Another bulb rots on Oncostele Pacific Perspective

Rotten pseudobulb on oncidium (right)

     My Oncostele Pacific Perspective lost another pseudobulb yesterday.  Although it still had green leaves attached, the bulb had turned mushy and had to be excised. This is the second pseudobulb to rot since it rotted its last one in May.  I am not sure what's causing this rot.  Generally orchids rot when there is too much moisture that is not drying out.  But if anything, I haven't been watering enough; the leaves on the newest growths are wrinkled from dehydration.  

     My guess would be that these problems arise from the orchid not having enough roots.  With its many old pseudobulbs, the orchid would not fit into any pot small enough to be appropriate for its root size.  As a result, the media would be both too dry near the top where many of the new roots were growing, and permanently soggy elsewhere, leading to bulb rot.

     Once again diminished, the oncidium is now in a 4 inch clear plastic pot, with loosely packed oncidium potting media.  There is a good amount of new root growth, which will hopefully support the two new growths as they mature.

Name change: Wilsonara Pacific Perspective = Oncostele Pacific Perspective

Oncostele (Wilsonara) Pacific Perspective

     I was searching around on the International Orchid Register today, when I noticed that my oncidium intergenic has been reclassified into a new genus.  My wilsonara is now officially an oncostele. The change doesn't really mean much to me, but I generally try to stick with the most recent official classifications of my hybrids.

     I had the oncidium growing on a sunny bathroom windowsill over the summer, and the bright light resulted in quite a bit of leaf damage on this oncidium.  I'm switching this orchid's placement with my cymbidium, which should be better able to to handle the hours of direct sunlight on the windowsill.  The oncostele is going to my orchid shelves to grow under the lights, and I'm putting the Cym. (Gordon Gibbs x Billion Dollar Baby) on the windowsill instead.

A cat called trouble

     Last night I awoke to a loud crash sometime around 5am.  The cat, in the midst of his usual daybreak energy rush, had jumped up on the bathroom windowsill and knocked both flower pots onto the floor.  My beautiful ceramic orchid pot was shattered, but the orchids themselves suffered no harm.

     The accidental uprooting gave me an opportunity to see the root progress on these two recovering plants.  My Wilsonara Pacific Perspective had a nice cluster of new roots, as well as a few longer older roots that were still healthy.  

     The noid oncidium, on the other hand, it still rootless.  How does an orchid that has been rootless for almost a year still manage to be alive and so leafy?

     I potted the two orchids back in their original plastic pots, and put them back on the same windowsill.  I know I am pretty much asking to get them knocked off again by not changing their location... but I don't really have any other place to put them at the moment.  The cat tipped the noid oncidium out of 

Edit (7/31): It took less than a day.  The cat tipped the noid out of it's pot again.  I've moved that pot to a less sunny, but hopefully more cat-safe window.  The wilsonara seems to be more secure in its original location, since it's in a heavier clay pot. I've moved it to the corner of the bathroom window, so that the cat can have room to jump on the windowsill without disturbing the orchid.

Mushy backbulb on Oncidium

The brown part of the backbulb feels hollow and mushy

     The oldest pseudobulb on my Wilsonara Pacific Perspective is rotting away.  The brownish portion of the pseudobulb (whose color the camera flash so nicely accentuates) is hollow and mushy on the inside.

    I don't want to repot the orchid now, since it's in full bloom, and I don't want to risk losing the flowers early.  The roots seem healthy, so I hope I am not making a big mistake by waiting.  But as soon as a blooms fade, I will be repotting, and cutting off the rotten bulb.  I will also be switching to a different potting medium, perhaps one specifically formulated for oncidiums.  Currently I have it potted in paph&phrag mix, because it's a fine-grade mix and the oncidium's roots are thin.  But the rot seems to indicate that it needs a change.

Wilsonara Pacific Perspective Time-Lapse

     Here is my first attempt at putting together a time-lapse of an orchid bloom.  It's far from perfect, but I am pleased with the results for a first attempt.  

     Lessons to be applied to future attempts will include staking up the flower spike to prevent it drifting across the field of view, and take better efforts to keep the background clear of clutter.  Also, it seems that even in the early days when the flower buds don't seem to be doing much in the way of growth... they are surprisingly mobile.  And when they do open, the final unfolding seems to take place over the course of only a few hours (and in the case of this wilsonara, very early in the morning while I'm still asleep).  For these pictures, I chose the less demanding frequency of taking photos once daily (increased to 3x per day when the buds were about to open).  I will try to increase the frequency of pictures for next time I try this.

In the meantime, here are some more photos of the Wilsonara Pacific Perspective in full bloom.

                                            

 

Noid no more: presenting the Wilsonara Pacific Perspective

     Within hours of me posting to the Identification subforum of the Orchid Board, a user 'WhiteRabbit' found a named match for my red oncidium.  My orchid, is very likely called Wilsonara Pacific Perspective.  The 'Wilsonara' genus is an intergenic of three orchid genera: cochlioda, odontoglossum, and oncidium.  While it is rare to be able to identify an intergenic orchid noid, the similarity between the blooms is so compelling, that I am convinced.  

Here are some more comparison pictures I made, joining my photos with similarly lit image search results:

So are you convinced?  I think I am. 

First blooms open on oncidium

A delicate veining of the petals shows through in the sunset light

     It's finally happened!  Almost exactly 2 months after I first noticed a spike, the first flower buds are opening.  It's a relatively small flower spike: only 6 blooms.  Once the orchid's roots have further recovered, I expect to see bloomings that match its former glory: flower spikes over 3 feet high with dozens and dozens of blooms.  For now, I am certainly enjoying my first orchid blooming since moving to New York!

     The flowers are about 2.5 inches across, in either direction.  They also have an odd sort of spicy/musky scent.  I can't quite decided whether I think it's pleasant or not.

how the color looks to the naked eye in diffuse light: a kind of terra-cotta earthy red

     

I edited the color tones in the above photograph to match how the orchid's color looks to my eyes, since my camera was making the reds of the petals and the yellows on the lip stand out much more than I could see. 

camera flash gives the blooms a lovely waxy red tinge, but looks nothing like what I see with my eyes

     All the three closeup shots of the blooms look very different due to changes in lighting.  One might think they were three different flowers!

two buds fully open, one partly open, and three flower buds still developing

     As you can see in the last picture, the inflorescence is not yet in full bloom.  I'll post an update once the last buds open.  In the meantime, I'm taking advantage of my tripod to put together some timelapse videos of the opening flowers.  It won't be the professional level, since I can't sit at home taking a photo every 30 minutes for a month as the flowers open (nor do I have the setup for an automatic shutter), but it's still pretty cool ;-).  

     If anyone seeing this has suggestions for what might be the name of this lovely noid, I'd love to hear any ideas!

New growths abound

new growth on blooming oncidium

     It seems that my orchids have picked up on the spring season, and responded with an abundance of new growth.  Above, is a tiny new growth on my currently budding oncidium noid.  Meanwhile, many other orchids are throwing out new leaves and pseudobulbs galore.

New leaf on phal: with 5 new healthy roots, I'm hoping this leaf won't end up stunted like the last 3 did

Oncidium flower spike--One week of growth

A sequence of growth

     I estimate that the spike had been growing for 1 week hidden within the folds of the leaves before I first noticed it.  Based on that count, the picture above shows growth from days 7, 11, and 13.  The spike quickly acquired a dark burgundy color, which matches the color of this orchid's blooms.  On day 12, I carefully pried the tip of the spike out of the leaf fold, and overnight, the spike straitened out to what you can see in the rightmost picture.

Oncidium flower spike!

 
     I was so excited to spot this last night.  This is not an orchid I expected to see blooming any time soon (its roots were in pretty bad shape). I am really hopeful that the flower spike takes, as it is probably my favorite among my plants. It aborted a flower spike last year due to poor potting conditions, so here's hoping that this time I'll do better.
     I'm not sure what triggered it--perhaps the apartment has been a little colder, or that I changed my watering style to be more conservative.  Now that the spike is there, I will be watering the oncidium with a low nitrogen bloom booster fertilizer, but otherwise trying to keep the conditions as stable as possible.
     One interesting note is that this spike showed up really suddenly.   Just a couple days ago I was looking at the wrinkling on the little leaf with concern (a sign of dehydration/root issues) and there was no sign of the spike.  I'll be keeping close tabs as the spike grows and develops over the next several weeks.


yay! :-)


Edit 3/28: Now blooming!

Oncidium NOID: a set-back

poor root health

     While watering my orchids the other day, I accidentally jostled my old oncidium NOID, and the plant fell completely out of its pot.  This exposed the rather pitiful current state of its roots, which is quite worse than what I had hoped.  Aside from the one longish root at the upper left of the picture, the plant's only living roots are the new growing tips.  Although the oncidium has been sprouting roots continuously for the last 2 months, they haven't been surviving.  I trimmed back a few rotten dead roots (long root on bottom right).

     The lack of roots and the ease with which the orchid tipped out of its pot both indicate that I had originally placed it in way too large of a pot.  To correct the situation, I searched for the shallowest pot I owned that would still be wide enough at the top to fit the oncidium's pseudobulbs.  The smaller new pot allows the plant to be more stable, and the smaller volume of media will be able to dry out faster.  Both of these changes should help improve the orchid's root health

comparison: oncidium in new, much smaller pot

     Since the pseudobulbs still have much more thickness than the ones on the oncidium 'the rescue' NOID I am not at this point worried about losing this orchid.  However I am disappointed that my 'NOID isn't farther along in its recovery.  I really hope the smaller pot helps, but the timeline before I can hope to see my favorite old orchid bloom again seems even longer now.

Oncidium NOID: the faded glory

     This oncidium NOID is the only other orchid to have survived the move with me.  I picked up the plant 2 years ago at a farmer's market with a 3 foot tall spike resplendent in burgundy blooms.  A plant so large was a sure bet to rebloom for me year after year, I thought.  If I knew then what I know now, I would have seen the signs of trouble.  Within two weeks, it dropped most of its flowers, and has sulked since.

wrinkled pseudobulbs are a sign of trouble

     Two years later, after some reading on proper oncidium care, I finally got suspicious about the state of the plant.  The pseudobulbs on this plant are all strongly wrinkled, which is a sign of dehydration.  While it is natural for old pseudobulbs to wrinkle slightly over time, the newest growth (top right of picture) should be plump.  The wrinkled state of these pbulbs are a clear sign of root trouble.  Another red flag is that the newest pseudobulb is only half the size of the two older ones.  If an orchid is healthy and growing, then new growths should never be smaller.  In the very top picture of this post, you can also see wrinkling on the two leaves at the front.  The wrinkling indicates that the orchid was not getting enough water at the time when those leaves were forming.


     When I finally got around to repotting the plant, the plant fell out of its oversized 8-inch pot... with the roots contained within the shape of a smaller 5" diameter mass.  The rest of the outside pot was filled with badly decayed wood shavings, and contained no roots at all.  Meanwhile in the heart of the root mass I found a smaller 2.5" plastic pot buried around the oldest growth.  This plant has not been properly repotted since it's very first deflasking!


    Lesson learned: always repot an orchid when you first get it.  You never know the true health of a plant until you see the state of its roots, and even reputable seeming vendors can sell orchids which are in bad need of repotting.


After I finished cutting away the old plastic from the root mass, the plant was left with very few healthy roots.  Within weeks of the repotting however, the young growths sprouted a veritable pincushion of new root tips.

A few weeks after re-potting: you can almost hear its sigh of relief

The roots today

Even a couple months after the initial repotting, the plant continues putting out roots.  Some of the initial roots have failed, while others seem to have established themselves (the white roots on the left).  Meanwhile, the leaves on the new growth have since doubled in size. 

I particularly like the purple tinge on the new growths

 I am a little concerned by the black spots on the top of the new leaves though.  I'm not sure what caused this damage, but at least it hasn't progressed since first appearing.

water damage or lampburn?

The plant still has a ways to go before it fully recovers.  Oncidiums bloom from new pseudobulbs, and since the newest pbulb has already aborted an attempt at blooming, I will likely have to wait for a new pseudobulb to grow before I can hope for a flower spike. I guess I will have to be patient before I can hope to see those gorgeous blooms again.
