Ipomoea batatas and Heliconia psittacorum (1719)
Ten ways of seeing
- measured cast yellow-green
- slightly upright 1.29 : 1
First Look
竖划三寸，当千仞之高；横墨数尺，体百里之迥。
—— 南朝宋·宗炳《画山水序》
A vertical stroke of three inches stands for a cliff of a thousand fathoms; a few feet of ink holds a hundred li.
Slightly taller than wide; the eye lands above centre. 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
Only the genus Ipomoea is given; species-level names came later. No established Chinese name exists, so it is cited by its binomial alone.
Form and Colour
Measured on this plate: flower colour covers 18.3% of the sheet, foliage 7.5%, the cast yellow-green with a second note of red. 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. Read the outline, then the colour layers, then the brush.
Composition
The sheet is slightly tall. No details are appended: a plate for looking, not for keying out. The plant takes about 28% of the sheet, centred near the centre — the easy measure most florists kept to.
Line and Colour
Eighteenth-century plates are mostly copper engraving: hatched lines for shadow, then hand-colouring by another hand. Decide first whether it was printed or painted; only then discuss whether it is beautiful. 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
不嫌野外无供给，乘兴还来看药栏。
—— 唐·杜甫《有客》
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. In a flora it is a species first and a symbol second; the order is worth keeping.
Season and Place
Late spring to early autumn, June through September. 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 1719 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. The bud and the ripe fruit on one branch tell the season; the name in the title often tells the journey.
The Book and the Hand
“Dissertatio de generatione et metamorphosibus insectorum Surinamensium” carries only Maria Sibylla Merian's name. The image is public domain; the hand-colouring is still one person's hand.
What to Take Away
Next time you stand before a flowering plant, give it three minutes: leaf arrangement, direction of the flower, the darkest patch. The flower of that year is dust, yet its image on paper has outlived every living cousin.
