Some Irises survive and reproduce well in my garden. Others I just can't get to grow. Superstition is one of my best growers. Liason I have tried several times with no luck. If a description says "Vigorous" or "Disease Free Foliage" "Sturdy Stems" etc. is this a good clue? Whereas if no mention is made it might be one of the peaky ones?

I would say that is a good clue but not an absolute. There is a very popular award winning iris which we discussed at a UIS meeting. Several friends said that they had eliminated it because it wouldn't grow. This year there was a fabulous specimen at a UIS show. The grower said it flourished in his Utah garden. Go figure

What's good for you ,may not be good for me. So I guess I'd agree with Paul. If it say's vigorous, or rampant, or strong, it probably is....where ever that grower is ! Best to go by local input from others in your area, if you can. If you can't, ask around on the forums for info from those in the same zone, or areas of the same frost free days.......Arlyn

I never worry about whether an Iris will do well for me or not. If I like it, I get it. In all the (forty-something-omigod) years that I've grown Irises, I've only ever had one variety fail. For the life of me I can't remember it's name. It was a Ghio Iris -- I remember that. Anyrate -- the only way that you'll know if an Iris will do well for you is to try it. I've found Irises to be very forgiving plants. If they can possibly get along, they will.
