Well, golly, I'll just have to give Mr Lincoln another try. It doesn't get so hot here, the mid nineties in August. The trick is long warm nights. Dark at seven in the summer, not light until light at six in the morning. And no cooling off, the nights are usually only ten degrees cooler than the nights.
Many things will expire here because they don't get a rest at night. Spinach keels over days from emergence. Tomatoes refuse to set fruit except for a few months, between December and April. A friend tried to grow a catalpa from seed, it withered away.
Seems that you could grow anything, but plants are too sensitive to both day length and temperature variation.
Porkpal, what is the difference in temps in your summer?
And now I will also try First Kiss. What a name! Is it an awkward plant?
