It means a natural talent for gardening, a person's special ability to make plants grow well. Either its origin is linked to King Edward I of England, who enjoyed fresh green peas so much that he had half a dozen serfs working to keep him supplied, a prize going to the one with the greenest thumb; or it comes from the fact that repeatedly handling clay pots encrusted with algae will stain a gardener's fingers green.

Übersetzung:

einen grünen Daumen haben
