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.

ASPCA has no page for this plant, so the app makes no pet-safety claim either way. NC State tags this plant non-toxic for cats, dogs and horses but gives no poison section.

PlotAndPetal cannot tell you whether a plant you found can be eaten. Only someone who can see the plant can identify it.

Look-alike warning

Could be mistaken for Plants that share its name. To tell them apart: Looks like native Florida sword ferns (Nephrolepis exaltata, Nephrolepis biserrata); NC State says this one has tubers and the natives do not..

Poison control

If someone has collapsed, cannot be woken, is having a seizure or has trouble breathing, call 911 now. For any other possible poisoning, call Poison Help: 1-800-222-1222.

Emergency number source: U.S. federal law (47 U.S.C. § 251(e)(3)), read 2026-10-07.
