personally i prefer finding someone experienced if you can, looking online you can find tons of reputable blogs, groups, and guided workshops/classes. you can also contact professors. otherwise, for local resources, check your local bookstore/library or one in an outdoorsy town nearby. typically there's a section on local flora and fauna. reputable nurseries, historical sites, and seed farms are also a wealth of knowledge. some of the first books i got myself are forage harvest feast by marie -
viljoen & identifying and harvesting edible and medicinal plants in the wild and not so wild places by steve brill et al. there's a third i forgot the name of (googling but cant find it rn 😭) but i'm out of the country. a lot of my plant knowledge came from friends, parents, and later on coworkers when i began working in remote areas and we'd forage to make meals a little fancier
if it's still warm out for you one of my go-to recs is foraging pineapple weed! they're pretty common on hiking trails (they love to grow in compacted soil. they also grow in driveways, parking lots, construction zones etc. i find them all the time around ranches! but please don't pick any from those places 😭) just check if the area uses pesticides. if you crush the buds they smell like mix of pineapple (hence the name) and chamomile. i prefer making them into cookies but you can also use them
