!! I'm late to the party, and it looks like the others have given you lots of good info, and ideas.....but, I will add this.....start slow, don't try for a huge bed of a hundred different cultivars. Decide on 15-20 that you like the color / form of, and plant those (there are very detailed 'planting instructions" found on various vendor's web pages, and at the AIS site, as well. Find out what works for you, in your soil, which class you like (size), and, how much time it will take you to care for them. Then, in two years, you will have first hand knowledge, to go with the "tips & tricks" you pick up here, and will be a confirmed "iris junkie", just like us
