Changing Coleus Colors with Sunlight Levels (growing in bright light vs indirect light)

One of the fun things about coleus plants is that they can change how much color they have based on how much they are exposed to light (the ratios of colors change in new growth, it won't change what colors are there).  I kept two clippings from my coleus propagation success and left one in a southern window (lots of sunlight) and one in a bright room but away from direct light. The results are pretty easy to see: more light meant more of the dark red coloring, and less light meant less red and more white/green.  In general, coleus will produce darker colors if exposed to more light, and more lighter colors if they get less light.

On the left: Coleus grown in bright sunlight (southern window).  On the right: Coleus grown with only indirect light.


  1. Congrats on passing kindergarten :)

  2. It's been a long struggle...

  3. Neat! My aunt gave me several clippings (very small!) today and I put about half in soil and half in clear bottles...so I will see! Maybe I will put one in my kitchen window when they grow to check the different lighting out. Thanks for the info.
