Reference excerpt

Hemerocallis middendorffii, known as Amur daylily, is a plant species in the subfamily Hemerocallidoideae of the family Asphodelaceae of the order Asparagales. It is native to the Russian Far East, northwest China, Korea, and Japan. It grows in meadows, mountain slopes, open woods, and scrub. It is cultivated in Asia for its edible flowers.

Description Herbaceous perennial with linear arching leaves to 60 cm (24 in). Flower scapes 20–90 cm (8–35 in). Flowers 5–6, golden yellow to clear orange, large in a terminal head. Flowers in July for 2–3 weeks and often reblooms in September. Four varieties are recognized:

H. middendorffii var. middendorfii: To 90 cm (35 in). Flowers orange, odorless with elliptic to spathulate tepals. Bracts ovate, 2–2.5 cm (3⁄4–1 in). The range of the species. H. middendorffii var. esculenta (Koidz.) Ohwi: Japan H. middendorffii var. exaltata (Stout) M.Hotta: Japan H. middendorffii var. longibracteata Xiong: 20–35 cm (8–14 in). Flowers yellow, fragrant with lanceolate tepals. Bracts ovate-lanceolate, 3–6 cm (1+1⁄4–2+1⁄4 in). Endemic to China.

Cultivation Easily cultivated on moist soil in a sunny site, but can tolerate poor soil and partial shade. Propagated by division and by seed. Takes 2–3 years to flower from seed. Plants prefer a neutral to slightly acid soil and will suffer in very acid or alkaline soils. Generally free from pests and diseases. Hardy to USDA zone 4.

Worked examples

Example 1 — a first encounter with Hemerocallis middendorffii

Start with the simplest possible case. Write down what Hemerocallis middendorffii claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hemerocallis middendorffii before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hemerocallis middendorffii ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hemerocallis middendorffii

In research: Hemerocallis middendorffii appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hemerocallis middendorffii in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hemerocallis middendorffii is common in secondary-school and first-year university syllabi. It links to neighbouring topics Edible plants, Flora of Eastern Asia, Flora of Manchuria, so understanding it makes those chapters shorter.
In everyday life: Look for Hemerocallis middendorffii outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
