Latin Name:  Iris japonica
Family:  Iridaceae
Author:  Thunb.

Known Hazards:  Many plants in this genus are thought to be poisonous if ingested, so caution is advised[65]. The roots are especially likely to be toxic[238]. Plants can cause skin irritations and allergies in some people[238].

Mature Height:  0.6   Mature Width:  1

Habitat:  Woodland hills[58], grassy and rocky slopes and among rocks by streams[187].

Cultivation Notes: Prefers a gritty well-drained soil with plenty of moisture in summer and shelter from early morning sun[1, 42]. Prefers a lime-free soil but succeeds in most good soils[79, 200]. Succeeds in full sun or partial shade[79], but plants flower better in a hot sunny position[190]. Established plants are drought tolerant[190]. Cultivated for its edible root in Japan[2]. A number of named varieties have been selected for their ornamental value[187]. It is best to lift the plant in October, store in sand in a cool frost-free place over winter and plant out in March[1]. Plants have creeping aerial rhizomes that root at intervals[187]. The flowers are susceptible to damage by late frosts, the plants failing to flower after an exceptionally cold winter[187]. Members of this genus are rarely if ever troubled by browsing deer or rabbits[233].
