Can't speak from experience with the species - I did get a seedling, but it has some growing to do.

I'd wonder if the 10 spikes might split off the plant's energy and each would progess slower accordingly. I do know that repotting can set back spike and flower development. I got some divisions from a friend this summer, and I repotted them once I got home. Probably more important than the repotting was the change in growing conditions. Mine bloomed two months after hers did - from the same plant.

Patience, Grasshoppa!
