Generally speaking, hollyhocks are sun-loving plants that require about 6 hours of sunlight each day to bloom. However, the type of sun an individual plant should receive depends on the climate in which it is planted. Hollyhocks will get scorched and wilt in extreme heat, so if you live in a location with summer temperatures that consistently exceed 85℉, it’s best to plant your hollyhocks in a location where they will receive shade during the hottest part of the day.
