Any ideas which daylily this is?

It had a tag at one time. :)

It may be Hyperion. BEV
It is a lighter yellow here.

Thanks. I'll check it out.

It could be Constitutional Island. How big are the blooms? It's to dark to be Hyperion. It's a lemon yellow, not a gold. Constitutional Island is pictured below with Mabel Nolan.

That very well could be it. I looked at it on Smokey's Garden site. The plant came from a swap from Michigan.

Lol That's where I bought my Constitutional Island from. :-) It's a great daylily!

lol. That's probably it then. Small world. :-)

Thanks!

Your Welcome, anytime!
