Grow Sisyrinchium once, and the common name of Blue-Eyed Grass will make complete sense. The leaves of this low growing perennial are quite grass-like, and in summer it comes alive with very delicate blue flowers that seem to appear out of nowhere. Below are some top tips on how to grow Sisyrinchium.

When I Get My Seedling Home
Keep seedlings under very bright light to prevent legginess. Artificial lights are ideal, but a bright (ideally, south-facing) room will work for the short term. You may have to pot on seedlings more than once before they go out to allow for root growth. This is done by transplanting them into a slightly larger container with enough additional soil to keep the container mostly full. Keep the soil moist by daily watering and allow for free drainage so the plants are never sitting water.
Transplanting
Do not transplant outside until daytime temperatures are steadily 10°C (50°F) or warmer. This may mean keeping seedlings indoors for up to a month. The plants should not require any fertilizer until transplant time.
Growing
Transplant after last frost into average, well drained soil. Sisyrinchium grows well in most situations, but it excels in moist, well-drained, fertile soil with pH of 6.5 – 7.8. This is one of the few plants that prefers partial to full shade.
