My Urgandiae has had 46 flowers on two spikes, has 3 flowers right now and buds are still forming. Plus, there is a new spike!
A similar situation with my Phrag. Sorcerer's Apprentice. It has one main stem with two branches. They've produced 55 flowers in the past plus there are 6 flowers (2 on each branch) right now, and buds are still forming.
