Ipomoea leucantha

Twelve ways of seeing

• measured cast yellow-green
• upright 1.73 : 1
• published 1781
• Plate 301

Not a catalogue entry but a way of looking: how to stand, what to notice, how the line was cut, when it flowers, where it came from, who made it — and then the poems and the classics that taught China to see the same flower. Read the twelve in order and the plate opens.

1. 01

   First Look

   六法者何？一、气韵生动是也；二、骨法用笔是也；三、应物象形是也；四、随类赋彩是也；五、经营位置是也；六、传移模写是也。

   —— 南齐·谢赫《古画品录》

   The six laws: spirit resonance alive; bone-method in the brush; matching form; colour by kind; planning the placing; copying the masters.

   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 the darkest small patch: the whole tonal order is measured from there. The pose leans left: the upper half carries 17 points further left than the lower — a living thing, not a diagram.

   Name and Thing

   The binomial is Ipomoea leucantha: 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 擬紅花野牽牛 is a modern rendering of the Latin, not an old garden name.

   Form and Colour

   Measured on this plate: flower colour covers 12.2% of the sheet, foliage 0.0%, the cast yellow-green. 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.No colour group is recorded. A single plant, laid out with nothing hidden.

   Composition

   Tall and narrow, the plant rising in one movement with generous margins — the upright format of most floras. (about 1.73 : 1) No details are appended: a plate for looking, not for keying out. The plant covers only 13% of the sheet, centred near the centre; the emptiness is where the eye rests. Cover the margins with your thumb and the plate suffocates; uncover them and the flower breathes again.

   Line and Colour

   Eighteenth-century plates are mostly copper engraving: hatched lines for shadow, then hand-colouring by another hand. Craft leaves franker evidence than inscriptions.

6. 06

   Season

   Late spring to early autumn, June through September; under glass they could be had from March. The year 1781 on the plate is that of publication, not of flowering — the gathering came a year or two earlier. The best time to read such a plate is its flowering season: three minutes under the tree explains what no text can.

7. 07

   Provenance

   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 volume was made in 1781-1793, when most of this knowledge came from living plants under glass.

   The Book and the Hand

   “Icones Plantarum Rariorum” was drawn by Nikolaus Joseph Freiherr von Jacquin and published 1781-1793. This plate is Plate 301. The image is public domain; the hand-colouring is still one person's hand.

9. 09

   Poetic Resonance

   春风入园林，万卉以艳争相夸。

   —— 宋·王十朋《和韓李花 其一》

   The poem gives the mood first and the picture supplies the form; set the line beside the plate and the corolla becomes its resting point.

    The Written Tradition

    会心处不必在远，翳然林水，便自有濠濮间想也。

    —— 南朝宋·刘义庆《世说新语·言语》

    Where the heart understands, distance is not needed: a screen of trees and a little water, and the mind is already by the River Hao.

    China had its own gardening literature — Chen Haozi's Hua Jing on courtyard planting — which, like European bedding, brought wild plants down to human scale. Keep the line; it will surface the next time you meet the same plant.

    Symbolism

    Bedding plants carry no imperial weight; they mean the everyday — window sill, border, festival, gift. Victorian floriography grew up among exactly these flowers. In a flora it is a species first and a symbol second; the order is worth keeping.

    What to Take Away

    Appreciation is not knowledge but habit — one more look each time. Two centuries on, the plant may still flower in some garden; the one on this sheet stopped in the season of 1781.
