Flower delivery giant FTD has quietly acquired BloomThat, a San Francisco-based startup often referred to as "Uber for flowers," according to multiple sources.

Word is that the deal was for a small amount of cash, but neither TD nor BloomThat returned requests for comment.

BloomThat had raised $7.5 million in VC funding from firms like Forerunner Ventures, First Round Capital, Initialized Capital, Rothenberg Ventures and Sherpa Capital. Neither FTD nor BloomThat returned requests for comment.
