Hollyhocks raised in greenhouses by the Texas University botany school grow an average of 20 centimeters per year, while hollyhocks raised outdoors by the Florida University botany school grow an average of 14 centimeters per year. The annual growth rate of the average hollyhock is 17 centimeters per year. If a hollyhock originally planted outside by the Florida University botany school is transplanted and moved to the greenhouses run by the Texas University botany school, the hollyhock's growth rate will be greater than it would have been.
