This Iris is one of many transplanted from my mother-in-law's yard when we first moved in seven years ago. We planted them along the driveway, but they never got enough sunlight. We did get flowers, but they were few and purple. Not that anything is wrong with purple.
Two years ago, I moved them to a sunnier location and, not only do they bloom earlier, they are now yellow instead of purple. I guess it might have to do with the PH of the soil, I really don't know. They are a whole lot happier in their new location.
