Although iNaturalist allows its users to post observations of cultivated plants, they don't encourage it. It's intended to be a way of recording naturally occurring plants and animals. And that was originally my intention here, as well. So when I first set up the site, I only included plants that just showed up in the yard, which means weeds, mostly. Or volunteers, depending on how you look at it.
But I've decided to include all the other plants, as well. I'd like a list of all the plants in the yard, so I can keep track of their interactions with the yard's other inhabitants (mostly insects, of course).
