Some one forgot to install a teleprompter in the Whitehouse garden cause when she spoke........ we are going grow herbs, beans and LETTUCES! thats right you heard it right LETTUCES. Harvard grad major in liberal arts and ebonics. Can’t make this stuff up folks!
LETTUCES is correct if more than one type is going to be grown.
The collection of crops, a wishlist from White House kitchen staff, will include lettuces, squash, fennel, rhubarb, cucumbers and sweet and hot peppers.
More than one kind of lettuce = "lettuces"
