potting shed

Kenyon had not picked up all his pretty expressions in the potting-shed; he was intimate with a boy who went to a public school.

I watched him cross the lawn and presently bring back a ladder from the potting-shed.

He left the hot, sweet air of the big hothouse and threaded his way among the glittering glasshouses to the potting-shed.

A potting-shed, a rag-and-bone shop, a pawn-broker's, or a thieves' kitchen?
