Draw a horse-chestnut leaf in Aquarell: gather seven leaflets at one petiole tip

A horse-chestnut leaf can be mistaken for one serrated blade or seven leaves along a twig. In Aquarell, choose the common seven-leaflet form and draw one shared petiole, radiating leaflets and individual midribs. The reference species is Aesculus hippocastanum; seven is the chosen form, not a requirement for every real leaf.

Choose one seven-leaflet compound leaf

Use an approximately 1600×1800 px portrait canvas with a gently right-leaning subject and room for the complete petiole. Mark its terminal junction and radiate seven leaflet axes, longer centrally and smaller toward the sides. Count paths before blades. Tighten the basal cluster if it looks like seven branches; vary lengths if it resembles an even fan. Positions and proportions are original composition choices, not natural dimensions inferred from pixels or a claim that all specimens share the usual count.

Keep the petiole single until the junction

Draw one continuous petiole up to the junction, then narrow leaflet bases. Do not distribute leaflets along its length, which would suggest pinnate arrangement. A near leaflet may partly occlude the centre, but central and side attachments should remain traceable. Tighten overly long independent stalks and repair a petiole broken by shadow. Omit twigs and axillary buds so petiole and branch are not confused, and invent no hidden tissue section.

Give each leaflet its own complete blade

Build seven separate blades around the axes, wider above narrow bases and each ending in one tip. Keep background gaps between them toward the junction rather than making one continuous seven-pointed blade. Decide small overlaps before merging the centre into green. Recover a hidden leaflet if only six read; inspect teeth or curled edges if eight appear. Vary length and width instead of cloning identical stickers for neatness.

Assign one midrib to each leaflet

Run a midrib from each leaflet base to its tip, with secondary veins spreading to its own margin, never across background gaps. Establish the central blade first and rotate vein patterns for the sides. Revisit individual axes if all veins point straight up on screen. Reduce contrast and taper ends if veins resemble branches laid on top. Seven midribs converge regionally without a single net across the image. This is explanatory venation, not a vein-by-vein scientific plate or automatic growth recognition.

Let teeth follow each blade orientation

Preserve large contours before adding small serrations, clearer near and abbreviated far, rather than equal giant sawteeth. Keep each principal tip distinct from minor teeth. Restore gaps if serrations fuse leaflets. Shorten hairy edges and connect tooth bases to blade tissue. Tooth count is no identification test; only the margin category is referenced. Tone should describe blade orientation instead of turning every tooth into its own disconnected light/dark block.

Keep seven leaflets countable through gaps

Use warm-grey ground and related greens, with a slightly lighter centre but no forced symmetry. Inspect the six main inter-leaflet gaps, noting narrowed overlaps and openings reaching the bases. Hide occluded veins; reduce far saturation without erasing a whole blade. Reopen mistaken green connections with background if the leaf reads as simple, rather than labelling seven parts. Distinguish petiole shadow from real gaps. Restrained edge light is enough without identical white outlines.

Check the common junction and separate blades

Hide veins and teeth, follow the petiole to one junction and identify seven separate blades. Repair arrangement if leaflets grow along the stalk, gaps if seven tips share continuous tissue, and occlusion if only six remain; do not add an unattached leaflet. Restore details and verify midribs end at their own tips without crossing margins. Note horse-chestnut and the seven-leaflet form; observe five-leaflet specimens anew. This checks drawn connectivity, not complete taxonomic identification.

Count back to the base after reopening

Save native work, hide axes and numbers, export PNG and reopen. Count leaflets and the shared petiole at small size, then inspect accidental green bridges and branch-like bases enlarged. Recover a lost side leaflet through contrast or minor recomposition rather than darkening every vein. Revise the original, export again and reopen editable layers. Record one compound leaf without fruits or twig. Verify leaflets, junction and midribs, not edibility, tree age, dimensions or every species character.
