What is Convolvulus?

Convolvulus is a genus of flowering plants composed of about 250 species. Species Convolvulus can be upright, crawl or climbing plants and either annuals or perennials. The name of the genus, which means "wound together", reflects the habit of some species to bind to other plants or landscape features. Among the members of the family with lonely flowers are ornamental morning glory, c. Tricolor and the invasive field Bindweed, c. Arvensis . c. cneorum , sometimes called Silverbush, is a permanent shrub evergreen, which is cultivated for its clusters of flowers. The flowers of the most end species are usually about a wide thumb (2.5 cm) and come in different colors, including white, pink and purple. Most types of Convolvulus prefer poor than average, well -drained soils, as well as full sun and mild watering. Due to their less demanding soil requirements, they are often grown in rock gardens. Most cultivated species also grow well in containers orhanging baskets, which may be desirable if the type tends to spread.

Perhaps the most sophisticated type Convolvulus is c. tricolor . This plant is often called morning glory, but this name is also shared with other types of Convolvulus as well as some other genera. c. tricolor is usually grown as a bushy annual season, which grows about 12 inches (30 cm) tall and produces 1 1/2 inches (4 cm) flowers. Its three -color flowers have a yellow center, a white middle ring and a purple or purple outer ring. Flowers last only a day, but new flowers appear in large numbers throughout the summer.

Tricolor , which are mostly white with yellow center. Flowers roleOne hundred in clusters about five. When growing in a container c. Other cultivated species include c. Althaeoides , c. Sabatius and c.

Some species Convolvulus produce running or spreading roots and can quickly become invasive. The Bindweed field, c. Arvensis is one of the examples, and although it is usually found in the gardens, it can damage agricultural crops. Running roots of Bindweed, which spread underground, can be up to 20 feet (6.1 m) long. Flowers have similar shapes to c. Tricolor , but are usually white with a pinkish shade.
