My wife is very much into gardening, but also habitat. She'll look up endangered butterflies, find out what plants they rely on for laying eggs, food sources as larvae etc. She'll plant them in a corner of the garden and like magic, we'll see those butterflies within a year or two. In some cases there will be an insect that relies entirely on a tiny number of plants, but those plants may also rely entirely on it, or on something else. My point being that except for cultivated and commercially available plants, ecosystems are critical. Much of our garden's flowers are wild. Commercial flowers usually provide pollen, but not habitat, which is why she focuses on wild native flowers. I'll ask her to try the app, but I'm gonna predict that it won't be much use for these.

Usually when she's looking up how to care for a particular plant she uses Kagi to exclude websites with a large userbase in the United States. She prefers websites that are UK/Ireland based, or to a lesser degree, Northern European (using Google translate). Why? Because of subtle differences in plant naming, species etc and wildly different climate. She finds advise from U.S. based sites to be extremely questionable here, and you might waste a whole year trying to grow something before you realise that the advice doesn't work here.

But hey, every British band in the 60s and 70s wanted to break into America because they're are hundreds of millions of English speaking people living in a single TV nation. It makes sense for you to focus your efforts there. And whatever AI is behind your app is likely to have been trained on commercial plants in the US.
