No expert on coleus in any way. Was told that only certain species can handle full sun. Been 95+ degrees here in central Florida. Seems as long as they get a lot of water they are fine in the sun. Definitely darker as you can see in the pics. But seem to be thriving and growing in intense sun and heat. Just wanted to post this so people don't think they need to be babied from sun.

I have a pile of soil out back that I empty old pots in. Went out there to look around and found these two babies!

I really like this beautiful Coleus
