Book recommendations for New Jersey / Lower Hudson / North Eastern US

Do you have any recommendations so I can become better at identifying?

I’ve become an avid iNaturalist over the past few months. I recently moved to the US, so 90% of what I saw was unknown and as I like to hike, I wanted to know more about my environment. I also volunteer for the NYNJ Trail Conference in their invasives team. For months, I’ve been seeing the same plants - the ones that are easy to identify in the winter. Now spring is marching on and there’s an explosion of new growth. What was previously a small unidentifiable sedge could be Pennsylvania Sedge but I’m unsure. How do I tell which bedstraw it is? I know iNat is good at giving suggestions, but it’s not telling me the finer detail, like the obvious differences between red and white clover or wild and invasive strawberries.

I’m mostly interested in plants, but also like to know about funghi and birds, well anything I’m likely to stumble across, but plants seems like the obvious place to start.

Thanks.
