Blue flax is a clump-forming perennial with wiry, grass-like leaves and stunning violet-blue flowers that bloom in the summer. Growing to 50 cm tall, Blue flax is a very drought-tolerant and low-maintenance plant that thrives in poor soils. A fun fact bout this species: Flax is the plant used to make linen, and the seeds are edible (and very nutritious) once cooked!

When selecting non-invasive plants for your garden, be sure to look for those that are suitable for your location, including moisture requirements, hardiness zone, and avoidance of known bear attractants among other factors.
