They could but no guarantee. Good luck with your sale.

Im in z5 as well., Its pretty early still here so if I had to guess they would. Ive been to local sales that they did the same thing and they had blooms.

Do you have pics of them blooming? Get a stick and tape the picture to the stick and put it in the pot. You can buy Popsicle sticks for something like 40 at the dollar store. It will help your sale if they are not blooming or if you get only one bloom and the rest of the week you do not have blooms.

Better prepared than wish they were blooming.

I'm in my bedroom as I write this, looking at all the potted up daylilies that I've received from Florida this spring (too cold to put outside until tomorrow - my husband will be so happy that it's finally warm enough to have his bedroom plant free!). Fern Stone, a 3 fan division, bloomed yesterday. Volaris, a 1 fan division, and Apple Blossom White, another 1 fan division, both are sending up scapes. Ditto for Kaleidoscope Queen and Randall the Runner (I'm only letting the plants that are growing well bloom - I know I broke scapes off a couple others that tried to bloom before they had recovered from being shipped across the country in a box). So I think that most of your daylilies are going to bloom this year! Though perhaps the flowers will not be full size. But that just means that your customers will be even happier with them next year.
