A few of my blooms are now wilting and they turn a bit pinker too. But I am quite positive it is not dyed. I've had other blooms that sort of do that as they wilt.

Sorry for diverting a bit on your thread NYC.

Thank you Silken! Now I'm glad I bought the blue Den! Thank you for putting my mind at ease! And, sorry NYC for the digression!

All the blue orchids are not true blue except for the fake blue phal, which is real blue.
I think it's just marketing or people love to call them blue while in reality, they are all shades of violet although some look quite blue, but they will always have purple or violet hint in some degree.
Vandas are no exception. There are no "blue" vandas either. Online pictures are misleading sometimes and I find it very annoying because you buy plants based the color you are looking for.
We want realy color not photo enhanced color.

Anyways, your den is most likely Udom Blue and Genting Blue cross. There are small cute plant and I have one.
When they wilt, just as many dendrobiums do, they turn either light brown or pinkish, which eventually turn brown and fall off.

Silken- If you have grown dendrobiums in your settup for years, then I guess it works for you. However, I find the temperature (especially the night temp) a bit too low. You can keep them indoor and dry for the winter.

I agree, blue is not blue in the flower world for the most part. And I love blue! I've grown in my greenhouse for years, but only created my little warm micro climate last year. I should clarify that temps are a good 5 or more degrees higher night and day in there. It's a small area and because it is partially enclosed, the warmth from the T5 adds to the temps in the day also. Hopefully it will work again this winter. I have a cat that eats orchids so keeping them in the house except when they are in bloom and often to their peril is not an option! Thanks for the tips on its name!

I once ran across a nice list blue flowers, but have no idea what they were.
I personally had some plants that had true blue color flowers with no hint of purple.
Two nice examples are hyacinth (I think it was delft blue is the variety name, it's pale, pastel blue) and blue daisy, this is kind of generic name. It has nice sky blue petals with bright golden center.

Regarding your dens, well, if you've grown them in your setting for a number of years and they have survived fine, then I guess it's fine for them.
The ones with more biggibum or round flower shape take cooler temperature better than skinny flowered plants as these are naturally growing at a latitude closer to the equator.
I think the key is keeping them dry when the temp is low, like under 60F is very low for them I think.

You changed your main photo from pink miltoniopsis to this cattleya. started to buy some cattleyas now?

Thanks for the info on warm growing Dens. I don't have many of them or much experience with them yet.

I actually have quite a few cattleyas but many of them were seedlings. I have been getting some nice blooms lately. Quite a few more sheaths but they may or may not produce blooms. Too soon to tell. I thought it was time for an avatar change

Wow, you really have a green thumb with your dendrobium orchids. I fell in love with the Yamamoto Den. Nobile hybrids earlier this year. I have followed watering a lot during the heat and fertilizing with an orchid bloom booster fertilizer - stopped at the beginning of September. It wasn't until then that all of my canes seemed to finally have plumped up which seems strange due to the watering I gave them over the Summer. I got a gorgeous Den. Red Emperor Prince in March and over the summer it's canes became desiccated and kind of saggy but they are fine now. I repotted after the flowers bloomed, I don't know if the shock from repotting caused the plant to suffer. It grew new canes and a lot of roots though and I am hoping for flowers next year. Do these bloom off of old canes as well?

[NYCorchidman]

Hi, good to hear from you. good to know that your plant is doing well.

Yeah, I love yamamoto dendrobiums, but I can no longer provide cool period for them, so I mostly got rid of them. I plant to buy them in spring just for house decor now. oh, well...

Dendrobiums adjust to repotting routine really well as long as the timing is right. just as many other orchids: when there is root activity.
No matter how much water you give them during growth period, the canes do not fatten up until toward the end of the growth cycle. that is why you are seeing them plump up now.
For nobiles, they do not flower off the previously bloomed canes. Sometimes the old canes might produce very few off the availble nodes, but we're talking about the main flower show here.
They bloom off new, unbloomed canes.
So the more new canes the plant grows, the more spectacular blooms you can expect the following spring.

By the way, these tropical dendrobiums are great replacement for the nobiles for me. The only downside is that they don't take full sun as nobiles do, so I have to be careful. extra care, higher maintenance. lol

the gentain family i think has some very blue flowers if not almost true blue. look up gentiana verna. theres a weed that grows in my yard thats also very blue and fading to periwinkle (comellina communis). i find the indigoes in lobelias and delphiniums very desireable and a vanda in indigo would seems better to me than blue. plus i like the way blue orchids look next to the other colours especially primaries. they seem to light up
