Sun/part shade. Snailseed is a deciduous vine with a tenacious habit. Ornamental qualities include abundant red berries in autumn; the coiled seeds resemble snails.
Snailseed is probably already present in any shaded area. It can be a difficult weed to control in the garden, entangling small plants. But consider leaving a patch on the chainlink if you need a tough native vine: the fruit is an excellent resource for alley wildlife, mockingbirds and cardinals.
