Gooseberries. You hate 'em or you love 'em

These little green orbs are kissin' cousins to the currant, and like their relatives they can be welcomed or reviled in the U.S.  They make great pies, jellies, jams, and sauces for the table, but they can also transport a destructive fungus called 'white pine blister rust'.  If your locale doesn't feature white pines then gooseberry bushes might make a good berry bramble for you, especially if you like your sweets a little on the tart side.
