Not really at all familiar with these. This was a pair of cuttings I received around November, poked them into bark, and they seem happy enough. I'm given to understand this cane won't bloom again, but should set new canes and/or keikis. The parent plant was growing terrestrial and froze December. What insects pollen are these? Just wondering if I could get some seed to volunteer, as I understand that they are wont to do.
These grow a stem vertically for a while, then send up a flower spike from the apex. It flowers, then the flowers drop off. After flowering the old stem can remain alive for many years. That stem makes new growth from the base, and usually also makes new plantlets from farther up the stem. All the growths are capable of flowering if they are large enough. These can grow into a tangled mass of stems and flowers.
The plant you show is a little out of focus, but that appears to me to be a developing bloom spike. It doesn't look like it flowered in the past. I think you'll have flowers soon.
I've seen bees and hummingbirds visiting the flowers. Most people who can grow these outside regularly get fruits.
