There's no pic so we don't know what kind of succulent you're asking about. Some succulents root more slowly than others. Some are unlikely to produce roots outside of their growing season and their growing season may be when days are shorter rather than longer. Without more info I think we can only advise you to be patient and continue waiting for roots.

Congratulations Deva:)!

I‘m really curious to know what succulent isn’t growing roots yet. Especially since it was the main succulent in your bouquet.

Man! I attached 2 photos last night! I’ll try again when I get home.

Looks like there is a root forming--that tiny pink spot. So give it a couple more weeks and you should see more. Warmer (warm but not hot) weather will speeding things up.

The stem should have been cut clean and flat; pulling off more leaves to get a good clean cut and a bit of bare stem is helpful. But not now--just for future reference.
