Habitat originel

Alpine regions, in sandy and stony situations in full sun[58, 200]. Rocky slopes and pebbly grasslands of subalpine to alpine regions at elevations of 1500 - 3000 metres[275].

Origine géographique

E. Asia - northern to central Japan.

Comestibilité

• Racine - cuite [105, 177].
• Best if boiled in two lots of water, it then makes excellent eating [179].
• Leaves and young shoots - cooked [105, 177, 179].

Culture

• Prefers a light rich slightly alkaline soil that is not too dry, and a warm sunny position [1, 200].
• Plants are intolerant of root disturbance [1].
• Une espèce polymorphe [58].
• Adenophora nikoensis is sometimes separated into two different species, in which the plant with calyx lobes serrate is named A. nipponica and that with entire ones as A. nikoensis .
• These two forms, however, are often observed in the same place and cannot really be separated [275].
• The young growth is extremely attractive to slugs, they have been known to destroy even mature plants [K].

Propagation

• Graines - Semez sous chassis dès qu'elles sont mûres [200].
• The seed can also be sown in spring .
• Surface sow 2 - 3 seeds per pot in the spring in order to avoid transplanting [133].
• We have found that if transplanted when very small seedlings grow away without difficulty [K].
• Germinates in 1 - 3 months at 10°c [133].
• Plant out into their permanent positions whilst young .
• Boutures de la base au printemps [K].
• Division in spring - very difficult because the plant dislikes root disturbance[1] .
