(Alcea rosea) Grown by Thomas Jefferson at Monticello, but mentioned even earlier in 1629 by John Parkinson, who described this single hollyhock as being “of a darke red like blackblood.” Appears black on overcast days, but will have a hint of red in bright sun. Plant next to a white fence for a spectacular contrast. Self-seeding biennial, 5-6' tall.
