This plant can be used in both PvP or as a mob defense. Along with the seedbag it drops, when you right click it to harvest, it drops razor wire blocks. These blocks are transparent and can be moved through, but do damage like a cactus. They do not destroy items.
The appearance of this crop suggests a kind of iron rose, with rusty metal thorns. It does damage when stepped on.
