Show and Tell


From Kurt Shanebeck:


Outdoors coastal, north of Los Angeles:

A challenging month for my orchids. The heat wave we had a few weeks ago was tough on some of my plants (temperature hit 110) especially the masdevallias (not surprising), and some plants in bud had damaged flowers. Here are some of the blooms that came through okay. All grown outdoors.

Aerangis mystacidii

Native to Southern Africa at elevations to 1800m. Growing mounted and shady.

Arpophyllum alpinum

(Kew has this as a variety of giganteum) Grows potted in bark with bright light.

Cattleya bicolor

Growing in a medium bark mix with bright light

Cattleya (Laelia) colnagoi

A rupiculous laelia from Brazil. Growing potted in bark/granite mix with bright light.

Dendrobium subclausum

Growing in sphagnum moss in a basket under moderately bright light. Kept moist.

Prosthechea (Encyclia) radiata

Native to Mexico. Very fragrant long lasting blooms and a vigorous grower. Growing potted with bright light.

Prosthechea rhynchophora (syn. Encyclia)

Grown mounted with moderately bright light.

Gomesa radicans (syn. Ornithophora)

Native to Brazil. Lush grass-like foliage produces many tiny (1/4”) flowers. Grows potted under moderate light.

Miltonia clowesii

Native to Brazil. Growing potted under bright light.

Oncidium leucochilum

Native to Mexico and Central America at elevations up to 2000m. Growing mounted with moderately bright light.

Miltonia regnellii

Native to Brazil. Growing potted with bright light.

Rhynchostele bictoniense (syn Lemboglossum)

Native to Mexico. Upright spikes. Growing potted with moderately bright light.

Vanda testacea

Growing mounted with bright light.

Vanda falcata (syn. Neofinetia)

Growing mounted under bright light.



From Ed Lyszczek:


Coastal, California Central Coast

Guarianthe (Cattleya) bowringiana

Here are standard Cat. bowringiana and a coruela form ‘Blue Angel’. Both grow very well in my greenhouse which gets into the low 40’s on winter nights and in the high 90’s during hot summer afternoons. Watered daily in summer and fertilized at half strength every one to two weeks, Spring through Autumn.

Stanhopea oculata

it grows in my intermediate greenhouse (very overgrown at the moment with way too many orchids) in a wire basked lined with sphagnum moss and filled with coarse bark. The scent of this Stanhopea is mint-like and I think it smells exactly like mint chocolate chip ice cream.


From Chris Ehrler:


Coastal, California Central Coast

Dendrochilum magnum

Grows in the Philippines as a cool growing epiphyte at elevations of 1600 to 2000 meters. Grown in a cool greenhouse in a plastic container filled with a bark and lava rock mixture.

Dracula ripleyana

A cool growing epiphyte that is thought to be native to Costa Rica. Grown in a plastic mesh pot filled with sphagnum moss in a cool greenhouse.

Dracula moreleyi

A cool grower that grows natively in northwestern Ecuador in wet forests at an elevation of about 1900 meters. Is this a face only a mother could love? Grown in a plastic mesh pot filled with sphagnum moss in a cool greenhouse.

Pleurothallis allenii

Grows in central Panama as a warm to cool epiphyte at elevations between 550 and 1000 meters. This plant is in a cool greenhouse mounted to a piece of wood with a small amount of sphagnum moss on the roots.

Epidendrum porpax

A hot to cool growing, mat forming epiphyte found in Mexico, Guatemala, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Venezuela, Ecuador, Peru, Bolivia and Brazil in wet montane and cloud forests at elevations of 400 to 1800 meter. This orchid is currently growing on a piece of wood with some sphagnum moss at the root. This orchid is growing well on a piece of manzanita that is suspended vertically but I plan to switch it to a larger and wider piece of redwood and orient it horizontally to see how it grows better in a different orientation.

Pleurothallis bothos

A warm to cool growing epiphyte found in Costa Rica at elevations around 750 to 2400 meters. This plant is growing in a clay pot filled with sphagnum moss which is placed in a cool greenhouse.

Pleurothallis ruberrima

Found in elevations of 750 to 2800 meters in Colombia, Ecuador, Peru, Bolivia and Venezuela in wet montane forests as a warm to cold growing terrestrial or epiphytic species Currently growing in a cool greenhouse in a sphagnum moss filled clay pot.


From Scott McGregor:

All orchids grown outdoors, coastal southern California

Arundina graminifolia

Rumored to require warm to hot conditions, this bamboo-like terrestrial thrives outdoors here in full sun.  Acquired as a $5 plant in a plastic bag at the Kona (Hawaii) airport, it has turned into a “bush” about 4’ tall and 3’ in diameter.  Flowers are produced at successively at the end of each mature cane. 

There is a short, 12-16” varietal (revoluta) of this species that I recently de-flasked.  Looking forward to those seedlings blooming in the next few years!

Cattleya (Laelia) dayana v. major

Another nice mini Brazilian Cattleya species.

Cattleya (Laelia) pumila 'Dark Diamond'

A nice variety of this mini species.

Cattleya (Sophronitis) pygmaea

The mini of the Sophronitis group, but pretty and worth growing.

Ceratostylis retisquama (rubra)

Grows below 500 meters in the Philippines, but seems to be happy outdoors here.

Cleisocentron gokusingii



Angraecum magdelanae

A second flowering this summer on one of my favorite Angraecums.  This species stays compact, easily forms multiple growths, and the flowers have a wonderful clove-scent at night.

Dendrobium victoria-reginae

Blooms at various times during the year and prefers cool/moist conditions.  The violet flowers have blue overtones.

Dendrobium caliculimentum (dichaeoidies type 3)

An odd species from New Guinea, likes it cool and moist.

Cynorkis fastigiata

I had planned to harvest seeds from C. fastigiata (the weed orchid) to give to some people, but I was too slow as the pods ripened, opened and dispersed all their seeds over the two weeks I was away!  This orchid goes from flower to seed in about 6 weeks.  Hopefully some will germinate on the ground and I’ll collect them.


From Roberta Fox:


Outside in the Back Yard:

Acianthera hystrix ( Pleurothallis raduliglossa)

I don't know how much credit I can take on these, got the plant in March, definitely not in bloom. Flowers are about 5 mm (1/4 inch) long and maybe 2 mm wide. Teensy. Leaves about 2 cm (a bit under an inch). From Brazil, cool-growing.


Acianthera (Pleurothallis) strupifolia

Second time this year that it has bloomed. It comes from a range of elevations in Brazil, grows cool and shady.

Aerangis mystacidii

From a wide area of southeast Africa, it grows over a range of elevations. Grown shady and damp, but dries quickly. Lightly night-fragrant.

Ansellia africana var. nilotica

This one also blooms in the spring. A robust plant, which produces upward-pointing "birds nest" roots when it gets crowded in the pot.

Cattleya forbesii

Not the most impressive Cattleya, but it is nearly bulletproof. It's very cold-tolerant, and also blooms 2 or 3 times a year. It transmits both characteristics to its hybrids.

Catasetum osculatum

Like all of my Catasetinae, it spends much of the year outside, when nights are above 55 deg F. When it gets cooler and starts to go dormant, it'll move into the greenhouse where it will receive its dry winter rest.

Chondrorhyncha (Benzingia) reichenbachiana

From a range of elevations in Colombia, Panama, and Costa Rica. A really cute little flower.

Cleisocentron merrillianum

One of the truly BLUE orchids. Leaves are long and terete. Flowers look identical to Cleisocentron gokusingii (see Scott's section) but that species has shorter, semi-terete v-shaped leaves. Both come from high elevations in Borneo. This bloomed just before the heat hit, so color was very nice. It blooms several times a year, and has better color in cooler weather. This color is accurate, no manipulation.


Dracula woolwardii

This one bravely bloomed while the heat wave was unrelenting. Nights were fairly warm, but it still put on a good show in the morning over almost a week.

Miltonia candida

Grows over a range of 500 to 800 m in southern Brazil. This seems to suddenly be Miltonia season... several species blooming at the same time.

Cymbidium dayanum

This cultivar has variegated leaves. It is getting ready ot outgrow its pot again.

Encyclia alata

Native to Mexico and Central America. It probably would grow better a bit warmer, but it does grow and bloom. It is quite fragrant.

Gurarianthe (Cattleya) bowringiana

Last month I showed you the coerulea form. This is the typical form.


Cattleya (Laelia) colnagoi

One of the rupiculous Laelias from Brazil. It grows in mostly gravel with just a thin layer of potting soil.

Cattleya bicalhoi (Laelia dayana)

You saw Scott's... this one is mine. The flower is as big as the plant.


Miltonia moreliana 'Candella's Delight'
(Milt. spectabilis var. moreliana)

This is an awarded cultivar, probably tetraploid. It has a huge, flat lip.


Miltonia moreliana
(Milt. spectabilis var. moreliana)

This is the generic (likely 2n) version. More flowers, and very dark color. Maybe not as impressive by judging standards, but very nice in its own right. Leaves tend to be on the yellow side. It grows quite bright, for best blooming. This was for a long time considered a variety of Miltonia specabilis, but now is recognized as a separeate species.


Miltonia regnellii

Here are both the typical and aurea forms. The "tipo" flowers are a bit larger and flatter, but the color of the aurea form is (to my eyes) more interesting. So I enjoy growing both.

Miltonia spectabilis f. bicolor

Flowers reflex so form isn't great, but it's nice to have yet another color variety.


Polystachya subdiphylla

Most Polystacya species are warm growing, but this one comes from around 2000 m. in Tanzania, and grows cool and shady on my patio.

Prosthechea prismatocarpa

Native to Costa Rica and Panama, at elevations from 1200 to 1360 m.

Sobralia fimbriata

Small short-lived flowers, but fringes everywhere.

Sobralia sp.

Labeled Sobralia macra, but it isn't. Sob. macra can be fairly tall and rangy, while this one is not much over 2 ft. tall. Along with the "normal" growths (leaves, with flowers at the top of the growth) it has some shorter growths without leaves that can also produce flowers.

Stanhopea oculata

A couple of months ago I showed a species labeled "Stanhopea bucephalus" that is considered a form of Stan. oculata but had no spots. THIS one is the classic Stanhopea oculata, full of spots or "eyes", living up to its name. It has a light, pleasant fragrance.

Stanhopea wardii

This species has a heavy, almost musky fragrance. This plant has produced several inflorescences, that are blooming in sequence. Eah set of flowers lasts only a few days, but a multi-spike plant can be in bloom for several weeks. Another Stan. wardii also has mulitple spikes, and so I have another couple of weeks of enjoying the lovely fragrance and weird flowers.

Telipogon astroglossus

This is a micro-mini plant with half-inch flowers, and a wonderful fringed lip. It bloomed in May, and now I have another set of flowers, larger than the plant. Most Telipogon species come from high elevations and tend to not survive our summers. This comes from a lttle lower, and seems to do fine. It looks more like Trichoceros than the usual round Telipogon.

Zygopetalum maxillare

I'm not sure why, but these flowers always make me smile. It grows in a basket, in sphagnum.

In the greenhouse...

Cyrtorchis chailluana

From central and west Africa. It is night-fragrant.

Dendrobium venustum

It was the intricate, fringed lip that attracted me. It is native to a wide area of souteast Asia, at elevations from 300-600 m. It possibly could grow cooler, but is doing so well in the greenhouse that I'll just leave it there, it is small and doesn't take up much space. It is deciduous, but it doesn't get dried out in winter and seems to bloom well anywan.

Phalaenopsis tetraspis f. imperatrix

This species, like its close relative Phal. speciosa, can produce flowers with different combnations of white and red on each flower. This color form produces a large proportion of red flowers with just a bit of white on the tips of the segments, bu here I got one with a lot more white.
