Many of the species phals (equestris included) will continue to bloom from the same spike. I have one I got back in June that is still blooming from the same spike. It will also send out lateral branching spikes from the original spike. Don't cut it. Bellina and violacea are another couple that continue to bloom from the original spike. I think the cool night temps really do nudge them to start spiking. It's very exciting. Congrats & good growing!
