‘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!’

"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."
