I ordered from Schreiner's this year just to get the one iris I've been waiting for since 2009:
ALSEA FALLS
I also ordered another new intro:
FIDDLIN' AROUND

Then I received four additional rhizomes as gifts:
LIKE WOW
SILKEN TRIM
2 SUNRISE ELEGY
Edit: I have been using a 6-10-10 granular fertilizer that is really inexpensive (like under $3/box) at WalMart. It was in a green box and used to be called Pennington, but I think they changed the name last year. I haven't checked this year to see if they have it again, but they've had it for the last 5 years or so.
