Coleus plants are grown almost exclusively for the colorful foliage with their leaves ranges from green, purple, orange, red, yellow and all in striking patterns.
They are hardy plants that thrive in pots under the right conditions...
Try and keep the temperature above 60 degrees temperature
These plants like humidity
Bright indirect light, too much sun will wash out the colors
Keep Soil continuously moist, water a little less during the cold months.
Fertilize in spring
If your Coleus stars dropping leaves it might be too cold and not getting enought light.
Enjoy your Coleus!
