Polly Spout green dragon (Pinellia tripartita'Polly Spout') is a hardy member of the Aroid (philodendron) family, which produces spikes of green flowers in late summer. This cultivar is named for the hometown of We-Du Nursery in South Carolina, where this sterile cultivar was created. Plant Polly Spout in shade or woodland gardens for the textural effects of the deeply divided green leaves that resemble jack-in-the-pulpit. One of the few hardy aroids that hold their foliage all summer long, rabbits and deer avoid this species because of toxic chemicals in the sap. These chemicals can also cause dermatitis in sensitive individuals.
