Once I purchased a house I had the same goal starting with my neighborhood. I started with the Seek app which allows you to take a picture of a plant and it will identify. I used it whenever I walk around my block and my house. Start with the ones you see the most. Start with plants since they are static and most common. Start with flowers since those are the most distinctive and easiest to identify via the app.

If you are really interested there are a few books that I found very interesting. First would be a foraging / herbalism book for your region. I can’t recommend what that is since I only know for the Upper Midwest in the USA. I found I could remember a plant best if I knew what it was for and could interact with it. (I.e. use it or eat it)

The second is Weeds: in defence of Nature’s Most Unloved Plants. If you live anywhere where other people live you will mostly see “weeds” the most human plant. The author is from England so it might not be about all your weeds but they are global travelers so you will see lots of overlap. It’s a fun long term project. Good luck
