Many vegetables, herbs, and flowers fall into this category. They include tomatoes, peppers, basil, and sunflowers. To meet their needs, ensure your garden receives at least 6 hours of direct sunlight, ideally between 10 am and 2 pm when sunlight is strongest.

However, even full sun plants can benefit from some afternoon shade in hot climates to prevent sunburn and heat stress.

Partial Shade Plants

Many fruits, shrubs, and shade-loving flowers prefer partial shade. These include blueberries, azaleas, and hydrangeas. They provide color and interest to gardens that receive less sunlight.

Partial shade gardens can be found under the canopy of trees or near buildings that cast shadows. They typically receive 3 to 6 hours of sunlight, often in the morning or late afternoon.
