The Flowergirls

Origin
Painted around the 1870s, this depiction of two young girls collecting flowers, titled "The Flowergirls" was painted by Harold A. Engebert using his nieces as models. An avid gardener in his spare time, Engebert's love of both hobbies coalesced into a single work that personified both art and horticulture.

It was in the possession of Henry McLaren, 2nd Baron Aberconway when it was snagged, and it was one of the last artifacts collected before the Warehouse's official move to America. It is currently located in the Warehouse garden.

Effects
The effects of the artifact only manifest when placed around growing plants. The specimens nearby tend to grow much lusher and more vibrant than normal due to an inexplicable rise in nutrient levels in both the soil and water. The painting also enhances the aromatic qualities of all forms of flowers.

In exchange, the painting requires a sort of sacrifice in that it takes the most vibrant and pleasing specimen around once a week and causes it to immediately wilt. The flower taken will then appear in the basket of the girl in the painting. As long as the painting is not robbed of it's sacrifice, it will continue to cause the plants to thrive.

If the "chosen bloom" is removed from the painting, it will react sourly. Nearby plants will wilt and die and the smell of rot will emanate from the painting. Furthermore, if deprived of any plant life the paint will begin to crack and peel. It does not seem to react to water, humidity or any other forms of wear.
