Rhododendron ponticum
Ten ways of seeing
- measured cast yellow-green
- upright 1.73 : 1
First Look
江馆清秋，晨起看竹，烟光日影露气，皆浮动于疏枝密叶之间。
—— 清·郑板桥《题画竹》
On an autumn morning at the river lodge I looked at the bamboo: mist, sunlight, dew, all drifting among the sparse and dense leaves.
The sheet is vertical: the eye climbs and settles in the upper half. Let the plant stand before you look for detail. Then step in close: watch where colour meets line, and whether the line ever breaks. Third, find where the yellow is deepest: the whole tonal order is measured from that patch.
Name and Thing
The binomial is Rhododendron ponticum: the first word is the genus it belongs among, the second the epithet that sets it apart. Two words carry a whole provenance. The Chinese name 彭土杜鹃 is a modern rendering of the Latin, not an old garden name.
Form and Colour
Measured on this plate: flower colour covers 30.8% of the sheet, foliage 0.0%, the cast yellow-green with a second note of amber. No other plate shares exactly this measure. Garden annuals and low perennials: many small, brilliantly coloured flowers to a stem, with leaves palmately lobed, pinnate or entire — the mainstay of the Victorian bedding scheme. Filed under yellow — a honey-yellow, built in washes from a pale ground. Three things fix the habit: leaf arrangement, tepal count, and how the flower is borne.
Composition
The sheet is tall. No details are appended: a plate for looking, not for keying out. The plant fills 80% of the sheet, centred near the centre — the herbarium way, drawn to be read whole.
Line and Colour
Eighteenth-century plates are mostly copper engraving: hatched lines for shadow, then hand-colouring by another hand. Take a loupe to three places: petal edge, leaf vein, caption. An unbroken line means engraving; colour crossing the outline means a hand. If you mean to copy it: take its skeleton, its margins and the order of its colours; the burin's hatching is the language of copper — suggest it with pencil density, do not imitate it stroke for stroke.
Poetic Resonance
词藻世传平子赋，园林人比郑公乡。
—— 唐·皇甫冉《館陶李丞舊居》
The poem gives the mood first and the picture supplies the form; set the line beside the plate and the yellow the corolla becomes its resting point.
Symbolism
Bedding plants carry no imperial weight; they mean the everyday — window sill, border, festival, gift. Victorian floriography grew up among exactly these flowers. This plate leans yellow, which in flower language adds one more degree of feeling. Meanings change their tune: the same flower can say opposite things within a century.
Season and Place
under glass they could be had from March. Gathered from everywhere by plant hunters and the glasshouse trade: pelargoniums from South Africa, campanulas from European mountains, lobelias from North America, fuchsias from Chile. The year 1781 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. See this kind of plate in the flowering season if you can: once you have met the living flower, you stop reading only colour.
The Book and the Hand
“Icones Plantarum Rariorum” carries only Nikolaus Joseph Freiherr von Jacquin's name. A plate is collective work: drawer, engraver and colourist were different hands, and the unnamed ones decided how good it looks.
What to Take Away
Carry three rules away: whole before detail; line before colour; picture before book. A flora exists to be consulted; look long enough and you forget to consult — someone in 1781 gave a whole day to a single flower.
