Flax has been grown in England for centuries and is still farmed in Europe today as a source of fiber to make linens and rope. Try to pick a flower stem and you will understand why. 'Sapphire' is a tireless performer, especially when given a proper growing environment; light, well-drained soil and full sun are best. All Flax species abhor 'wet feet', especially when it is a result of poor winter drainage, so make sure you provide very well-drained soil. Once established, it will be quite drought tolerant. This is a great plant for gardens, since it tolerates the summer heat very well.
