Known Hazards: None known Mature Height: 2 Mature Width: Habitat: Found only on Amagi mountain in the wild[174].
Cultivation Notes: Tolerates most soil[200], thriving in a well-drained loamy soil[1], but resenting dryness at the roots[11, 200]. Succeeds in full sun or semi-shade[200], but if it is grown in a low rainfall area then it requires shade at the hottest part of the day[11]. Does well on very acid soils with a pH around 4.5[200]. The colour of the flowers reflects the pH of the soil the plant is growing in, the flowers are pink in a neutral to alkaline soil and blue in an acid soil.Best grown in an acid soil, doing well on very acid soils (pH 4.5).
There is some confusion over the correct name for this plant. We have used the name in [174] but the Flora of Japan[58] says that the correct name is H. macrophylla angustata.
Plants are hardy to about -25°c when dormant but the young growth in spring can be killed by late frosts.
This species is notably susceptible to honey fungus[200].
