Common Name: Butterbur (Common Butterbur, Bog Rhubarb)
Latin Name:Petasites hybridus, syn. P. vulgaris, P. officinalis, P. ovatus
Family Name: Asteraceae/Compositae
Butterbur contains pyrrolizidine alkaloids in all parts of the plant, and although it is more concentrated in the rhizomes and stem, the leaves and flowers contain it too. These alkaloids can cause serious damage to the liver, so avoid feeding this to tortoises.
Although flowers are mainly purplish-pink, the White Butterbur (Petasites albus) has white flowers. Do not confuse with Winter Heliotrope which looks similar.
