quick rebloom
Good news... my den phal diamond x cherry song which I purchased in bloom in September has bloomed again.
Bad news... the blooms are upside down! (it was under lights) |
Nice!
|
upside up you mean. Non-resupination has occured (if that term exists). Most orchids including Dendrobiums are resupinate which means that their flowers make 180 degree turn before opening (anthesis).
So your buds maybe didn't turn, -Or more likely the buds were formed upside down to begin with and when they made the 180, the flowers look upside up. |
I just hope they don't make this a habit.
|
Sometimes these things improve with time. Good luck!
|
Some of my dendrobiums and mini multi-branching phals do the crazy twisting thing, but only a few flowers, so I don't mind it.
It would be funny if all of the flowers were upside up. By the way, I don't think I understand upside up. hmm |
Because most orchids have resupinate flowers, they are actually already upside down. So, what looks upside down to us is actually upside up. In anycase, thats not really improtant, I guess point of view.

Ok, I think I get it now as I am looking at a few buds on my dendrobium (the phal type).
The protruding structure (don't know the technical term for it) on the buds point up while buds are still developing, and when the buds open up, the protruding structure do make 180 degree turn and point downward. How interesting! Do you know why they do this? any purpose??? By the way, my dendrobium Thongchai Gold has one flower upside down (to our point of view) while the rest of 16 flowers are perfectly oriented, again, to my view point. lol |
No I don't, but I can guess;
I would say that since the flowers have to orient themselves with the lip (labellum) pointing down so that insect pollinators can land on it, the flowers turn. Its all due to the fact that the flowers are bilaterally symmetrical (like us, with only one plane of division that yields two mirror images), and with a modified petal (the lip/labellum). If the flower were like an iris, it wouldn't need to turn, as all sides look the same. |
Well mine are uniformly wrong. They wanted to point their lips at the light. Maybe I should put a mirror under the pot next time they bud.
