Buy RS3 Rosemary
Rosemary is a flower in RuneScape 3. Players grow it in a flower patch from a rosemary seed at level 11 Farming. Each harvest gives 66.5 Farming experience, and there is a small chance to get harmony moss when you pick it.
Rosemary is useful for more than just Farming experience. When it is fully grown in a flower patch, it protects nearby cabbage patches from disease. This makes it a smart pick for farmers who grow cabbages. Rosemary is also needed to craft dense honeycombs, and it can be used to make imp repellent.
Players who use Invention can disassemble rosemary. It gives mostly organic parts, with a small chance of crafted parts, enhancing components, healthy components, or living components.
Growing rosemary yourself takes time. The plant needs 20 minutes to grow, and it can catch disease along the way. Buying rosemary skips the wait and the risk. You get the flower ready to use for crafting, crop protection, or disassembly right away. It is a light item, so it is easy to carry with your other Farming and crafting supplies.
