Care & Size Guidance

Care & Size Guidance

Greenish yellow flowers in spring, turning to orange fruits in autumn, add to the attraction. They will grow in any soil but perform best in well draining soil and so long if they are never short of moisture.

The plant is cold hardy down to -3 degrees and evergreen, however it will require some protection from frost in winter with a horticultural fleece. If it collapses in an extremely cold winter, cut the foliage back in March and it will grow once again.

The Silver Shadow Flax is ideal for coastal gardens as the stiff leaves are fairly tolerant to windy conditions.
