"Will they transplant okay or are they fussy? Will they tolerate our May temp swings or just be careful with any frost?"
They transplant extremely well. As for temperature swings they love warmth for best growing and flowering. If you set them out while it is still cool (air temp and ground temp) you're not giving them any kind of head start, they'll just sit there or grow extremely slow. It's best to time your seed starting so they germinate in warmth, get their true leaves then pot up to a bigger pot (or start them in your cups, Julia), then set out when conditions are right (warm air temps, warm ground temps).
There are 3 plants I MUST grow every year or my customers yell at me...Moonvine, Tithonia, and Sungold tomato plants. I've had a dedicated following for more years than I can remember who come each year and buy at least one moonvine, one tithonia, oftentimes buying more than one of each. Once you're hooked there ain't no turning back!
