Overview: When an unusual plant arrives unexpectedly in Gordon’s garden, Gordon assumes there’s been a mix-up in the Gnome Post. But Percy, Rosie and Jerome aren’t expecting a delivery either, so Gordon sets off with Andrew around the world, to return the plant to its proper home. In each location Gordon discovers clues as to the plant’s natural habitat - whether it likes hot or cold, dry or wet climates – and they soon find the owner. But the Chief Gnome is hot on Gordon’s heels looking for the plant too - it’s a surprise present for his wife Gladioli’s birthday.
