Thanks a lot Margie and Doris. The first week in October every year they put all the this cactuses in a greenhouse. And next year in june they plant them in the park again. They use 25 000 plants in this cactus park. Every year there are a special motive - this year NT 250 år - that means that they this year celebrate the lokal newspaper NT who is celebrating 250 year. You can see and read more about this Cactus Park here:
