If they have sun until 3 pm that's fine. No morning sun but full afternoon sun is fine as well. Aim for at least 6 hours of direct, full-on sunlight. In addition to giving you more blooms in full sun, sunlight helps ward off foliar disease and increase plant vigor. By definition, full sun is over 6 hours daily. More is better.
