Thank you both so much for your replies. I'm just kind of bummed because I've been watching and fussing over them for 3 years now and getting my hopes up that I could finally see them bloom in all their glory. And they're such a pretty blue and I don't have much blue in my yard. But it's not as bad as the year I spent all summer watering these plants that got huge and thrived and then realized they were weeds! But I will check on them first thing every morning and maybe I'll be surprised.
Thank you.
