Growing Arnica and Anise Commercially
Answered by: Inge Poot
Question from: Elaine Webb
Posted on: May 28, 2010

We are just starting up a medicinal herb farm on Vancouver Island, BC, Canada and we need to know what the yield per hectare is for arnica.

Arnica montana seems to yield about 300kg/ha of dry matter (according to research one in New Zealand).

We are so sorry, but none of our references give any yield information on the American arnica. There is an article available on the web for US$30 that compares flower head yields of A. chamissonis with and without fertilization. The article is called "Flavenoids and essential Oil in Flower heads of Introduced Arnica chamissonis" by D.Roki, N. Mekovic etc in the Journal of Herbs, Spices & Medicinal Plants.

We also need to have cultivation info and yield amounts for anise.

Anise needs rich, well-drained, sandy and uniformly moist soil, with a pH of 6.3-8.2. Seed at the rate of 10-17kg/ha. For 90cm rows 5.5 kg/ha is sufficient. Plant 1.25 cm deep. Direct seed only.Seed viability plummets after 2 years. Matures in 4-5 months. Harvest when tips turn grey.Yield is 450-1000 kg of seed per ha.
