From The Flower Expert:
Cockscomb flowers are also known as Wool Flowers or Brain Celosia, suggestive of a highly colored brain. The flowers belong to the amaranth family, Amaranthaceae. Cockscomb bloom with a compacted crested head 2-5 inches across, on leafy stems that are 12-28 inches long. The flower’s name is suggestive of a rooster’s comb. Cockscomb Flower blooms from late summer through late fall. The Celosia plant is an annual dicotyledon.
The cockscomb we have were given to me by an Aunt in the summer of 2010. They came up really late this year and we’ve practically forgotten about them. Notice the description above says they are an annual, but ours came back and some in a bed outside my work came back also.
They are quite an unusual plant and do remind me of a brain or of a rooster. But they are very pretty right now. Just lost in the back flower bed. But I notice they’ve also spread quite a bit, so last weekend I dug up a few of them and moved them to a more prominent spot just to see if they will come back again next year as well.
I hope they do because they are so colorful this time of year when everything else is yellowing away. You also have to catch these in the nurseries early in the year, despite the fact that they really don’t take off until late summer.
