Here's photos to establish my 'bonadfides' as someone who actually grows the vine. I've had these for years. Every so often I have to trim the excess and donate to an interested fellow orchid grower. I've no idea how long they might be. I lived across the street from my present address, and originally had it in 1 pot, but it escaped and took over the back fence. When we moved, I took it down, and kept three large pieces (about 10 ft each), and re-started them in their current pots. The one on the left (top photo) keeps trying to escape the cage. These are not straight Van. planifolia, it is a primary hybrid with Van. bahiaensis.
