Mike, if a plant has three old spike it doesn't neccessarily mean the plant had 3 flowers at once. A plant can hang on to it's old spikes for several years. If a plant does have more than one spike the flowers on those spikes may or may not open at the same time. Also, sometime a spike has more than one flower, together or at a separate time.
I have updated my site a little more. The
culturing at home page has been updated, I thought you all might like to read it.
