Ecological habits: not cold-resistant, avoid extreme heat, not resistant to wet and waterlogging, not resistant to fertilizer, like sandy soil.

Flowering: blossoms in spring or autumn.

Garden use: flower bed, flower border, cut flower or potted flower cultivation.

Species identification: same genus species-flax (blue flax) L. perenne has slender stems, drooping top tips and blue flowers.

The plant height is 20cm to 30cm, the flower is blue, much branched, the florescence is long, the management is extensive. The effect of Yiyan stone garden, flower border, potted plant and clump planting is better. The common growers in the same genus are white flax n. Repens.

Planting and propagation methods and cultivation management of blue flax

Plant name: blue flax; Latin name: Linum perenne L; alias: perennial flax, blue flax, perennial herb.

Propagation and cultivation: mainly sowing and reproduction. It can also split. Sowing and breeding methods: can be divided into spring sowing and autumn sowing. 1. Spring sowing: first wash the seeds with detergent or laundry detergent, soak them for 24 hours, freeze the seeds in the refrigerator for 24 hours, thaw the seeds with fine sand, spread them on a clean ground to air, cool and relax, the seedbed should first be disinfected with 1500 times potassium permanganate solution, and then sow the seeds on the seedling bed soil after the water permeates, covering 2 times the diameter and thickness of the seeds. The pot should be covered with transparent glass and covered with a newspaper with uniform font to shade the sun. Nursery bed seedlings need to be covered with film, high-pull sunshade net; after a week, the seedlings emerge neatly, then remove the glass or film, and gradually remove the sunshade net; after the seedlings have 4 true leaves are stronger, divide the seedlings. After dividing the seedlings, the seedlings were cultured indoors or in the shed for about half a month, and then placed in a well-ventilated place for 3-5 days, then the seedlings were refined out of the room, and the seedlings could not be planted in the field until half a month later, and the row spacing of the seedlings was 25~30cm. Because the seedlings are delicate and easy to be covered by weeds, it should be ploughed and weeded frequently, and fertilization should be applied thinly for many times. 2. Autumn sowing: autumn sowing is generally carried out from late September to mid-October, and it is sowed on the open field seedbed, which is generally 10m long and 1m wide. If the seeds are sown or sowed on a flat and fine seedbed, the sowing density can be relatively small, so there is no need to transplant.

Blue flax can also use the method of ramet reproduction, combined with transplanting, but with this method, the reproduction is easily limited by the seedling source.
