Black Hollyhock (Alcea rosea) This is an old-fashioned single blooming classic, towering in flower gardens for centuries, including at Thomas Jefferson’s Monticello. Impressive black-chocolate/burgundy coloured flowers grow on slender stems. John Parkinson described Black Hollyhock as early as 1629 as being "of a dark red like black blood". Hollyhock is a biennial, or at best, a weak perennial that will flower in its second year.
