Linum perenne 'Appar'

Perennial flax (Linum perenne 'Appar') is a hardy species that grows in clusters from reddish-brown colored fibrous stems. They produce dainty but long lasting blue-tinged flowers that bloom from June to August and reach a height of 45 cm. The narrow, grass-like leaves are grayish green and are slightly fuzzy to the touch. It is a drought tolerant plant that prefers consistently moist soil and full sun, and it makes an attractive addition to rock gardens and perennial beds.

watering

Perennial flax (Linum perenne 'Appar') should be watered once a week in order to keep the soil slightly moist but not soggy. Be sure to water deeply and avoid light, frequent sprinkles which can cause the roots to stay near the surface of the soil. In the summer months, it can be helpful to water more frequently. During the summer months, check the soil near the plant's roots 1-2 times per week to ensure that it feels slightly moist but not wet. In the winter months, you may need to reduce watering to once every 2 to 3 weeks depending on your area's climate. If it rains more than a few times a week, you may need to eliminate additional watering entirely.

sunlight

Perennial Flax (Linum perenne 'Appar') requires full sun in order to thrive. It should receive at least 6 to 8 hours of direct sunlight per day during the spring and summer months. However, during the fall and winter, it may benefit from some indirect light. If grown in areas where the sun is intense, afternoon shade may be necessary to protect the plant from heat stress.

pruning

Perennial flax (Linum perenne 'Appar') should be pruned lightly in the spring or early summer. Begin by removing any dead or damaged branches, leaving the main stem intact. Once the dead wood has been cut, thin the entire plant, removing any excess branches that cross, crowd or lean heavily on the main structure of the plant. After that, any remaining shoots that appear to be out of shape or growing erratically can be clipped, as well as deadheading any spent flowers. Pruning too heavily may cause the seasonal growth of new stems to be reduced, so it’s best to remove no more than a third of the total plant’s height. Finally, lightly shape the plant as desired in order to maintain its compact and tidy shape. Perennial flax should not need to be pruned more than once per season.
