Ranked No. 1 in the flower potted plant sales chart, selling a million plants a month

I bet you can guess from the title which flower sells over a million plants a month. That's right, it's the rose. Only roses can have such astonishingly huge sales. At one site, a single store's rose seedlings had a monthly sales volume of 239,996 orders. Are you shocked? With such enormous sales, how does the shop grow them? I took screenshots of the top five sales figures, and they all show numbers that are shockingly high
