    I grow flax at the base of my clematis trellis, to provide shade for the clematis roots. It blooms prolifically, and reblooms repeatedly if I deadhead it. The foliage is lacy and attractive, and the seeds are easy to harvest. I suggest putting a cup or bowl beneath the seed pods and clipping off the stems, as the paper pods tend to shatter at the lightest touch. Good candidate for winter sowing and direct seeding.
