Batface can take a little shade, but all the others do better with as much sun as possible. The only one I've ever had a problem with is the Giant Cigar Cuphea. I planted 2 in March, and they bloomed until May, but haven't done anything but grow since then, like 4 to 5 feet tall. I just cut one down since it was overtaking other plants that were blooming. If you haven't tried ignea yet, try to get some since it's perfect for hummers.

You might try Cuphea Ignea next year. That is I'm pretty sure its ignea since it was mislabeled by Lowe's as Mexican Heather. In any case, my plants have been in bloom every second since they were planted in early June and are now close to two feet tall. Additionally, not a single leaf has been eaten. My hummingbs have not been using them on a regular basis, but I think that is because of the several dozen other hummer plants in the same bed. Basically I've left these cupheas to their own devices. They get watered maybe once a week if it doesn't rain. They get sun from about 10AM until late afternoon when taller plants they are growing out of give them some shade. Their soil is a sandy loam.

My batface has done very well in a large pot in partial sun - it now needs a lot of water - I also bought the cigar plant, and put it out where I could not see it, and then brought it closer, and there is some activity around it, but again it needs a lot of water - they are really large plants, and our little pots do not do them justice - they need to get out there and grow -
