Common Name: Dumortier’s daylily
Habitat: Hemerocallis dumortieri is native to E. Asia – Japan (Hokkaid?) , Korea. It grows on meadows in the mountains of N. and C. Japan.
Description:
Hemerocallis dumortieri is a perennial flowering plant , growing to 0.5 m (1ft 8in) by 0.6 m (2ft). Roots slightly fleshy, with oblong, swollen, tuberous part near tip. Leaves linear, narrow, nearly as long as scape, 40–45 × 1.5–2 cm. Scape ascending. Inflorescence short, a 2–4-flowered helicoidal cyme; basal pedicel usually concaulescent; bracts oblong-ovate, apex subacute. Flowers rather small, slightly fragrant, opening in very early morning and closing in very early morning of following day, reddish brown apically in bud. Perianth orange-yellow; tube rather short, ca. 1 cm; segments narrow, 5–7 cm, outer ones 0.7–1 cm wide, inner ones slightly wider than outer, 1–1.5 cm wide. Anthers black. Capsule subovoid. It is in flower from May to June. The species is hermaphrodite (has both male and female organs).
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers dry or moist soil.
Cultivation:
Succeeds in most soils, including dry ones, preferring a rich moist soil. Grows well in heavy clay soils. Succeeding in sun or shade, it produces more flowers in a sunny position though these flowers can be shorter-lived in very sunny positions. Succeeds in short grass if the soil is moist. Prefers a pH between 6 and 7. This species is hardy to about -20°c. Hybridizes freely with other members of this genus. Individual flowers only live for one day. The flowers are sweetly scented. Plants form a tight clump that spreads slowly. The roots are cylindrical. Plants take a year or two to become established after being moved. Plants seem to be immune to the predations of rabbits[233]. The plants are very susceptible to slug and snail damage, the young growth in spring is especially at risk.
Edible Uses:
Leaves and young shoots – are cooked and eaten. They must be consumed when very young or else they become fibrous. Flowers and flower buds – raw or cooked. The flowers are crisp and juicy with a pleasant sweetness and no unpleasant after-taste. They can be dried and used as a thickener in soups etc. The flower buds contain about 43mg vitamin C per 100g, 983 IU vitamin A and 3.1% protein. Root – raw or cooked.
Medicinal Uses: The juice of the roots is an effective antidote in cases of arsenic poisoning. A tea made from the boiled roots is used as a diuretic.
Other Uses:
The tough dried foliage is plaited into cord and used for making footwear. Plants form a slowly spreading clump and are suitable for ground cover when spaced about 45cm apart each way. The dead leaves should be left on the ground in the winter to ensure effective cover.
Known Hazards: Large quantities of the leaves are said to be hallucinogenic. Blanching the leaves removes this hallucinatory component[205]. (This report does not make clear what it means by blanching, it could be excluding light from the growing shoots or immersing in boiling wate
