    One of the all time great daylilies. Wonderful fragrance, cheerful flowers, vigorous plant, loads of blooms.
    One of my first when I started growing daylilies in 1972, and still will not be without it.

The south, front area is too hot (partly because I don't water it). Dug them up a couple weeks ago and left them in a tray of water until today (8-14-2021). 15 fans. Gave 5 to Kara K. previous Friday. Planted 5 fans today in front side yard above downspout by living room windows. Gave rest of the fans to Becky and Maggie at supper at The Metropolitan today.
