Epipremnum Aureum or "Devil's Ivy"
This is a silly little climbing vine native to the solomon islands! You will often hear that its toxic to pets, and this is because the sap contains insoluble calcite crystals, which cause a LOT of irritation to skin and if ingested. its not going to kill anyone,but for the love of god keep it away from your cat.

crassula rupestris
these plants grow up to 3 feet in their native habitat! They mainly exist on rocks and cliffs in Africa, and they need a soil PH of 6.0.
