Well, since many of you feel like knocking what I did, I'll give you more information.
My wife called literally as I was boarding a flight. My goal was to have something small in her room to make her feel better when she got back from the hospital. Yes, I realize I could have done it myself. I could have researched florists. I could have called the hotel directly but to be honest, I have no idea if it would have been international roaming charges. I was simply looking for convenience and speed to get something done for my wife. I wanted to make one call and have it handled while I was in the air.
Now, if you want even more detail. True, I'm not staying at the property. However, my wife is there running an event at the property that's hitting somewhere around (my guess without asking her specifically) 250 room nights. She's one of 2 decision makers there. I didn't mention this to the PLT concierge but for those of you looking for a soap opera I figure I'd add it

On top of all of that, she was injured ON THE PROPERTY so yeah, I had no problem taking up the offer of someone billing themselves as a concierge.
Long story short, I sent a private message to the SPG social media team on facebook. The professionally and quickly passed all the information on to the hotel. By the time I landed the flowers had been delivered and the concierge called me and left a message to make sure everything was satisfactory. I'm extremely pleased with the result despite the poor service from the concierge.
Finally, the question was essentially is this something we should expect from the concierge. It wasn't what would you do.
