Thanks, that would be it then, the Sleepy Orange. Funny, I just mentioned to the hubs the other day they might be Sleepy Orange & joked about how they ought to be called Speedy Orange as they act like they're jacked up on speed.
Melanie, I've never heard you mention having senna plants/trees. I have them on my list to get for here. I know the ones I had down south were pollinator magnets.
