Organic Blue Flax Seeds

Blue Flax is a lovely addition to any garden and grows effortlessly. It blooms perfect little 1″ flowers that open in the morning. We love the free-flowing look of these flowers. They can be sown thickly for a tall, dense 12″ garden border or interplanted with other flowers.

Blue Flax seeds produce a charming plant with edible seeds that can be used in bread, cereals, and more. We have produced this seed on our farm year after year for both seed consumption and seed sales. You can also use flax fibers to make linen materials.

Plants can withstand hot summers, poor soils and can even grow in part shade. Flax also works well for erosion control and attracts wild birds and pollinators.

Planting by Zones

Zones 9-10

• Flax is a warm-season crop that can be grown year-round in mild areas. In Zones 9 and 10, broadcast seeds in the cool of fall to establish over the winter or plant in early spring. Dainty blue 1″ flowers bloom from spring through fall. 

Zones 2-8

• Broadcast seeds in mid to late spring. Plants bloom from early to mid-spring.

Planting Flax Seeds

• Flax seeds are best planted by broadcasting seed into a full sun location with well-drained soil. Part shade is tolerated.
• Broadcast seed into debris-free, well-worked soil that has been deeply watered. Cover with 1/4″ of finely sifted soil.
• Seeds must remain moist to germinate evenly and quickly. 

Growing Flax 

• Blue Flax is easy to grow. It can be grown with little care in average to poor soils.
• Mulch heavily around your plants to help with weed suppression and moisture retention. 
• Flax is a perennial plant that reseeds easily.

Succession Planting Flax

• Succession plant every 21 days.

Growing Flax in Containers

• Flax can be grown in a container. Make sure your container is at least 10″ deep. Keep in mind containers will dry out faster because they have more surface area and less soil to hold onto moisture. 

Harvesting Flax  

• Blue Flax plants have edible seeds that can be used in bread, cereals, and more. Harvest when the seed capsules are dry; remove seed capsules from the plant and pinch open to collect the seeds.

Southern California Pro-tips

• In areas of Zones 9 and 10, flax is an easy crop to grow with a wide range of uses.
• Plant in full to part-sun during warm seasons and in the sunniest spots during cool seasons.
• During our hottest months of August, September, and October, plants can suffer from the heat. During this time, using shade cloth can help protect the plants from extreme heat. 

Companion Flowers/Crops

• Blue Flax can be sown thickly for a tall, dense 12″ garden border or interplanted with other flowers for a wild look. You can plant flax among cosmos, California orange poppy, and our Southwest wildflower seed mix for a meadowy feel. Blue Flax blooms earlier in the season than Scarlet Flax which blooms in mid-summer. Plant both for different colored flowers from spring through fall. Flax is effective for erosion control and also attracts wild birds and pollinators.
