![]() There are hybrids created by crossing tuberous begonias and wax begonias. Afterward, they can be planted in March in containers, so plants are established before transferring outside in May. These begonias have tuberous roots that require a short dormant period indoors in fall and winter. There are trailing and upright forms of tuberous begonias, both of which are commonly planted in containers. Tuberous begonias ( Begonia x tuberhydria) have larger, showy flowers in more diverse colors. While most begonias are not noted for their drought tolerance, wax begonias can be, once established. Wax begonias are noted for their durability in the landscape – tolerating both part shade and full sun. ![]() Single and double flower forms are available. Leaves are smaller than most other types of begonias, and they are usually green or bronze/burgundy. ![]() Semperflorens or wax begonias ( Begonia x semperflorens-cultorum) are the popular annual begonias grown in the home landscape. While wax begonias and tuberous begonias are common landscape plants in Iowa, the rest are more commonly grown as houseplants. All are tropical plants that prefer warm, humid conditions. According to the American Begonia Society, there are seven different types of begonias – divided primarily based on their species and growth habit. There are about 1500 different begonia species native to tropical regions worldwide, including Central and South America, Asia, and Africa. Avalanche begonias in pink or white are rangier, suited for containers and hanging baskets, where their arching growth habit is handsome.Begonias are popular as annual bedding plants outdoors and as houseplants indoors. Good green-leaved varieties are found in the Lotto and Pizzazz series. Related varieties: Popular, dark-leaved kinds are the Cocktail series: Brandy, Vodka, Whiskey, and Gin. They're also suitable in front of summer annual borders and combine well with other cool-colored flowers in mixed plantings and containers. Uses: Wax-leaved begonias lend themselves to large, formal plantings because of their uniform size and shapeliness. Cuttings root readily, so an easier way to start plants is on a sunny windowsill during fall and winter. Germination temperature is 70 degrees to 85 degrees Fahrenheit and requires 14 to 21 days. Dustlike seeds (two million per ounce) must be sown in December or January for large, husky plants by May. Propagation: Most hybrids are grown from seed, but great patience is required. Most hybrids will grow six to nine inches high and spread as wide. They'll form tight, compact plants in full sun, with increasingly looser form and fewer flowers as you move them deeper into the shade. How to grow: Fibrous begonias perform well in rich, well-drained soil, but the soil must be allowed to dry between waterings. There are also varieties with double flowers that resemble fat little rosebuds and others with variegated foliage. The deeper-colored or bronze-leaved varieties offer especially eye-catching contrast with flowers. All four flower colors are available with your choice of leaf color: chocolaty-red or shades of green. They are widely available in market packs.ĭescription: Uniformity is the trademark of most wax begonias: tight mounds of closely packed leaves covered with blossoms. Virtually untouched by bugs or blight, their only shortcoming is a relatively narrow color range. From first setting them out until they are laid low by frost, they'll be packed with white, pink, rose, or red blossoms. These brightly colored bedding begonias are equally at home in full sun (except where temperatures stay above 90 degrees Fahrenheit for days on end) or full but bright shade (where trees are pruned high). Wax begonias, or fibrous begonias, are annual plants. Wax begonias, also called fibrous begonias, are tall.
