Cultivation Details

Adenophora triphylla has a wide range from the cold, temperate zone of the Russian Federation south to the tropics of Vietnam and Laos. It is usually found at low elevations in the north of its range, but is more likely to be found at higher elevations towards the south - it is found up to 2,000 metres in southern China[]. Plants, at least those obtained from the north of its range, are hardy to about -20°c, perhaps even lower if the soil is reliably well-drained[, ].
Prefers a light rich slightly alkaline soil that is not too dry and a warm sunny position[, ]. Prefers a moist peaty soil in sun or partial shade[].
This species is extremely polymorphic, and several varieties and forms have been described in Japan. The many variations in several characters (hairiness, leaf-shape, inflorescence-shape etc.) can be seen in individuals growing intermixed[].
This species succeeds in a meadow if the grass is not cut until after the plant flowers[].
Intolerant of root disturbance[].
The young growth is extremely attractive to slugs, they have been known to destroy even mature plants[].

Edible Uses

Root - cooked[, , , ]. A sweet flavour[]. The root is thick and carrot shaped[]. The root can be 70 - 160mm long and 15 - 18mm wide[].

Propagation

Seed - best sown in a cold frame as soon as it is ripe[]. The seed can also be sown in spring. Surface sow 2 - 3 seeds per pot in the spring in order to avoid transplanting[]. We have found that if transplanted when very small seedlings grow away without difficulty[]. Germinates in 1 - 3 months at 10°c[]. Plant out into their permanent positions whilst young.
Basal cuttings in spring[].
