It can be a long list. Here are a few:
One of them is Den. Garnet Jewel that I bought last year. Even it's growing well with new canes, but no sign of spiking at all.
I have this doritis which I bought in bloom maybe more than 5 years ago. It has produced lots of keikis over years, but no bloom. The original orchid died, and so did the first two generations of keikis. The two great-grandbabies I have are now growing OK, still no sign of spiking.
