If you grow DutchFem Special inside then it can still become pretty tall, about 120-150 cm (3’7-4’5 feet.) But if you grow this plant outside then she can become, under the right circumstances, become 300cm tall! (9 feet!) She grows best in a warm Mediteranean climate with a lot of sunlight. This plant will also grow good in a somewhat cooler climate such as The Netherlands, Germany or England. That has to do with her short flowering period.
