It's another unstaked spike, but this one holds it's self very upright rather than trailing down. Very waxy flowers, and the spike is very strong as well.
I have one that looks exactly like that! I got it at Lowe's.
I got a rebloom on it this year shortly after finishing a previous bloom. One new spike, and a few short spikes coming off the old spike...even a lengthening of the old spike with four flowers at the end of that.
