Started from a 4" pot 3 years ago, it is growing in morning sun, dappled sun to shade rest of the day, and it blooms profusely in late March into April. It has been evergreen in my zone 8 garden. The area is fairly dry as it is missed directly by the sprinkler system. It is spreading but not quickly or invasively. I like the lighter blue flowers on this than the Lucerne - they are much brighter. If you like blue eyed grass, this one is far superior to others I have tried.

We just got apiece of this plant last week and I haven't watered it yet. It has 3 flowers that close at night and open again in the morning, cute as a button. I'm planting it in the yard and expecting it to spread.
