This was the 2nd daylily I bought back in 1999 while walking through a local daylily farm. It was in full bloom and gorgeous. I'd never seen a watermark, and this large chalky one is very impressive against its wine color. It blooms early in April and again in July/Aug here in zone 9. Only peeve is that in-between bloom cycles it gets rust, so I've learned to cut all foliage back to 3" after 1st cycle and start a fungicide spray routine as well as putting granular Rose & Flower 3 in One by Bayer at its base. The new leaves don't have rust and it is ok for the 2nd bloom cycle.
