We have not researched the safety of this plant yet.

Toxic to pets

No ASPCA entry found.

ASPCA's 'Hibiscus' and 'Rose of China' pages both cover Hibiscus syriacus (Rose of Sharon), a different, cold-hardy species: not Hibiscus rosa-sinensis (tropical/Chinese hibiscus), which this entry is for. The 'Rose of China' name is the most dangerous part of this naming trap, since it sounds like it should mean the tropical Chinese hibiscus and does not. Because this is a naming-trap situation, this entry has no verdict rather than borrowing Rose of Sharon's non-toxic verdict. Do not assume toxicity either way for H. rosa-sinensis from any of ASPCA's three hibiscus-named pages.

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 ASPCA's only 'Hibiscus' entry (Hibiscus syriacus, Rose of Sharon), a cold-hardy deciduous shrub: not this tender tropical species (Hibiscus rosa-sinensis). To tell them apart: Rose of Sharon is cold-hardy and deciduous; tropical hibiscus is tender and typically evergreen in warm climates. No further visual comparison sourced: check the botanical name.. Do not wire Rose of Sharon's non-toxic verdict to this plant; left without a verdict instead. This is a case where the wrong-species page happens to say non-toxic, which could tempt a false 'safe' label: exactly the mistake a species-specific check is meant to catch.

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.
