I didn't buy those, all the iris from my Walmart looked totally dried up. I usually do though, & have had good luck on the whole with their being what they were supposed to be, etc. I went to Van Bourgondien's web site though, & the german iris I checked all said sun to part sun with spring bloom or spring/fall if reblooming. The siberian iris said June bloom, but mine are blooming now. If the rhizomes looked healthy, they should come up, I would doubt they would bloom this year though.

I siberica is fine with some shade during the day. It likes a fairly rich soil that holds moisture. Too much shade seems to affect flowering the following season. Expect stems 2-2.5 feet and a reasonably long flowering period. Usually a well-mannered plant...doesn't sprawl or go rampant.
