Scarlet Flax is an annual flowering plant that will grow quickly, bloom profusely for 4 to 6 weeks and later die with the first killing frost. The plants will produce clusters of deep, ruby-red colored flowers that span 1 to 1.5 inches in diameter.

Each plant will grow to a mature height of about 12 to 36 inches tall, spreading roughly 18 inches wide. The plants, once established, are pretty drought tolerant and won’t need much tending. The seeds of the Flax plant will glisten because of their high oil content. You may not know that Flax is the source of linseed oil, which is great for polishing and refurbishing wood.
