Iris Information

Learn More About Iris

If you need a speaker for your horticulture club

Let us know. We offer basic and advanced iris programs. Margaret is a prolific photographer, so there are lots of pretty pictures to “ooh” and “aah” over. Patrick loves to hear himself speak, and it gives him another excuse to leave the weeds in peace.  If Patrick is not the right person, we can connect you with someone who has the knowledge you are seeking.

‘I’ve have ordered a large number of iris over the past couple years from Cascadia. Patrick and Margaret have been stellar to work with. I’m very picky and they have been able to accommodate my requests and also keep me very well educated on iris culture. All of their iris I ordered were healthy and strong—every one came back the next year. The pictures of their iris are very accurate as well—no weird color treating. I will continue to work with CIG in the future! Thank you Patrick and Margaret!’

Jeremy M. Overland Park, KS

"I have purchased Japanese Iris from Cascadia Iris Gardens for the past 3 years. I have always received very healthy iris, whether I purchased them spring or fall. I have never been disappointed. That is why I always come back. I am looking forward to seeing their 2018 selection."
