Now, the only problem is that this is not a petunia. Petunias are members of the genus Petunia (simple!) in the Solanaceae, the potato family. This is unfortunately a photo of a morning glory, in the genus Ipomoea in the family Convolvulaceae, related to sweet potatoes. There are several kinds of morning glories, all in the same family, and both morning glories and petunias come in a wide array of flower color patterns.
The very interesting research article has the right plant in its illustrations.

UPDATE 1: It seems that the wrong photo was first used by the renowned science magazine Science [!!!] in their highlight of this research. See their article titled "ScienceShot: Broken Pump turns petunias blue", dated Jan 2, 2014. So The New York Times probably just reused the photo provide by Science. Here is the screenshot:

UPDATE 5: New York Times removed the photo for their article and provided a correction on Jan 10, 2014. Thank you!
