I have a question....what would make a Spuria iris grow sideways instead of upright? I planted 4 varieties last fall...3 are upright, but one is leaning way to the left, at about a 45 degree angle. It is in its first season, so has no buds, although a few of the others do. Is there anything I should do now, or should I wait til the fall and dig it up and replant? Thanks! :0) Phyl
