In small saucepan, add maple syrup, orange juice, rosemary, and crushed juniper berries. Place over medium heat and bring to simmer, stirring occasionally. Once at hard simmer, remove from heat and set aside for 10 minutes, allowing flavors to steep. Strain syrup through fine-mesh sieve into bottle or bowl and discard solids. Syrup may be refrigerated in an airtight container for up to 1 month.
When ready to assemble salad, on serving platter, arrange persimmon slices, kiwi rounds, grapefruit segments, clementine rounds, pear slices, and pomegranate arils. Sprinkle lime zest and juice over fruits, to taste. Drizzle 1/3 of syrup over fruit; garnish with pumpkin seeds.
Serve alongside remaining syrup for self-serving, if desired.
