I just looked into it and apparently they are 'legit' but it's very questionable.
Patio Plants is a website under Botanical Growers Network. They have a ton of sites...

I found this review from someone online
This is another iteration of Botanical Growers, which operates under a variety of names peddling tropical plants. Most of the time they say they are propagating, not selling. But every few months or so they announce a "sale" wherein they "open" their inventory online with prices, first come, first served. I tried to get some of their aroids through their "Ken's Philodendrons" ID. The online sale began at 8 a.m. By the time I got through at 8:20 everthing I wanted was sold out as was 95% of their other inventory. Then they told me and other buyers to come back for their next internet sale in 3 months. I said, "Forget it."
I don't know what BG's gimmick is and why they operate under so many names. Or how they manage to stay in business selling plants on the internet for only a few days per year. And their nusery(ies) in FL are not open to the public because they are so busy "propagating."
