Phoebe is the herb witch who keeps the botanica — an elderly Afro-Latina woman with a grey braid, a terracotta shawl, seed packets in her apron and a small teal glass potion bottle on a cord. These are the concept renders of her: the shop counter, the drying rafters, the ground altar, the cauldron, the garden gate.
