Potato cactus seed

A potato cactus seed is a Farming seed from which potato cacti may be grown, requiring level 86 Farming. It is planted in the cactus patch in Al Kharid. It can be protected by paying a farmer 10 watermelons, although this is unnecessary if the player has completed the hard Desert Tasks.

In addition, if the hard desert tasks have been completed, the plant will grant 6 potato cacti instead of 3; however, a giant ent familiar may also enhance that amount. It does not need to be replanted after harvest, and will yield more potato cacti over time, similar to a regular Cactus.

The seed may be obtained by hunting most jadinkos, high level pickpocketing such as Dwarf Traders and Elves or from the Grand Exchange.
