Flowers are dark blue or white with a lower lip longer than the upper lip.
What is it used for?

Where does it grow? How we grow it?
Coleus enjoys a moist, fertile, well-drained soil. Most types of coleus are very light sensitive and will easily sunburn. Coleus are also sensitive to the cold; do not plant until all danger of frosting has past. When it is warm enough to plant, remember that Coleus needs room to grow and place them 12" apart. Remove the flower "spikes" as they form.
What are its primary problems?
Coleus is prone to mealybugs, and slugs.
How do we propagate it?
Sow the seeds indoors 10 weeks before the last frost. Coleus will germinate in 10 days. Remember to pinch regularly to promote branching. Coleus cuttings can be overwintered as house plants.
