Latin Name:  Iris tectorum
Common Name:  Roof iris
Family:  Iridaceae
Author:  Maxim.
 
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:  0.3   Mature Width:  0.5
 
Habitat:  Grows wild on shady rocky slopes and in scrub, it is also found planted on thatched roofs in Japan.



Cultivation Notes:  Prefers a well-drained loam rich in leafmold with plenty of moisture in summer and an open sunny position[1, 42, 79, 200]. Requires a really well-drained soil that is dry rather than damp, and a hot sunny position[233]. Prefers a lime-free soil but succeeds in most good soils and in partial shade[79]. Succeeds in dry soils and, once established, is drought tolerant[190]. Cultivated for its edible root in Japan[2]. There are some named varieties, selected for their ornamental value[233]. In China the plants are grown on the roofs of houses[190]. Plants do not flower so freely in cultivation in Britain. In their native habitat they experience cold dry winters and warm wet summers[187]. It is best to lift the plants in October, store them in sand in a cool frost free place over winter and replant in March[1]. Members of this genus are rarely if ever troubled by browsing deer or rabbits[233].
