Purple Celosia

I do not know the variety of this particular Celosia. I bought it in a small pot from my local Stop & Shop, it did not have a stick in the pot to identify the variety. I promptly put this gem in my garden and all it has done is grow and grow and grow. This flower has been the mainstay of my Summer flower garden, quite a showpiece. If anyone knows the name, please do share with me.
