It would depend on where you are located/zone/weather, but yes many varieties of celosia are perennials - weather permitting.

Dave

thank you very much for the reply. i usually start watering the plant around this time after it has remained in storage ie room temp without any water. i dont bother to remove the dried flowers when dries up for a while to re sow the pot. the plant does go outside when the wheather is warm enough to get full sun up until september or october. i usally get the fiery bush variety but i did see 2 small combs twice.

is there any trick to producing the combs? i do pinch off dried segment to get it to regrow the usual appearance. i'll often get around 10 full grown plants and 5-6 reblooms after the initlal blooming. i dont really bother stealing the seedling for seperate pots BC i have enough different plant species alive at any point of the year.

i live in montreal where the temp isnt perfect year round but the plant stays inside when its too cold.

I live south of you and have celosia seeds germinate all over my garden every year, all different kinds. I pull up the ones that are in the way or too weak and not nice looking. I have some red feather ones that reach over 6 feet tall (which I got originally from street planterbox seeds I took in Cooperstown, NY ten years ago!)

Some of the plants need to be staked to keep them from falling over. If you have to grow them in pots, maybe you can rig up some kind of cage or trellis to tie them to. The brain shaped celosia just naturally bend over sometimes. I don't grow them.
