Wilsons Farm has its own local asparagus today. Most years they run out by late Saturday the first weekend they have it, so don't wait till Sunday. It's heavenly!
Wilsons will not have tomato plants out for sale until mid-May but can get patio planter tomatoes out of the back greenhouse for you if you promise not to leave them out at night. Lexington Gardens has about 6 or 8 varieties of tomato plants (including brandywine) but these too are not ready to be left out at night, although they are less solicitous about making you promise to treat them right!
