In blender, add 1/4 lb strawberries and orange blossom water. Blend until smooth. Taste and adjust sweetness with honey, if desired. Into small bowl, strain strawberry purée through fine-mesh sieve. Discard any pulp left in sieve and set aside.

Cut remaining strawberries into thin slices, lengthwise. Arrange them over chilled serving plates in a single layer, slightly overlapping. Drizzle with a few spoonfuls of strawberry purée before garnishing with a scattering of pistachios, mint leaves, and edible flower petals.
