Deathweed Seeds are a type of seed that can be obtained from harvesting Deathweeds while they are blooming or using the Staff of Regrowth on naturally grown Deathweeds while they are fully grown. A Deathweed plant only blooms during a Blood Moon, and also during Full Moons in the Desktop version, Console version, Mobile version, Switch version, and tModLoader version. Its blooming state can be identified by the sickly red pods on its leaves. Each plant will drop 1–3 Deathweed Seeds when harvested while blooming.
Deathweed Seeds can be placed on Corrupt and Crimson grass, Ebonstone and Crimstone Blocks, empty Clay Pots, or any types of Planter Boxes, and will grow into harvestable Deathweeds. They will grow anywhere, not just in the evil biomes, but will only yield seeds when blooming.
