Circa 820

Sixteen beds beside the infirmary, each with its plant named.

The Plan of St Gall is the only architectural drawing to survive from the early Middle Ages. Among its buildings, beside the infirmary and the physician's house, it shows a small rectangular garden divided into sixteen beds — and it writes the name of a plant in each one. The drawing calls it the herbularius.

Nobody knows whether that garden was ever dug. What survives instead is the writing around it: a pharmacopoeia copied at Lorsch around 795, a poem by an abbot who kept his own garden at Reichenau and described every plant in it, and an imperial order listing what was to be grown on every royal estate.

This is what those texts say, plant by plant. It is not what they are right about.

Every bed is planted. A bed is filled only when one of the founding texts names the plant and a plate old enough to be out of copyright exists to show it. A red mark means the leaf carries a warning.

Caution — this plant is genuinely dangerous. The leaf explains how.

Why so few plants?

Because these are the ones the founding texts actually name and the ones for which a public-domain plate exists. Adding plants the sources do not mention, or illustrating them with a modern photograph or a generated picture, would make a longer garden and a worse record. 16 leaves that can each be checked are worth more than eighty that cannot.
