<human>:  What types of plants need the most sun?
<bot>: Mediterranean plants such as rosemary, lavender, and thyme need a lot of sun and typically prefer temperatures above 50 degrees Fahrenheit during the day. 2 Cacti, succulents, and other desert plants generally require the most direct and intense sunlight and can survive in very hot, dry conditions. 3 Tropical plants such as orchids and bromeliads may require higher humidity levels, but should still receive plenty of direct sunlight throughout the day in order to thrive.
