Demeter's Bouquet

Origin
Demeter was the Greek goddess of the harvest, presiding over grains and the earth’s fertility. Her daughter Persephone was stolen away to Hades’ underworld and ate its pomegranate seeds. A pact was reached where she could return to the earth every spring to see Demeter, but Persephone had to return six months later, during the wintertime.

Effects
When exposed to vegetation, it increases their growth three times the normal rate. However, any plants affected wither away during the winter months.
