Autumn colours
A stamp issued by Guernsey in 2016.
This SEPAC issue is a series of four stamps and named THE FOUR SEASONS
This one is autumn.
SEPAC = SMALL EUROPEAN POSTAL ADMINISTATION COOPERATIONS

Now to find an article in THE MEDITERRANEAN GARDEN which would be ideal to go with a stamp from Guernsey, not a Mediterranean country, and autumn colours.
After a long interesting and complicated search I came across
