A year ago I purchased Daylily (Hemerocallis 'Grape Ripples') but I have a couple with the labels missing so I'm not real sure of identities. The bloom on this one is @ 4 1/2" across and the scape height is @ 10" which doesn't match the 24 " that the database shows but could that be due to cultural conditions? I'm not the best when it comes to taking care of my plants sometimes. I also bought 'Little Missy' at the same time but photos of that one show very white petal edges so I don't think it's her but looks more like Grape Ripples to my eyes. Any suggestions?

The shape looks off to my eyes.

I think it is Grape Ripples.
Your flower will probably get bigger and taller as it gets established.
Your picture does look kind of triangular, but I think it just looks like that because of the heat.
