Annual begonia plants have many uses in the summer garden and beyond. Annual begonia care is relatively simple when one properly learns how to grow begonias. Watering is important in the care of begonias, as is the right location.

Known as wax begonias or bedding begonias, annual begonia plants (Begonia semperflorens) grow quickly and easily fill in spaces in the garden that will benefit from attractive foliage and frilly flowers. They can be a focal point when planted in mass and are excellent specimens for container combinations. Annual begonia plants are also deer resistant, so keep them in mind for trouble spots in the landscape.

Plant wax begonias in a full sun to shaded location. Full sun locations during hot summer days may stress annual begonia plants, making them susceptible to disease. Therefore, in areas where summers are exceptionally hot, plant wax begonias where they will get afternoon shade.
