Crown Vetch (Coronilla varia )
Crown vetch is used primarily for ground cover and erosion control. It spreads rapidly in sunny areas and can be seen most often along roadsides and open fields.
Crown Vetch can survive in a variety of environmental conditions including drought and rocky dry area, but is not tolerant of shade.
It may be planted in gardens as an ornamental, but caution should be taken since it is considered an invasive plant in many parts of North America.
The Crown Vetch has a long creeping stem and pea-like flowers ranging in color from pink, rose or lilac. Its blooming season is May through August with seeds maturing in September.
