This species is perennial. Iwasaki has noticed this, and he says in 

 his Honzodzufu 1. c. that it comes out from the perennial root. It is 

 true and it is always perennial in Japan and Corea. Nasturtium 

 indicum is an annual plant as Roxburgh (Flora indica III. p. 123-4 sub 

 Sinapis divaricata 1832) and J. D. Hooker (Flora of British India 

 I. p. 134; 1875) say. Nasturtium montanum is annual, too, and 

 Roxburgh notes ' Root of about three month's duration.'
