Convolvulaceae (Morningglory family)
Field bindweed was introduced from Europe and has become a widespread weed problem in all parts of the U.S. except southeastern states. Because of its remarkable adaptability to different environmental conditions, it can be found at altitudes as high as 10,000 feet. It is a difficult weed to eradicate because of the long, deep taproot which can penetrate the soil to a depth of more than 10 feet and which gives rise to numerous long lateral roots.
Growth Habit: Perennial with an extensive root system, often climbing or forming dense tangled mats that can cling or climb.
Leaves: Green, oval shaped, notched opposite the prostrate stem with secondary leaves that become heart or arrow shaped.
Flowers: Numerous white to light pink, bell- or trumpet-shaped, about 1 inch in diameter. The flowering period is from late June until frost in the fall. Fruit is a small, round capsule, usually four-seeded. Seeds can remain viable for as long as 50 years.
Roots: Deep, penetrating with extensive horizontal roots that support the thick flowering mat aboveground. Broken roots will sprout new plants.
Other: Other common names include creeping Jenny, morningglory, perennial morningglory.
