They're not undead and they're not triffids, but the plants in the Gothic Garden are all creepy. Dracaena exudes a blood red sap, the black coleus fears sunlight and the moonflower is associated with witches' brews. Aloe is used for embalming and the mimosa pudica shrinks and moves when touched or chilled. Throw in a few tombstone stakes, stickers, skulls, plastic spiders and blood red rock, and you've got a veritable terrarium of terror!
