seeds of Atropa belladonna - Deadly Nightshade
Atropa belladonna, commonly known as Belladonna or Deadly Nightshade, is a perennial herbaceous plant in the nightshade family Solanaceae, native to Europe, North Africa, and Western Asia. The foliage and berries are extremely toxic, containing tropane alkaloids. These toxins include scopolamine and hyoscyamine which cause a bizarre delirium and hallucinations and are also used as pharmaceutical anticholinergics.
Growing from seeds:
These seeds need a stratification first, meaning that they have to be treated with cold for several weeks. This can easily be done by planting them directly into your garden at autumn and then they'll start to germinate in spring.
Second option is just simulating the winter season by putting seeds, together with some soil, into the fridge for about 4-6 weeks.
Third option is a treatment with GA3 (Gibberellic acid) for about 6 hours. Then they can be planted directly. Instructions for GA3 usage can be found in the item description of this phytohormone right here in my store.
After stratification just sow about 5mm deep in well drained soil
