Domestic Rabbits: Safe for small pet consumption in moderation, no associated toxicity recorded

Confusion Risk

The following plants look similar and may be confused:

Common Morning Glory Ipomoea tricolor

Both have similar heart-shaped leaves and vining growth habits; common morning glory contains toxic lysergic acid alkaloids, while sweet potato vine is non-toxic

Field Bindweed Convolvulus arvensis

Bindweed shares the same vining growth and funnel-shaped flower structure as sweet potato vine; bindweed is mildly toxic to livestock, unlike sweet potato vine
