What Is Considered "Full Sun?"

Just what is considered "full sun?" Is it measured by hours of sun per day, or does it mean that the plants are in the sun during the hottest part of the day?

When you read "full sun," it means that a plant needs direct, unfiltered sunlight for at least 6 hours a day. This is the minimum amount of light a sun-loving plant needs to thrive. As you've noticed, the intensity of sunlight varies depending on the time of day. A plant that gets direct sun all morning, but is shaded in the afternoon, has a much different growing environment from one shielded from the sun in the morning but exposed to full sun in the afternoon.

Some plants will thrive on 6 hours of direct morning sun, but can't handle the intense heat of direct afternoon sun.Many plants that are classified as growing best in "partial shade" or "partial sun" can take full morning sun, as long as they're protected from direct afternoon sun. Latitude and elevation play a role too. Gardens in the South receive more intense sun than those in the North. And gardens at high elevations are brighter than landscapes at sea level.
