It looks like the Canadian moonseed. See picture to confirm. If it is, the botanical name is Menispermum canadense L. The Common name is: Canadian moonseed.It is a woody vine, climbing on adjacent plants or running along the ground if nothing is available to climb on. The leaves are simple, alternate and usually shallowly lobed. Fruits are blue drupes 6-10 mm diameter with a single large flattened seed suggesting a crescent moon (and thereby providing the common name). The fruits are reported to be poisonous with potentially fatal consequences. The fruits are roughly similar to those of our Vitis riparia (frost grape) and wild food foragers should be very careful to distinguish between the two, and to refrain from eating wild fruits if they are not absolutely sure of the identification. Because of this, it is not a highly recommended plant for gardens where kids live near. It is hardy to zone 5. It is in flower from June to July, and the seeds ripen from October to November. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required)The plant is not self-fertile. The plant prefers light (sandy), medium (loamy) and heavy (clay) soils. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil. Ideal for large areas where birds and small mammals can feed and find refuge
