How to Plant Linum Perenne

Overview

Linum perenne, also known as perennial flax and blue flax, grows to be about 1 to 2 feet in height and width. It has blue flowers that bloom in the summer and fall months. It is a perennial plant that usually is hardy in zones 4 to 8, depending on variety. It can be planted anytime of the year in zones 7 and 8, but is best planted in the spring (before growth) or in the fall (after blooming) in zones 4 to 6.

Step 1

Select an area to plant linum perenne that is in full sun to partial shade. It will bloom best in full sun but also will grow and bloom well in partial shade.

Step 2

Create a planting bed that is well-draining. Loosen the top 12 inches of the soil bed. Evenly mix in 3 or 4 inches of organic matter such as compost or peat moss.

Step 3

Dig holes for the linum perennes, spacing them about 12 to 18 inches apart. The holes should be twice as wide but the same depth as their current containers.

Step 4

Remove the plants from their containers. This is easiest when the soil is slightly wet. Removing the soil around the roots isn't necessary.

Step 5

Set the plants in the holes and backfill with soil. Firm down the soil with the palm of your hands.

Step 6

Water the planting site with about 1 to 2 inches of water.
