A two to three-week leave in the 2017 installment, Earthly Remains, by Donna Leon allows Venice's Commissioner to appreciate namesake Guido Brunetti gardens as derivative Donna Leon gardens for Fathers Day gardenscapes.
The gardenscape of edible, herbal, ornamental, woody plants on Sant'Erasmo (Saint Erasmus, 240?-June 10, 303?), the Venetian lagoon's market garden island, belongs to Guido's Falier in-laws. It centers upon a churning "sea of flowers, only flowers, growing in reckless abandon and with no apparent order, not of variety, colour, height nor size." Commissario Guido Brunetti mystery series number 26 divulges few guidelines other than that "Colour ruled, shapes stood where they pleased, yet the whole was strangely harmonious."
Like the derivative cookbook and walking tours, Guido Brunetti gardens emerge from enumerating plants and their products employed, enjoyed and espied by Venice's practical-minded Police Commissioner.
