How complete this information is
The safety information on this page is partial. Where a source covers a point, it is shown; where none does, the page says so.
Toxic to pets
No ASPCA entry found.

No ASPCA page or other pet statement was found. That is not a statement that the plant is safe.

Human edibility not yet verified. A pet-toxicity listing answers a different question and does not mean any part of this plant is safe for a person to eat, raw or prepared. Check WHO, FDA, CDC or your extension service before eating any part of this plant.
