Common Name: Flower-of-an-Hour (Flower of an Hour)
Latin Name:Hibiscus trionum
Family Name: Malvaceae
Although many varieties of Hibiscus are safe tortoise food, the Flower-of-an-Hour (Hibiscus trionum) is known to be toxic to goats, and there are reports of it being toxic to other animals as well. So in the absence of any specific evidence of its suitability as food for tortoises, we prefer to err on the side of caution and advise that you do not feed this plant.
This rather small annual has flowers that are mainly white (although some are yellow) with a dark purple centre.
