Celosia (Celosia argentea), which is also known as cock's comb flower, is quite well known among florists in Indonesia because of its pretty charming colorful flowers. The types of Celosia commonly grown here are the cristata and plumose varieties.
Celosia for cut flowers can be planted outside or in a greenhouse or shade house. Planting outside the shade house will be quite high risk, especially if it is exposed to rain too often. Planting outside the shade house needs more because there is a possibility of damage to the plants due to heavy rains. The potential "disadvantages" of planting outside a shade house can be compared to the cost of building a shade house.
