About this species:

        Interesting benefits to wildlife features:

Foxglove beardtongue is deer resistant and poisonous to animals. It is an excellent landing pad for bees, butterflies, and hummingbirds. It attracts pollinators and birds.

This plant can be poisonous to cats and dogs. And even humans can be affected by it. No part should ever be ingested. It is suggested that gloves or long sleeves be used when planting or weeding.
