Hi cham101, sorry for the delayed response. Sigh, I actually do have some decent images from my foraging last year, but they're on my FUBAR lappy. However, I will try to get a reader to pull them off the HDD tomorrow. When I was foraging, it was well into fall, and perilla (or beefsteak plant) was right at the limit for picking. Once the seed pod bursts, apparently, the leaves no longer taste as good. Now this is info via my mom, so take it as you will. Right now you may still be able to find some ramps, but I haven't had time to go out and check the patch I know about. I know for sure that there are wild strawberries to be found, on the footpath at Lake Roland for one, along some of the paths at Prettyboy as well. I do have some pics of perilla I just found on my email, which I've attached. You can see there was a ton of it growing along Dulaney Valley Road.
Epazote grows all over the place, and I'll keep my cam on me tomorrow in case I come across some. Finally, there is wild asparagus, which should be ready to harvest right now, but I have yet to find any around here. I've heard that it grows along Rtes. 40 and 70, west of the beltway. Speaking of which, "Stalking the Wild Asparagus" by Euell Gibbons is more or less the bible of foraging. And then of course there's Steve Brill, who I think was profiled in the Sun a few years ago.
I plan on exploring the Korean side of found food more this year. I just think it's a crazy coincidence that such parallel ingredients exist so far apart. Well, maybe not so crazy, since we're talking about parts of the world that are both covered in deciduous forest (the best kind!), and people tend to emigrate to places with climates and geographical features similar to home. But I digress....
