Crystalline vases
Crystalline vases, faceted columns of transparent, flawless stone, comprise a set of three special artefacts. Each is sold by its colour: a pale pink calla lily magically blooms from a white vase, a blue vase generates a cluster of indigo hydrangeas, and a violet vase holds an amethyst magnolia. Unlike clay flowerpots, only one flower grows within a vase at any given time, but a new one begins to sprout if the old is removed. They regrow once per Achaean day if picked regularly.
The flowers that the vases contain cannot be found growing anywhere else in Achaea. The vases were once sold at the Shop of Wonders in Delos, but they have since been discontinued.
