It’s a closely guarded secret among more experienced gardeners, that on certain nights, shrubs will sometimes lift themselves from their flower beds and wander abroad in the night air, keen to experience the freedom accorded members of the animal kingdom. Most of them don’t travel far. Very soon they experience a great homesickness for the soil they have lived in all of their lives, and by daybreak will be back in their beds, so neatly position that few of us notice they’ve moved at all. However, occasionally a more adventurous plant will travel further and become lost. With very little idea of direction beyond the narrow confines of its garden or woodland corner, compelled by some unknown atavistic impulse the shrub will then head for the coast. On arrival it will bed down on the shore and begin a new life, by day surprising tourists by its mere presence so close to the watery margins, and in the evenings whispering tales to its seedlings of its former home.
