field bindweed

Convolvulus arvensis

Description:

Field bindweed is native to Europe and Asia. It is a climbing or creeping herbaceous perennial plant growing to 0.5–2 m high. The leaves are spirally arranged, linear to arrowhead-shaped, 2–5 cm long and alternate, with a 1–3 cm petiole. The flowers are trumpet-shaped, 1-2.5 cm diameter, white or pale pink, with five slightly darker pink radial stripes. Flowering occurs in the mid-summer, when white to pale pink, funnel-shaped flowers develop. Flowers are approximately1.9-2.5 cm across and are subtended by small bracts. Fruit are light brown, rounded and 0.3 cm wide. Each fruit contains two seeds that are eaten by birds and can remain viable in the soil for decades. Although it produces attractive flowers, it is often unwelcome in gardens as a nuisance weed due to its rapid growth and choking of cultivated plants. It was most likely introduced into North America as a contaminant in crop seed as early as 1739, as an invasive species. Plants typically inhabit roadsides, grasslands and also along streams. Its dense mats invade agricultural fields and reduce crop yields.

Habitat:

On regularly mowed school field near urban nature trail.
