Vigorous trailing legume (Coronilla varia), native to the Mediterranean but widely grown in temperate areas as a ground cover. It has fernlike leaves and clusters of white to pink flowers. The sturdy roots are useful in binding the soil of steep slopes and roadside embankments. As a legume, crown vetch draws nitrogen from the air, trapping it in the roots, and thus improves soil fertility. It dies back to the crown each fall in cold areas, resuming growth in spring. Cutting the plant back in the fall or early spring encourages quick growth.

Many collections of royal jewelry have been assembled, confiscated, and dispersed over the centuries.

Disease of plants caused by the bacterium Agrobacterium tumefaciens. Thousands of plant species are susceptible, including especially rose, grape, pome and stone fruits (e.g., apples, peaches), shade and nut trees, many shrubs and vines, and perennial garden plants. Symptoms include roundish, rough-surfaced galls, several inches or more in diameter. At first cream-coloured or greenish, they later turn brown or black. As the disease progresses, affected plants lose vigour and may eventually die.
