According to Robert L. Dressler, monopodial is defined as "a growth habit in which the stem may continue to grow indefinitely, as opposed to sympodial".

The following is a list of 75 monopodial orchid species that are being grown outdoors year around here in Southern California. This list was compiled from a survey of 8 orchid growers: Don Brown in Santa Barbara, Butch (Rowland Collection) in Garden Grove, Christopher Croom in San Diego, Roberta Fox in Costa Mesa, Doug Overstreet in Glendale, Albert Owen in Encinitas, John Snyder in San Diego and myself in Glendale.

For brevity’s sake, no culture information has been noted but a simple rating system is used: 5 (thriving) to 1 (surviving) and “?” (too early to tell). If you have any culture questions regarding any of these orchids or if you would like to add an orchid to this list then please feel free to reply to this thread.

For more information on outdoor orchids be sure to attend the presentation that Doug Overstreet will be giving on the subject at the Southland Orchid Show on October 18.

Great to see this list! I recently purchased an Ascocentrum miniatum in hopes of giving it a shot, and it gives me hope seeing that someone has already tried it. I live in Encinitas, CA. I have experience with some of the same monopodial species, and some that aren't on the list:
Aerangis verdickii 5
Amesiella monticola 4
Angraecum didieri 4
Angraecum sesquipedale 4
Cleisostoma birmanicum 5
Holcoglossum amesianum 5

How many folks have tried any Renantheras? I believe that Renanthera imschootiana should do fine outside year round in SoCal. Any others?
Has anyone tried Rhyncostylis coelestis? I think that it may come from high enough elevation.

Thanks for sharing your list! Great to see some new additions and additional supporting evidence for previously listed species.

Renanthera imschootiana has been on my want list for a while...only saw it for sale a couple times...but never at a price I was willing to rationalize paying. Hmmm...speaking of which...I think Alfred might have picked one up a year or so ago with a small off-shoot that he said I could have when it was large enough...??

A little less than 2 years ago I picked up Renanthera Scarlet Yuka at a show and it's been blooming and growing with respectable consistency. I'd give it a 4.

Vanda coerulea 5- Studio City
Mine has been in bloom since February!

Yes Carlos, I believe that I bought that Renanthera imschootiana that you passed up at the SB show a couple of years ago. Blooming right now and what a beauty. Unfortunately no off-shoots...neither does my other one that I got from Norman's Orchids.....will keep you in mind should one be produced.

Was talking with Harry Phillips this past weekend at the Santa Barbara Orchid Fair and was very surprised to find out that he has been growing Phalaenopsis aphrodite outside year around on his Ficus tree. He said it is the variety from Taiwan and not from the Philippines.

For those that haven't seen it is a photo of Vanilla chamissonis growing outdoors in Los Angeles...

thank you for posting this list. it has been very helpful. i wish there was a similar listing for sympodials. it has been a challenge to find information on growing orchids outdoors in socal. we really can grow a lot of things outside, with a little protection from the sun. a lot of hybrids from these species also can also live outdoors, with some trial and error i have a bunch of outdoor orchids. although my vanda coerulea is doing just terrible! the tips of the leaves seem to be burning off. not sure what the problem is, maybe the LA tap water? but others are doing just fine. a great hybrid that grows and flowers all year long is Vanda Paki. a hybrid of suavis and cristata. i have a nice Renanthera Imschootiana. it is doing very well, in a plastic basket with no medium. i also have a few small renanthera Tom Thumb hybrids that have taken the winter well, even as seedlings. any mini vanda with Neofinetia will do well outside, i have a few mini Ascofinetias and Vandafinetias that are doing great.
