The choices of landscaping plants are endless. For example, you can choose begonias for landscaping plants. Begonias are succulent tropical herbs. Despite their tropical origin, begonias prefer moderate temperatures and partial shade. There are over 10,000 cultivated begonias that are commonly grown as outdoor ornamental plants for landscaping. Begonias display a wide array of variegated foliage, with different color, patterns and sizes of the variegation. Begonias also come in a variety of colors, including pink, yellow, salmon, red and white. They grow dense and compact foliage and usually grow to be between 6 and 9 inches tall (though sometimes they can grow to 12 feet long). Their notable leaves are usually marked, large and asymmetric. Some begonias are much smaller; there are begonias that are merely 1/2 inch in width.
