This is sorrel. Do you know it? It's a hardy perennial that can be used as a salad green, which is why I planted it. Here in zone 6, by the end of March it has usually revivied enough to start spiking salads with its lemony/sour flavor. Later in the year I cook it with spinach, or make sorrel soup.
I use fallen leaves as mulch in the veggie beds - a tip that I picked up from my sis-in-law, Sue. My son "helped" me take the leaf cover off, and what did we find lurking there? A few mache plants (pronounced "mosh" - aka lamb's lettuce, aaka corn salad) planted last fall and apparently forgotten. That mache is some tough stuff.
Another surpising find under the mulch - the chives are sprouting. Well, beyond sprouting and into sprouted. The garlic chives are a little behind them; nothing photogenic yet.
And finally, another perennial (ha, ha) favorite - alpine strawberries. These little fellas rival mache for their toughness. Can you see the reddish crown? By June the plant will be making tiny, fragrant berries continuously until late October/early November.
That's it for now - but all in all, not bad for a very early spring garden. Off to read seed catalogs, and dream.
