June Wedding - No Flowers

So I’m already having to deal with the possibility of postponing my wedding on June 6th. If we postpone, we are waiting a year....potentially June 12, 2021. With the uncertainty of the wedding, I contacted my vendors. I texted my florist explaining that there was a chance that the wedding would be postponed. She responded saying that even if the wedding was still on, she didn’t think she’d be able to pull it off.


A little background info is that she is a former student of mine who has been trained in floral design and I was using her so that she could build her portfolio and get some real life experience. I begged to give her money and I offered to draft a contract on several occasions... no money was ever exchanged and nothing was signed. I’ve had a bad feeling about this for a while and I know it’s my own fault.
So now, my question is how do I get flowers this late in the game when all “nonessential” businesses are closed in my area until further notice? Can I order from Costco? Do I contact the florist my local grocery store ? The wedding still might not happen, so do I even worry about it now?
