Astragalus is a bushy member of the pea family with pendulous yellow flowers. The sweet roots are one of the main tonics used in Chinese Herbal Medicine. Known as Huang Qi, it is a renowned protector from infection and a reliable source of energy.
 
We have had good results growing astragalus in the UK climate, both in full sunshine and semi-shade. It is a perennial that grows to around 80cm tall; it is quite a delicate plant that is normally harvested after 3-5 years, so choose a sheltered spot that is protected from threats of strong winds, domestic animals or wild children. The rewards are well worth the wait.
