I have two dozen cut roses, one dozen in a crystal vase, and one dozen in a Lenox ceramic vase. We're in a dry (70°F) heated house in the middle of winter, and the roses in the ceramic vase are far happier (less wilting) than their crystal counterparts, despite their identical light exposure and watering.
Is this a property of the material of the vase? Should I only put these roses in ceramic from now on?
These were purchased as two-dozen, and were mixed prior to cutting: The roses are identical in every way I can imagine, except for their vase.
[EDIT]: Some pictures!
To wit, the diameters of the openings (and the water levels) are the same in both containers.
