Potato cactus

Potato cactus is a members-only item that currently has the following uses with two member skills:
 * Herblore – as a secondary ingredient when creating magic potions.
 * Summoning – as a binding component when infusing spirit kalphite pouches.

Kalphite Hive


There are a total of 10 spawns in the Kalphite Hive:
 * 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: Prior to a player entering the Kalphite Hive, it is highly recommended they bring along a few antipoison potions, as Kalphite Soldiers and Kalphite Guardians are poisonous. Kalphite workers and the Kalphite Queen, however, are not poisonous.

Soul Wars
Additionally, they can be randomly obtained as a reward by gambling two zeal points in the Soul Wars activity.

Monster drops
Potato cacti can now be obtained as drops from Desert Strykewyrms.

Puro-Puro
Potato cacti are a possible drop from a Spirit impling.

Trivia

 * The Potato cactus' appearances resemble those of the brittle pricklypears (Opuntia fragilis) found in dry western regions of North America.
