A detailed black and white botanical line drawing of a yarrow plant with feathery leaves and flat-topped flower clusters.

A black and white botanical line drawing in horticultural style of the yarrow plant (Achillea millefolium), rendered in black and white. Illustrate a perennial herbaceous plant with upright to slightly spreading stems, growing approximately 30 to 90 centimeters tall. Depict finely divided, fern-like leaves that appear soft and feathery with many narrow lobes and edges that are lobed or toothed, arranged alternately along the stems. Show clusters of small, flat-topped, composite flower heads composed of both tubular disc florets at the center and strap-shaped ray florets radiating around the edges. Each flower head should be roughly 2 to 4 centimeters across, with about 6 to 10 ray florets and 11 to 20 tiny disc florets in the center. The plant should have multiple flowering stems topped with these flat, umbrella-like clusters. Emphasize delicate fine linework, detailed botanical textures of the feathery leaves, and strong tonal contrast typical of classic vintage scientific botanical illustrations. The drawing should have no background or roots visible, with the plant centered and isolated, shown from a natural frontal or slightly angled view to showcase the layered leaf texture and flower structure.
