Blue Flax and Fairy Flax — Vintage Botanical Postcard

This postcard reproduces a 19th-century botanical plate of flax: the blue-flowered common flax (Linum usitatissimum) on the left, and the smaller, white-flowered fairy flax (Linum catharticum) on the right, each drawn down to root and seed detail.

Two species on one plate make this an efficient pick for a herbarium-style collection.
