Hello again,

Unfortunately, you cannot use OpenStreetMap directly for personal notes or locations. The data from the map is visible to everyone and used by many maps and applications. For example, someone looking for a florist shop will find this location. So you should only add correctly specified/tagged objects. At this time, OSM does not tag flower patches and most historical features, so I cannot suggest any replacements. It's always possible to add new custom tags, but they wouldn't show up on the map anyway.

If you want to use OSM as a base map for personal notes, there are various websites and apps that can do similar functionality, for example https://umap.openstreetmap.fr/en/
