Belladonna seed

A Belladonna seed is used in Farming, and grows into cave nightshade. Players can only plant it in the belladonna patch, which is located at Draynor Manor. They require level 63 Farming to plant the seed, and players gain 91 experience for planting it and 512 experience for successfully harvesting it.

There is no nearby gardener that will watch over your growing belladonna plant.

Farmers must pick nightshade with gloves equipped, or they will be hit for 20 poison damage instead of harvesting the nightshade. Certain decorative gloves, such as Mime gloves, do not work safely. Some other items that go in the hand slot also work, like the Regen Bracelet.

Trivia

 * Probably named from the real world plant Atropa belladonna, which is sometimes called "belladonna" or "nightshade," or even "deadly nightshade." In older times it was used in making not only poisons, but medicines, recreational drugs, and cosmetics.
 * "Bella donna" means "beautiful woman" in Italian, because the drops were mainly used to dilate a woman's pupils, making her more attractive by the times' standard.
