Fall over irises

Zone 20002 | cap40 added on May 15, 2017 | Answered

Hi, I have a variety of maroon irises that are mixed in with the lavender and dark purple irises. The purple irises bloom fine and look great, but the maroon ones always fall over. It's as if their stalks are too thin to support the flowers. Do they need to be planted deeper than then purple ones? I typically just lay the roots at the surface. Or is it just a weak variety? Any feedback welcome. Thanks!

It certainly can be due to a weakened variety.
I have had a few complaints of this issue this spring and we suspect cool rainy weather may be a cause also.

Iris are typically planted 12 to 24 inches apart and 4 inches deep.
