Are Coleus Plants Annual or Perennial?

Coleus plants are members of the nettle family and should be grown in indirect light or in shade for the best foliage results. While the plant can survive full sun, it does best in shade. Dwarf varieties can be 6 to 12 inches tall, while standard varieties can be up to 3 feet high. Pest problems that are often associated with coleus plants include aphids, slugs, snails, white flies and mealy bugs.
