Wood Sorrel (Oxalis Acetosella) — Vintage Botanical Postcard

A vintage botanical illustration of wood sorrel (Oxalis Acetosella) — a woodland plant with delicate, pale flowers veined in pink above clusters of trefoil leaves. The engraving captures each leaflet and root in fine, scientific detail.

• Density: 350 g/m²
• Size: 10×15 cm

Its trefoil leaves fold shut at night, a small detail worth mentioning before the card is sent.
