Vanilla orchid

My friend, Hélcio Amaral, gave me a cutting of Vanilla planifolia some years ago, right from his back yard. I planted it next to a taperebá tree (Spondias lutea) at the Bosque. Although it suffered during the dry season, it made its way up the tree at least 10 meters. Then it lost its grip and fell. The next rainy season it was climbing again. So it went for several years, never getting higher than that. I took some cuttings from the plant and placed them on the supporting columns of the porches. Local orchid collectors told me that they had never seen the plant bloom. The one in the attached image did. The flower coming up in the next post.
