(Alcea rosea) This single hollyhock was described in 1629 by English botanist John Parkinson as being “of a darke red like blackblood.” It 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.
