for seed are noted to be shorter and have a more branched structure, although the specific dimensions for seed flax are not provided in this reference.
