Flame Nettle in a Flowerpot

Flame nettles—coleus plants cultivated for their vivid multicolored foliage rather than their flowers—offered Van Gogh an unusual opportunity to study how color functioned in leaves alone, without the conventional prettiness of blossoms. This 1886 canvas at the Van Gogh Museum shows him drawn to the plant's complex patterning of red, green, yellow, and purple within a single leaf, which presented a natural demonstration of the color juxtapositions he was studying through Impressionist theory. The potted plant subject is humble but visually intense.

The variegated foliage demands considerable chromatic precision, with adjacent zones of contrasting color on single leaves requiring careful calibration to read as belonging to the same plant. Van Gogh's strokes follow the leaf forms, their direction reinforcing the organic structure while the color juxtapositions demonstrate the vibrancy achievable through unmixed complementary placement.
