Humans often harbor prejudices regarding parasites, but parasitic plants have evolved fascinating adaptive strategies for their lifestyles, as well as providing some surprising benefits to wildlife and people. Although only 1% of angiosperms are parasitic, they are very successful. What factors foster the evolution of parasitism? What stimulates germination and how do these plants find their hosts? How do parasitic plants affect community structure? Let’s have a closer look at these plants to see what’s going on under the surface.
