This is very Alpha stages, but if this is the kind of thing you would use I would love feedback on the features you'd need to make it useful.

I originally built this to keep track of my rose garden (with currently 150 roses and counting, which are where) and my orchard (again mostly to remember which variety and year of planting). Several people asked me to make a public version, so now its public.

You can see a completed-ish design here: https://floracarta.com/design/vzqJ7UCrCSB8
