Draw bok choy in Aquarell: connect thick petioles to blades and the base

Bok choy’s white or pale-green petioles are not separate white sticks. They support blades and converge into one plant base. Use an invented appearance with five visible leaves to check cupped stalks, blade spread and occlusion, not a universal leaf count. Organise structure manually in Aquarell, then add restrained veins. This is still-life drawing, not cultivation, cooking or food-quality identification.

Establish the base and five visible leaves

Use an approximately 1600×1900 px portrait canvas with warm grey-cream background. Put the base low, outer leaves spreading and shorter inner leaves central. Sketch a small base envelope and five axes, labelled outer-left, outer-right, rear, inner-left and inner-right. Separate sketch, rear leaves, petioles, front leaves and shadow. Do not bury every axis under green blobs; trace all five to the base region. Remove a vase-like white container if present or vary depth if fan-like rather than changing angles alone. Five describes visible leaves here, not the plant’s total count.

Give thick petioles cupped faces

Make pale petioles broader near the base and slightly narrower toward blades, suggesting a cupped near face with soft grey-green and modest lighter edges, not hard white rails. Solve outer-left first as a broad thick channel rather than a round rod. Check width and blade connection if celery-bundle-like, or add modest edge depth if ribbon-like. Vary visible inner/outer surfaces rather than copying a central black groove everywhere. The cup is a volume cue, not pixel-based tissue measurement or a reason to cut open every stalk.

Continue petioles into midribs and blades

Continue each petiole into a paler midrib and expand the blade on both sides with modest edge undulations. Avoid a stalk abruptly ending at a green blob or a midrib floating off the blade. Establish broad blade shape, then turning midrib and only two or three quiet side veins. Repair the gradual transition if white-stick/green-cloud-like. Check base-to-midrib continuity if separate tree leaves seem pasted on white stems. Use muted deep green with slightly lighter inner leaves if desired; these choices establish composition, not leaf age, cultivar or nutrition.

Share the base without a black knot

Let front outer leaves conceal some inner petioles and hide rear roots behind them while retaining five sketch paths. Use a small pale grey-green base shadow rather than black rings around every root. Gather and occlude separate-looking plants, or recover near petiole edges if the base becomes an exitless white mass. Hide blades to inspect stalk paths, then restore and check correct pairing. Not every root must show, but one visible petiole must not inexplicably fork into two separate leaves.

Model blade bends with broad values

Light upper left, warming lit blades and cooling backs or occluded areas. Give the outer-left leaf one downward curl if useful, tracing its midrib to the correct stalk so it does not become a sixth leaf. Soften selected edges and reorient broad planes if cardboard-like rather than adding dense veins. Reduce black wrinkles if cloth-like. Pale stalks and green blades share light, not identical white centres and black sides. One or two curls are enough; identical folds everywhere obscure the plant’s overall upward spread.

Keep veins within their own visible blades

Add selected side veins from the focal midrib, fading toward edges without crossing front leaves into rear ones. Keep petiole grain lighter so pale areas do not become grey barcodes. Hide details to verify five leaves and thick stalks, then restore only useful lines. Quiet secondary veins if textbook-diagram-like or remove contrast specks if dirty-looking. Sources support basic blade/thick-petiole form, not an organ identity for every line. Disease marks, holes and droplets are unnecessary, and invented detail cannot establish food condition.

Audit stalk–blade pairing and support in monochrome

Save a vein-free monochrome version and trace five numbered base-to-tip paths, each pairing stalk and blade. Hide shadow to inspect a complete base, then restore tight bottom contact and softer outer-leaf shadow. Reconnect a floating blade rather than adding ground shadow. Vary local width and gaps if pale stalks merge into one column. Adjust one axis or occlusion without simultaneously adding leaves. A changed visible count needs a separate version and revised wording; do not silently decorate the stated five-leaf exercise with two extras.

Keep pale stalks distinct from background in export

Save the layered original and inspect base, outer-left curl and five stalk–blade joins in a PNG at use size. Separate pale stalks from background locally through temperature or value rather than outlining the plant black. Reduce vein count and contrast if net-like. Record a fault such as rear midrib crossing a front leaf for layer repair. Judge thick petiole support, common base and depth, not maximum green darkness. Sources constrain plant identity; five visible leaves, pose and pixels are drawing choices, not cultivar identification, cultivation testing or food-quality acceptance.
