From Arnold Markman:


Intermediate Greenhouse, coastal San Diego area

Daily watering unless otherwise noted.

Bulbophyllum wendlandium

Bulbophyllum thaiorum

Cymbidium tigrinum

Grown mounte. Watered every 2-3 days in winter, daily rest of the year,

Dendrobium falconeri

Not watered from mid-November to mid-February, but misted daily. (Ed.: Misting is watering...) Gets full watering after mid-February.

Dendrobium ceraula (gonzalesii)

A couple of the canes have nothing on them, they looked dead.  This plant sprouts flowers from the deadest looking canes 

Dendrobium harveyanum

I grew this plant following Marni Turkel’s advice to “neglect it” in the winter.  From mid November to mid February, it just got misted and never watered. (Ed.: So light watering.) It’s put on quite a nice show of blooms. Since mid February, I water it every day.  

Restrepia brachypus

Dendrobium stricklandium

Not heavilly watered from mid-November to mid-February, but misted daily. Gets full watering after mid-February.

Dendrobium unicum

Not heavilly watered from mid-November to mid-February, but misted daily. Gets full watering after mid-February.


Dracula villegasii

This grows in the cooler and windier east end of intermediate greenhouse.

Eria sp.
Probably Bryobium (Eria) hyacinthioides

Labeled Eria brachyata, which doesn't exist. If a misspelling of Eria brachiata, it doesn't look like it. Photos and the appearance of the plant (thin leaves that come to a point), are the best match to Bryobium (Eria) hyacinthoides. and from the front, look like little hyacinths. Watered 2-3 times a week.

Gongora scaphephorus

This bloomed in February (shown in March) and bloomed again in May.

Masdevallia erinacea

Masdevallia floribunda

One can see why it is named floribunda!

Schoenorchis juncifolia

Oncidium (Solendiopsis) tigroides


From Scott McGregor:

All orchids grown outdoors, coastal southern California

Angraecum arachnites

A clump of three Angracum flowers with spurs and sepals like tentacles.

Cattleya harpophylla

A reliable May bloomer with long-lasting and intensively saturated orange flowers.

Oncidium (Gomesa) concolor

Large, bright-yellow flowers from a small plant.  A delightful species.

Sobralia rupicola

A recent acquisition of a large plant so I can’t take credit for the flowers this year, but an awesome compact Sobralia species from Bolivia, growing up to 1900 meters.  The 3” flowers last a week or so (that’s long for a Sobralia) and have multiple buds on lateral nodes near the top, rather than sequentially flowering from the terminal node like most Sobralias.  The flowers remind me of S. callosa, as they are in the same subsection Abbreviatae.  I had previously purchased a seedling of this rare species from Andy Phillips a couple years ago and it is probably a year or two from blooming—open to sell/trade that one if anyone is interested.


Porroglossum meridionale

A happy Porroglossum just coming into bloom with small but cute flowers.  This species is one of the easier outdoor Porro’s.

Restrepia sanguinea

Blood-red Restrepia, with original tag.  They sure don’t make plastic tags like they used to—this one has bloom records back 34 years!

Sarcochilus hartmannii

A reliable and cheerful Spring bloomer


From Roberta Fox:

Coastal southern California

Outside in the Back Yard:

Brassia (Ada) glumacea

Not spectacular, but extremely fragrant, reminiscent of ripe peaches. Often, I smell it before I see it.

Angraecum germinyanum

The highest number of flowers that I have had open simultaneously. The plant is a rambler - only a small portion of it is still in the basket. Each growth produces one or two flowers at a time, so to get this lovely show, it had to mature with multiple growths. Well worth the real estate that it takes up!

Barbosella cucullata

This is a little flower machine. Because the buds are green like the foliage, they are not obvious until they burst into bloom. (Note the top of the plant tag in the background, for scale.) Native to Ecuador, Bolivia, Colombia, Peru and Venezuela, at elevations from 2500-2900 m.

Bifrenaria harrisoniae

Native to Brazil S and SE, elevation 200-800 m, growing on exposed cliffs in full sun. Fragrant, and I love that fuzzy lip.

Holcoglossum flavescens

Small flower on an even smaller plant. Native to southwest and south central China, elevation 1200-2000 m.


Guarianthe (Cattleya) aurantiaca

This species grows in Mexico and Central America at a range of elevations, 300-1100 m. Flowers have heavy, waxy substance. Clear orange is the most common color, then there are heavily-spotted ones, and also lemon-yellow.

Cattleya mossiae f. semi-alba

This is the national flower of Venezuela, growing at elevations from 900-1500 m. Locally know as "Flor de Mayo", for its bloom time. It is sweetly fragrant. The typical form is lavender. (I have one of those also, but the thrips got to it first, alas.)


Coelogyne nitida (Coelogyne ochracea)

Kew considers these to be synonyms. At the last meeting of the San Diego County Orchid Society Species Study Group, several people disagreed with the synonymy, considered it to be Coel. ochracea. Either way, it's native to the Himalaya region of northern India, China SW, and much of Southeast Asia, at elevations 1500-2300 m.

Coelogyne speciosa

Native to Java, Sumatra, Borneo at elevations 750-1800 m. produces several flowers sequentially on each inflorescence.

Cymbidium lowianum f. concolor

Cym. lowianum is very popular as a decorative plant in China and southeast Asia. This plant has been in my collection for a long time, has not bloomed for many years, and suddenly it did. This year has been weird, with some usually-reliable orchids blooming pooly or not all, and others puttiing on a much better-than-usual show. This one clearly liked what Mother Nature threw at it.

Dendrobium jenkinsii

This is closely related to Dendrobium lindleyi (aggregatum, aggrevatum...), a relatively miniature version. I have found it to be much more relable than its fussy bigger cousin. It doesn't get dried out in winter, and blooms anyway.

Dendrobium rindjaniense

Native to a very limited range of the Lesser Sunda Islands of Indonesia, at around 2000 m. The bumpy canes are fascinating. The bare, leafless canes can re-bloom over several years. As this plant has grown, it went from one little cluster of flowers, to two, and this year just exploded. It is in a 4-inch basket. Very compact, and completely charming.

Dendrobium scoriarum

Native to Yunnan, China. This one was a total surprise - last year, a bare cane growing from a cluster of bare canes of a completely different species, bloomed with these very distinctive flowers. After the bloom, I repotted it, was able to separate what was, of course, two plants, and potted it separately. The single bare cane is now producing several keikis, and I have high hopes for it.

Diuris drummondii

This is the last of my Mediterranean-climate terrestrials to bloom. The rest have already gone dormant. It is native to western Australia. It is relatively tall, so that it is visible above the grasses with which it grows.

Leptotes pohlitinocoi

Native to Brazil, as are my other Leptotes. IOSPE says it is warm-growing, don't tell MY plant! (It does fine in my back yard.)

Leptotes bicolor

The largest, and most commonly grown, of the Leptotes species. It easily produces specimen plants. Mine is mounted on a stick which is covered with roots. If it were on a flat mount, with more room to spread out, it likely would have a LOT more flowers. I include it anyway, for comparison with the other species.

Leptotes unicolor

This species comes in a range of colors, from white to pink to this dark pink. But, as the name implies, one color for any given plant.

Masdevallia coccinea

The best blooming of this plant that I have had so far. There are still two buds, so when the oldest flowers drop the show will go on for another month. It almost glows, and has a velvety textture. In years past I have had lots of problems with bugs causing bud blast. This year I escaped.

Maxillaria pumila (Maxillaria minuta)

Native to SE Brazil, 700-750 m. This is another one that IOSPE says is a warm-grower. but it does fine in my back yard so clearly has cold-tolerance.

Pleurothallis viduata

This is in bloom about 10 months of the year, but in spring it produces its most dense bloom, so now is the time to show it. It produces new flowers sequentially from each growth. I don't trim the old flower stems until the winter when it pretty much stops blooming, since it is very difficult to tell the old ones from the emerging ones. Once a year it gets a haircut.

Polystachya pubescens

For a long time I thought this needed to be warm. But last year I moved it out of the greenhouse, and it has done better than ever. Native to South Africa.

Renanthera imschootiana

Plant is only about 4 inches, but this is the second year it has bloomed. It can get much larger. Native to north India, and southest Asia, elevations 1000-1500 m.

Renanthera pulchella

Very little information about this one - IOSPE says it is a hot-growing species from Myanmar, but gives no elevation data. The plant is about 8-9 inches, with 2 inch flowers. I have had it for about 7 years, it blooms every year - and clearly does not mind the cold.


Sobralia macra (or maybe not)

The taxonomy of the Central American Sobralias is very messy. I did find an article on the subject. This may be Sob. macra, or maybe Sob. aspera. The one that Scott and I have that is much smaller, with different flowering habit labled "macra" but not, may be Sob. pendula. Probably, this should just be called Sobralia sp.

Stanhopea tigrina var. nigroviolacea f. albescens

This species is normally noted for its large, darkly-colored flowers. Here is the albescens form - not alba, it has some faint red pigment (pink, actually), but is very pale, almost ghostly. The photo above was taken just as it was opening. Then, the petals eventually wrap around the sepals. Below, I show the typical form just for reference. Those won't bloom until somewhere around the middle of July, spikes barely starting to be visible.

Epidendrum lacustre 'Wow Fireworks' AM/AOS

This is the purple Panama form of the species (the typical form is green and white). Culture is full sun, sopping wet. I hang it up with the L. anceps - anything less than toasing sun and the colors are not as intense. To keep it wet enough in that bright location, it's potted with a big lump of sphagnum in the middle, just filled in with bark. It is extremely vigorous, periodically gets split into two 2-gallon pots so that I can lift the "beast".


Cattleya (Laelia) sincorana

Great flower-to-plant ratio. Flower is 3 inches on a 2.5 inch spike. Leaves are around 1.5 inch, pseudobulb about an in inch. Native to Brazil, elevation 1200-1500 m.

Maxillaria scalariformis

Soft pink flowers contrast with the dark green leaves. These grow well outside at Andy's Orchids. My climate is very similar but somehow, not quite the same - I have lost several during the winter chill. These need to stay wet, but I ended up with crown rot. (Dry would kill for sure, however) Now, I move it to the greenhouse just for the coldest months of winter, and it has done very well. It blooms in the fall (just before it's time to move it inside) and in the spring, after it has been out for a month or so. It is native to Panama, elevations 1000-1300 m. A very few degrees of temperature difference in winter, or perhaps the presence of a wall radiating heat, may make the difference between success and failure. I do seem to have found the formula that works for me.


Arpophyllum giganteum

Native to southern Mexico, through Central America to Venezuela. It lives over a wide range of elevations, from 350 m to 2100 m. That would indicate that it could be grown just about anywhere - warm, cool, or whatever. It's growing in a basket wtih very little medium, a very forgiving plant.

In the greenhouse...

Dendrobium taylorii (Cadetia taylori)

Half inch flowers with fuzzy lip. Native to northeastern Queensland, Australia.

Polystachya campyloglossa

Native to central Africa, elevation 1100-1800 m. Based on the elevation, probably could grow outside.

Phalaenopsis modesta

From Borneo


Gongora scaphephorus

Native to Colombia, Ecuador, Peru. Bolivia at elevations 600-1100 m. Just a little too warm-growing to be happy outside at my house, I think. From the elevation range, I'd expect a minimum temperature of around 50 deg F would be appropriate. Otherworldly-appearing flowers.
