Common questions
Is string of hearts related to string of pearls?
Not closely — pearls are a Senecio/Curio with real toxicity, hearts are a Ceropegia that is safe. Do not judge one by the other.
Can the tubers hurt my dog?
No. The underground tubers and aerial bead-like tubers are part of the same non-toxic plant.
