Flowers: Closed, vase-shaped heads, that show a yellow eye of bunched flowers at the tip. Involucral bracts are distinctively black-tipped. In loose clusters (cymes) at the ends of branches.

Comments: Introduced from Eurasia, this species is a troublesome weed in some areas, often sprouting in recently tilled soil. The plant contains a toxic alkaloid that can cause liver damage if consumed in sufficient quantity.

Where to find it: I have found this plant mostly growing as a weed in the gardens around the lodge.
