Cacti

Black Star Aloe "The leaves are a dark black and trimmed with dark purple spikes. The liquid inside soothes burns, and if consumed or worked into a poultice it can defend against Unanswered Questions." If you dry the liquid from inside it will form into a glass-like resin that can be broken and powdered for Incense.

Spirit Cactus "Uncertain of benefits... Mostly dark purple color, but the appendages have a gradient up to a very bright green/white" I've also seen many skilled botonists utilize a spirit cactus to grow other trees as though from a graft.

Flowering Bombadier Cactus "Explodes if not careful. Flower can be used for medicine and tea!" A dark green and stout cactus shaped like a stretched out melon. It’s covered in spikes and ridges and it has a pink flower growing at the top when it is ready to be harvested...unfortunately, this flower also denotes when it is ready to explode if handled too roughly. The flower, if harvested carefully, can be used for medicine and tea. By boiling the flower with your favorite tea, or creating an infusion with just the flower and some water, you can create a great and soothing drink.

Night Vines "Tough, thick, pointy...is actually a cactus that looks like vines. None of the animals go near it. Prefer the dark, a deep blue color, the flowers are dark red." Night vines are actually a type of cactus that grows similar to vines along the ground, twisting around itself and creating a patch of difficult terrain. The “soft and vinelike” appendages are very stiff, hard and covered in spikes.
