Evergreen and therefore symbolic of eternal life, ivy is a common sight in cemeteries and is often seen growing over old ruined castles and churches. It’s also a popular plant with pagans and wiccans. To top it all, certain varieties of ivy are poisonous, making it a plant with lots of goth appeal.
Perhaps the most ubiquitous plant of all in Goth imagery is the rose. The red rose is a universal symbol of romance, and for Goths it is often associated with vampires due to its colour and sharp, fang-like thorns. The black rose was formerly a symbol of anarchism but these days has been appropriated by goths as an even gothier rose variant. And it *just about* exists in nature as the very dark red Baccara rose.
