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.

The safety check found no ASPCA page for red clover; the ASPCA page for alsike clover (a different species) lists horses only. USDA NRCS notes red clover can cause bloat in grazing livestock. Not listed means no pet-safety verdict was found, not that the plant is safe. Keep pets from eating it and call a vet or the ASPCA Poison Control line if a pet seems unwell.

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

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.
