Overwintering

In colder regions, tie the leaves together to protect the crown from snow and ice buildup. If you live in a very cold area, move the container into a sheltered, frost free spot for the winter.

In containers

It grows very well in containers, but you should use a pot at least 15 to 20 gallons to accommodate its large root system.

Pair with plants that have similar water needs to ensure everyone stays happy in the same bed.

Bonnes associations

• Hebe — These shrubs provide a nice textural contrast and share similar coastal growing requirements.
• Carex — Sedges create a soft, grassy base that complements the rigid, upright form of the flax.

À éloigner de

• Small delicate flowers — The aggressive root system and large size of the flax can easily crowd out smaller, slower growing perennials.

Espèces similaires

• Mountain Flax — It is a smaller, more arching relative that fits better in tight garden spaces.
