Potato cactus is an item that is used with the Herblore skill as a secondary ingredient when creating magic potions and battlemage potions. Potato cactus can also be selected as one of the 3 of 31 items needed for Fairytale I - Growing Pains as well as 1 of 50 items for Mourning's End Part II. They can be grown in a cactus patch by planting potato cactus seeds, requiring level 64 Farming. Eight are also used to pay Taylor to look after a player's Celastrus tree. Collecting 5 of them while inside the Kalphite Lair is a requirement for the Easy Desert Diary.
Farming
At level 64 Farming, a player can plant a potato cactus seed in a cactus patch. They take roughly 70 minutes to fully grow and can be protected by paying a farmer 8 snape grass. Once grown, they can be harvested in a similar manner as normal cacti. Each pick grants 68 experience. Fully grown potato cacti have six "lives". Each pick of a potato cactus has a chance to remove one of the patch's lives. Once all the lives are used up, the player will have to wait for more potato cacti to grow on the plant, which should occur within 25 minutes.
Potato cacti can be used on a compost bin to create normal compost.

Obtaining
There are a total of 10 floor spawns in the Kalphite Lair:
- 1st level – 3 spawn in the south-west room where the Kalphite Soldiers are found.
- 2nd level – 7 spawn on the west wall next to the Kalphite Queen.
Note: The Kalphite Soldiers and Kalphite Guardians found in the lair are poisonous. Players are advised to bring some form of antipoison.

Trivia
- According to the Kalphite Princess, the kalphites collect the potato cacti in order to lure unsuspecting humans and kill them.
- Potato cacti were previously available for purchase from the Nightmare Zone shop for 1,250 reward points. They were removed when the ability to farm potato cacti was added with the Kebos Lowlands update.
