If you got it where I think you did, it might flower for you pretty quickly. I got mine in May, the 11th I think. I noticed the spike 6/29/18. It is still working on it but there are finally buds showing on the tips of the spike.

So it was fast to put up the spike, but it sure is taking its sweet time about finishing the scape! Haha.
Happy growing,
