The artificial nectar does the job just fine. It's just too much mess and trouble. Besides, I'd rather feed Hummingbirds the natural way - the way nature has been doing it for thousands of years. With flowers.
For the record; my nectar masses (each at least 20 square feet) are Turks cap, Lantana and Mistflower. (Each mass is composed only of one species, except one has a tree in the middle). There are also Flame Acanthus, Spiderwort, Butterfly weed and Roughleaf Dogwood randomly growing in the yard. Being native, they all do fine in Texas' radical climate.
