Euthane/Vanda Sanderiana bloom

[eri789]

I purchased my Waling-Waling a few years ago online from a grower in Thailand. This is the second year it's bloomed and although it's beautiful I'm not sure about a few things.
I live in South Fl & have it hanging in the north west corner outside of my home. It receives full morning sun and i water it almost every other day or at least twice a week. I also fertilize twice a week with Green Jungle Orchid food(1-0-1).
I consider myself an orchid noob, especially with taking care of this plant because it's so hard to find relative care info online. One site will say one thing & another will say something different or only give vague/general info.
Back to my question.... If you take a look at the pictures you'll notice the lower petals are bent backwards & look slightly tinted, they are also stiff and feel rough. Is this normal? It happened last year as well but was a little worse.

Sorry I can't help with the question, but this is gorgeous Vanda and gorgeous blooms!!!

Gorgeous!
Hopefully another member can answer your questions!

Is there some kind of damage on the flowers?
I see brown edges on the lower petals.
That said, I believe this is not an easy species to grow (and get it to bloom)

Here is David Genovese's V. Sanderiana

Maybe it has extra genes...a 4N plant (2x the genome in each cell) has larger flowers, and offspring will have less than 4N but more than 2N (the 'normal' amount for this species)

The leaves look fine so I would say it's not fungus or a virus, just a unique plant.

I have had a sanderiana alba for almost a year but it is just a seedling, I am hoping it will be big enough by next fall!

Lovely, sorry can't help with the questions.

I bring my orchids indoors when it spike. The flower when it opens its blooms outdoors can have a brown tint on the edges and curl back when it has a moisture issue. Sometimes bugs sucking on the nectar while still a bud also affect the flower when it opens.
You have a normal Euanthe sanderiana....the leaves are opened and it has the right shade of green(meaning you are giving it the right light)....closed leaves means you are having a light or humidity issues.
The flower color and form is typical of a classic 'Waling-waling'....
*you are lucky to have this for it is extinct in the wilds....maybe a couple of plants have been sighted on one of the trees in a remote mountain range of Mindanao where it is endemic to.

*TIP: feed it fertilizer only once a week not twice a week as you are doing=this can have crystal deposits on the roots that browns it and will not absorb moisture as it should= you always liberally water this plant and make sure the roots get flushed of those crystal deposits....you may water it everyday if it is above 90F in your environment....you can place it gradually in direct sun or preferably a south facing shaded bright sunlight.....this is an equatorial plant that grows on tall trees and the tallest I seen is 7 feet....my 11 year old plant is now 5 feet tall and the longest roots is 4 feet.
I have four keikis from the mother plant and two of them are now in separate baskets. I left the other two with the mother.


This is the oldest keiki the very first that the mother plant gave me, it is in spike. This keiki is now 28 inches tall and 3 feet root length

Thank you so much for your time & praise.
Also, Bud thank you for the advice. I will definitely start changing my watering & fertilizing schedule & bringing it inside when it blooms. Your keiki are beautiful as well.

Looks hybrid. Pure species doesn't have spur at the back of labellum. Check pic #3.
