I bought some orchids August 23 from an orchid grower. They were blooming when I bought them. I had one phalaenopsis that dropped all it's flowers after over 2 months in bloom at my house, and it started to spike again before the last flower fell off.
This plant has kept almost all it's blooms, and yesterday I noticed that the tips of the spikes are starting to grow again!!!

Does this happen often? Can I expect this to happen with this plant again?
How long is anyone's longest blooming plant??
