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.

RHS says: "Ornamental bulbs, not to be eaten." That is a caution, not a toxicity finding, and ASPCA has no entry, so no pet verdict is given. That is not a statement that the plant is safe. Keep dogs, cats and horses from eating it.
