Buy RS3 Bloodweed seed
The Bloodweed seed is a Farming seed in RuneScape 3. It grows into grimy bloodweed. This seed can only be planted in one spot, the Wilderness herb patch. That patch sits near the Wilderness canoe stop, north of the Wilderness Crater.
You need level 57 Farming to plant it. Planting gives 72 Farming experience. Each herb you pick gives 81.4 more experience. The crop takes 1 hour and 20 minutes to grow. It has at least 3 harvest lives, and better compost adds more. Supercompost, ultracompost, or the Fertile Soil spell will boost your yield.
No gardener watches this patch, so the plant can get sick. If you finish the Wilderness hard achievements, the patch will never become diseased. Good compost also lowers the chance of disease if you have not done those tasks yet.
These seeds come from the Bandit Duty Free shop in the Bandit Camp, sacks of wild rewards, and the Wilderness shared loot table. That loot comes from the muddy chest, pickpocketing Rogue Enforcers and Rogue Captains, and killing revenants or Wilderness Slayer targets. Grab a Bloodweed seed and grow this herb for solid Farming experience.
