Seeds can be stored successfully in the freezer for certain period of time according to my own experience.

To germinate the seeds: damp paper towel with seeds in a re-sealable bag in fridge for about 1.5-2.5 months and then take the seeds out for sowing in moist but not wet medium in partial shade to light shade location in protected environment.

Seedlings are too tasty for bugs, slugs and snails to grow up. Wait the seedlings to be old enough, at least 6"-8" height then transplant to outdoors in partial shade location. Keep the soil moist.

Plant is biennial but you keep its premature flower stems removed, the plant can live up to 6 years!

The seeds are difficult to come buy and expensive. I had these seedlings twice, planted them out and they disappeared the next day. So make sure that you protect them!

Ashitaba (Angelica keiskei) is without a doubt one of the most exciting discoveries we have made in our plant trials here at the BoTierra Biodiversity Research Center.
This amazing medicinal super-food from the Longevity Islands of Japan has been know for centuries as a healing herb and leafy green vegetable and is rich in vitamins, minerals, enzymes, amino acids, and fiber, containing the rare key factor - chalcones: bio-flavonoids with high levels of anti-oxidant activity exceeding that of red wine and green tea. Ashitaba is one of the few vegetable sources of vitamin B-12 not derived from animal or sea plants.
