Thorn Bush Seeds are items used to grow thorn bushes, plants which deal damage to players touching or attacking them (useful for base defence). Additionally, placing them will not fail the Be Peaceful quest, so if you must have defenses that deal damage while completing this quest, Thorn Bushes may be used. They were added in the Merry Christmas update. Thorn bush seeds used to spawn naturally in the forest, and could be obtained by hitting them. Now you need to craft it with 8 thorn bush, or buying them for 30 Tomatoes. To grow Thorn Bushes, a player can plant the seeds anywhere in the Forest, or in any biome with a plant plot (and a bridge if in the Ocean). 16 Thorn Bushes may be traded for 1 reidite, and 40 Thorn Bushes may be traded for 1 garlic seed.


When planted, thorn bush seeds look similar to berry seeds, but green. Thorn bush seeds grow into a thorn bush 4 minutes after planting, and will regrow a thorn bush every 15 seconds if the thorn bush has been harvested. They will be reverted to a planted seed when the thorn bush is harvested.

Thorn Bush Seeds will grow into harvestable thorn bush 20% faster when grown in a plant plot, with an additional boost of 20% when using a peasant's tunic or 40% faster when using a winter peasant's tunic (effects from the tunic and plant plot stack).

Thorn Bush Seeds have a limited amount of health (1000), and last longer when harvested by hand, instead of tools or weapons. If not damaged in any way, thorn bush plants naturally de-spawn after 8 days.

Every 3 minutes, Thorn Bush plants dry up. When a Thorn Bush plant is dried up, it will no longer be able to grow after being harvested. Dried Thorn Bush plants can be replenished by watering them with a full watering can.
