Daylily (Hemerocallis 'Rosabelle Van Valkenburgh')

This plant is very new to me. RVV was planted last Spring and produced 13 flowers last year. Very pretty! She initially bloomed from June 9- July 2nd, with 10 blooms. Then RVV rebloomed September 14-27 with 3 more blooms.
I'm pretty sure she was on the Greenhouse schedule from Northern Lights and will bloom more normally this season.
RVV has not gained or lost any fans so far. She started with four and four is where we are starting this season as well. I think it was too hot to get much of a pattern but some of my photos are hinting at one.

I have bought this daylily twice. The first time it did not survive its first winter here. The second time it survived both its first winter here and several more, so far.
I consider that it is only half-hardy here in my location and under my growing conditions. I suspect that it does not survive its first winter in cold winter zones easily.
It has not shown much in the way of flower patterning for me.

I planted this daylily recently in the Fall. Although it survived the winter, it appears to be struggling here. It's definately lagging behind others planted at the same time. It's down to one very small fan. Interesting to note, I am not far from Zoia's location.

2023 update…RVF barely bloomed this year. I only caught three flowers on camera, although I see a bud I didn't catch. At least the flowers are all nicely formed and no spots! However, she did put on two extra fans to end the season at six. I think the rebloom and rust last Fall took away some energy which the plant put into making more fans instead of blooming. Still, probably not super hardy here.
