Growing scarlet flax: Grow scarlet flax in full sun in any garden soil, preferably somewhat low in fertility. They perform best in cooler climates. Plants will tolerate mild frosts; in colder climates they can be planted in the fall for late spring bloom. Otherwise, sow in place as soon as the ground can be worked in the spring. Space 4 to 6 inches apart. Water during dry spells. Each plant blooms approximately 4 to 6 weeks. For all season display, reseed at 4- to 6-week intervals.
Propagating scarlet flax: Start new plants from seeds. For earliest bloom in most locations, start seeds indoors 6 weeks prior to outdoor planting. Grow in peat pots to aid in transplanting. Seed germination takes 5 to 12 days at 60 to 70 degrees Fahrenheit.
Uses for scarlet flax: Scarlet flax is a good addition to wildflower or meadow gardens. Grow it in clumps in borders or beds and in mixed plantings such as cottage gardens. Plant it also in rock gardens.
