Substantive vs Superficial Selection

When it comes to selection...there seems to be only two categories to choose from...artificial or natural.  But what about when we select for traits that help organisms adapt to nature?  Would we say it's natural selection that's human assisted?  Or artificial selection that's nature assisted?

My comment on Uncommonly early blooming Laelia anceps

*************************************************

The first L. anceps to cross the finish line? What did this guy do for the rest of the year? Cheer on the slow pokes?

The "volunteer" L. anceps on my tree started to put out a second growth back in August...





Here's a recent photo...





Given that temps have cooled considerably...and I've reduced water accordingly...not sure how completely the new growth will mature.

My L. anceps was too young to allocate any energy to flowering...but it sure seems theoretically possible to select for a L. anceps that blooms twice a year. The trick would be to cross-pollinate the earliest blooming individuals...which are the fastest and/or the coolest growing individuals. In some cases though they might simply be the luckiest individuals...ie in the warmest and/or most nutritious micro-climates.

But I think it's definitely a good idea if we all feature our orchids that finish the "race" (complete their growth cycle) in record time. Not just with L. anceps but with all epiphytic orchids. For example, this NOID ugly duckling...





...is one of my "fastest" Cattleya alliance orchids. I divided it this year which is why it finished later than usual. Noting which of our orchids are the "fastest" is basically highlighting the individuals that are better adapted to growing outdoors in Southern California. If we all exchange their pollen then we should be able to make much better progress in this area.

Salvation Army For Plants?

Comment on PATSP blog entry... Anthurium News: The Bad News

************************************************

I agree with Paul regarding the media...but not so much with regards to the composting. A while back I purchased a cheap NOID out of bloom orchid. When it bloomed for the first time I was rather disappointed with the flowers. You can see a pic of the flowers here. But I kept it around anyways. After a while I realized that it's one of the first of my gazillion orchids to complete its growth cycle. Basically, it suffers from a shortage of style but it's blessed with an abundance of substance. Now it's got a fat seed pod on it filled with around a million seeds. Eventually I might have a large variety of epiphytic orchids that grow all year long outdoors here in Southern California.

Even if some of your Anthuriums are short on both style and substance...it doesn't necessarily mean that they will be short on substance in other people's conditions. Plus, style is certainly subjective. So if the opportunity cost of keeping them around is too high...then I'd recommend just giving them away. I'd be happy to take some off your hands for the cost of postage. Or I could trade you some orchid seeds. :)

For a while now I've wondered about the viability of a Salvation Army just for plants. What do you think? Could it would work? Would you be willing to drop off a couple flats of Anthurium seedlings for a small tax deduction?

Tropical Texas Orchid Reserve

Reply to thread... Tampa Florida outdoor growing

*************************************************

CA2FLxplant, you don't miss Van Nuys?  hehe.  How much better could central Florida really be?

Actually I sometimes dream about moving to the Southernmost part of Texas.  It's almost tropical there.  I'd like to buy a bunch of acres and start an orchid reserve dedicated to the conservation and proliferation of CAM epiphytic orchids.  I'd attach a gazillion orchids to the trees and let nature select for the most drought/temperature tolerant individuals.  The goal would be to try and move the fittest individuals across the country via reasonably sized "steps".  

Here in California it's too big of a leap for epiphytic orchids to naturalize.   All epiphytic orchids are summer growers... but here they'd have to adapt to being winter growers.  Plus, it's a numbers game...the more seeds you throw at nature the more progress can be made.  And I just don't have enough trees here to throw seeds at. It's not like I can walk around the neighborhood sowing orchid seeds on street trees.  Well...I could...but then I'd probably have to explain to people why I was watering their trees.

Florida could work pretty well but Texas is nice because it's centrally located.  Plus, ideally, there would be a satellite location a few hours drive across the border into Mexico.  This would help function as "insurance".  Kind of like an external hard drive to back up important files (orchids).  If the main computer (Texas reserve) crashed (500 year freeze) then the most important files (orchids) could be easily restored.    

Eventually every botanical garden in the US would have orchids growing on their trees!  I think there's a chance that it might happen anyways...but I'd prefer if it happened sooner rather than later.

I didn't buy those flasks!  Did you?  Unfortunately the same flask is available again for the same way too reasonable price!

Please let me know if you decide to cross everything with E. tampensis and sow the seeds on every tree.  I'd love to hear all about it.  I'm really curious how readily the seeds of E. tampensis (both the species and its hybrids) germinate on trees in Florida.  If they don't readily germinate...then it's either because the precipitation/temperature wasn't adequate...or the necessary fungus wasn't present.  The absence of the necessary fungus would definitely be a problem.  The solution would be to try and proliferate the fungus by attaching inoculated orchids to trees.  I'm under the impression that orchid roots help the fungus colonize a tree.  The more a fungus has colonized a tree...the more likely it is that the spores will land on adjacent trees.  I have no idea how many orchids would have to be attached to trees in order for the virtuous cycle to be "jump-started".  But you're probably on the right track when your neighbors mention that they have random orchids growing on their trees.

It's possible that other epiphytic plants besides orchids help to spread the necessary fungus.  At the end of August my friend brought back a piece of Pyrrosia piloselloides from either Thailand or Cambodia. She gave me a small division and I attached it to a section of old trellis wood covered in New Zealand Sphagnum. I stuck part of the mount at an angle in a pot filled with bark and topped with a layer of Sphagnum. So the fern is both potted and mounted. Kinda hedged my bets. I thoroughly watered the fern and then I sowed some monopodial orchid seeds all over the surface of both the pot and the mount. The seeds were from...

P. vandarum x V. tricolor
R. imschootiana x R. gigantea?

Lastly I stuck the pot/mount in a zip lock bag under lights in my garage. The bag isn't completely sealed.

The fern quickly started to grow and last week I spotted one fat protocorm right next to the fern. It was just starting to put out its first leaf...which now looks a little wide for a vandarum cross. But perhaps the tricolor leaf is dominant.

I'm guessing that the orchid seed germinated as the result of fungus from the fern root. Although, the fern is attached to a twig...so maybe that's where the fungus came from.  But I definitely wouldn't be surprised if some populations of Florida's most common epiphytic fern...Pleopeltis polypodioides...had the necessary fungus in their roots.  So it's entirely possible that attaching this fern to trees might also help spread the necessary fungus.

Can Epiphytes Help Reduce Climate Change?

Reply to comment on The last uninvaded frontier?

**********************************************

Derrick, the other day I tried to imagine how much carbon dioxide would be absorbed if every Phalaenopsis ended up on a tree rather than in the trash when it finished blooming.  Unfortunately, even if the interest was there...the commonly available Phalaenopsis hybrids can't grow outside in places like California.  On the other hand, pretty much every New Zealand epiphytic orchid can grow outdoors somewhere in California.  If the cold tolerance of mass produced orchids could be improved...and many of them ended up on trees...then perhaps climate change could be reduced.

Right now I have four seed pods developing on my Neofinetia falcata hybrid that's growing on my Ficus macrophylla bonsai.  The pollen came from two Phalaenopsis hybrids and one species.  I'm hoping that the cross will have the best of both worlds...large, colorful flowers and temperature tolerance.

New Zealand has two epiphytic monopodial orchids that I know of...

Drymoanthus adversus
Drymoanthus flavus

Are they more cold tolerant than Neofinetia falcata?  I don't know.  I don't know anybody outside of New Zealand that grows them...or any other native NZ orchid for that matter.  For all I know they could be the key to reducing climate change.

**********************************************

Anybody know approximately how many Phalaenopsis are produced each year?  In terms of carbon dioxide absorption...would it be the equivalent of say 1,000 acres of rainforest?

Phorobana Shows

My thread in the CactiGuide.com forum... Plant on Plant Action

**********************************************

Hi everybody!

I recently joined this forum to share a link in this awesome thread to some photos of orchids growing on cactus/succulents.  Since I'm here I figured that I might as well subject you to more of my plant on plant propaganda.

How many of you grow plants epiphytically?  I already know the answer...not enough of you!  Everybody should grow plants on other plants.  Perhaps the most accessible case I can make for doing so is that you'd increase the chances that visitors to your garden would take more photos.   In technical terms...it would improve the value to space ratio.  In simpler terms...visitors would have more reason to linger longer.  

For example....here are a couple galleries of accidentally epiphytic cacti...one and two.  As you can see there's lots of photos of cacti growing on other plants.  These accidental epiphytes improved the value to space ratio.  We know this is true because people lingered longer and took photos that they wouldn't otherwise have taken.  The value to space ratio would have been improved even more if those accidentally epiphytic cactus had orchids, bromeliads or Tillandsias growing on them.

Last week I attended a cactus and succulent show at the LA Arboretum.  Guess how many of the entries had epiphytes attached to them?  Not a single one.  A few weeks earlier I attended an orchid show at the Huntington.  Guess how many of the entries were growing on cactus/succulents?  Not a single one.

If I had to predict the future...I'd guess that the lines between plant shows will be blurred.  If people only had time to go to one show...they'd pick the one that gave them the most bang for their buck.  This will be the show that has epiphytes growing on potted plants.  Visitors would linger longer in front of each entry...admiring the epiphyte...or the phorophyte...or both.  And because each entry would have broader appeal...it's a given that more photos would be taken.  Each additional photo taken and shared online would help provide the show with more publicity.

The question is...will this future happen sooner or later?  Personally I hope that it happens sooner!  I expect great things to happen as a result of this cross-pollination.

Not quite sure what this "holistic" show would be called.  The best word that I've been able to come up with is "phorobana".  There's always room for improvement though so if there happen to be any wordsmiths out there feel free to throw some other suggestions out there.  One qualification is that new words should meet the google alert standard.  Basically you should be able to subscribe to a google alert for the word and not be inundated with irrelevant results.

So...does anybody have any questions?  Like...is Aloe ramosissima a suitable host for Angraecum aloifolium?  I don't know the answer...but I'd sure like to find out!  For the past couple years I've been growing several dozen miniature epiphytes on a Crassula Gollum. The Crassula has excellent drainage so I can water the epiphytes with decent frequency.

If you're interested in learning more...here's my overview of growing plants epiphytically.

A Hasty Case For Naturalizing Epiphytes

Reply to thread... Video of Cattleya Blooming on my Tree

***************************************

Thanks! Regarding your honest questions...well...did you ever see the SNL skit with Christopher Walken where he needs more cowbell? I guess I'm the same way with orchids on trees. When I drive around Southern California I shout out the window..."all these trees need more orchids!"

As far back as I can remember I've always been a fan of more nature. When I was a kid my mom bought me the book "Vanishing Eden". It was filled with pages and pages of plants and animals that I really didn't want to vanish. Shortly afterwards I saw Bladerunner for the first time. I really loved the movie but I really didn't want the future to look like that.

Basically, when people attach orchids and other epiphytes to trees...they help to offset the loss of nature elsewhere. There's a lot of nature being lost elsewhere...so it's not just sufficient to add plants to the ground...it's necessary to add plants to trees. Doing so helps to create a virtuous cycle.

An orchid on a tree will help widely disperse far more necessary fungus than an orchid in a pot will. Here's how I've illustrated this...

When more fungus is dispersed to surrounding trees...this increases the chances that orchid seeds will germinate on them. So more orchids on trees will lead to more orchids on trees.

Orchids and other epiphytes on trees help facilitate cascades. As we all know too well...orchids are an excellent source of food for a wide variety of "pests". But adding an orchid to a tree doesn't just provide more food for aphids, mealy bugs, slugs and bush snails...it also provides more food for the spiders, lady bugs and lizards that eat these pests. Plus, an epiphyte on a tree can provide shelter and a home for all sorts of animals. Flowering epiphytes can also provide nectar to a wide variety of pollinators.

In addition to facilitating cascades...it's important to naturalize orchids because this helps to subject them to the process of natural selection. The more orchids that sidestep this selection process...the less orchids that will be able to survive in nature. The world is constantly changing...so if nature changes in one direction...but orchids change in another direction...then in the future we will only be able to see orchids in conservatories. We're not doing anybody any favors by overly protecting orchids from cold or drought.

The orchid family is so successful because they throw a lot of seeds at nature. If we want the orchid family to continue being so successful... then we have to help orchids throw more seeds at nature. If we help throw enough orchid seeds at nature...then it doesn't matter if future conditions are colder/hotter or wetter/drier...there will be plenty of orchids that have sufficiently suitable combinations of traits.

Perhaps it's somehow inevitable that the future will have plenty of trees with orchids growing on them. I don't think this is the case though. I regularly search flickr for orchid tree...and the rate of relevant additions is pretty low. So I do what I can to try and help encourage more people to think outside the pot.

What do you think? Do I need to be so persistent? Does your individual foresight show you a future with an abundance of orchids on trees? Will the world look like more like heaven...or...?

Do you wish you could grow orchids on trees too? You can! Just grab a houseplant and attach an orchid to it. Of course not all houseplants are equally suitable phorophytes. Which houseplants make the best phorophytes? I don't honestly know. But hopefully some of you brave experimenters will be willing to try and find out.
