Safety & Hazards
Although no specific mention has been seen for this species, many members of this genus contain furanocoumarins. These have carcinogenic, mutagenic and phototoxic properties[1]. Skin contact with the sap of some members of this genus is said to cause photo-sensitivity and/or dermatitis in some people[2].
Cultivation Details
We have almost no information on this species and do not know if it will be hardy in this country, though judging by its native range it should succeed outdoors in much of Britain. The following notes are based on the general needs of the genus. Succeeds in any ordinary garden soil, doing best in moist soils or deep woodland[3].
