All,
I've been asked several times recently what a spike for either Cattleya walkeriana or nobilior looks like. Turns out this is the perfect time of year to ask such a question! Check out the spikes on a some nobilior, walkeriana, and Brazilian Jewel (nobilior x walkeriana).
Here's a video showing my current spikes in the greenhouse:
