Linum campanulatum is a perennial plant belonging to the Linaceae family. Linum campanulatum reaches on average 10–30 centimetres (3.9–11.8 in) in height. The short stem is perennial, woody and glabrous, with long herbaceous annual branches. Leaves are alternate, up to 4 cm long and 1 cm wide. The shape of lower cauline leaves is quite variable. Usually they are obovate-obtuse, but in some cases may be spatulate-lanceolate. The upper cauline leaves are gradually reduced in width to become almost linear.
It has to be watered about 3 times a week in summer and every 3-4 days the rest of the year. In any case, if in doubt, the humidity of the soil should be checked, for example by inserting a thin wooden stick all the way to the bottom. If it comes out practically clean, we will not water.
The plant does well in infertile soil, fertilized in the fall with a half and half blend of balanced fertilizer and high-quality compost. Remember not to go overboard as overly rich soil can cause leggy growth.
Average to sandy well-drained soils are preferred. Flax does not do well in heavy clay or in wet conditions. If direct seeding, rake soil and broadcast seeds, raking in and tamping down to make good soil to seed contact.
