In a cocktail shaker filled with ice, combine the gin, dandelion syrup, elderflower liqueur, lemon juice, and sliced cucumber. Shake well until chilled and well mixed.
Fill a tall glass with ice and strain the cocktail mixture over the ice.
Top off the glass with the chilled club soda, stirring gently to combine.
Garnish the glass with a fresh dandelion flower, a lemon wheel, and a long, thin slice of cucumber, if desired.
Serve immediately and savor the refreshing taste of a Maine summer evening.
