Hi Maryl,
to this wonderful Iris forum and family !!! You will love it ! We have so many wonderful friends who always ready to help.... I am new to Iris, I have very few Irises for several years but only from boxstore and friends/neighbors and then I found this wonderful community
....
I live in North Texas so I think our weather is pretty close, I don't think I ever lost any Iris to winter (short winter it is) but lost few to wet Spring, when the rains just won't stop and the weather is not hot enough to dry the ground in between... I buried mine just like everyone suggested with most of the rhizome showing...I hope your Irises grow healthy and beautifully and share some photos...I hope some of my new ones will bloom next Spring...
Have a wonderful morning everyone
