World Premier has been a vigorous growing, strong blooming iris in my garden. Elegant flowers. One of the best

I highly recommend World Premier for hot climates. I'm in zone 9a. It's been blooming more than two months for me, and it still has a lot of tall stalks with big buds.

We had a late spring heat wave of a little over 100 degrees and almost all the other irises have fizzled out or look very sad.

This one is still standing tall and looking perfect. Very high bud count.

World Premiere's falls are a beautiful deep inky color--hard for me to capture accurately with the camera.
