Maxillaria rodrigueziana

Maxillaria rodrigueziana - Flower photo by Richard LindbergI took the plant picture just after I got it from Andy's Orchids at POE two years ago. I was going to do an updated picture, but it would be too embarrassing to let you see what I have done to this poor plant. And yet it is blooming.

Maxillaria rodrigueziana - Plant photo by Richard LindbergMaxillaria rodrigueziana grows Costa Rica and Panama in cloud forests at low elevations. It is hot growing, fragrant and blooms fall and spring.

I am about ready to give up on the whole Maxillaria grandiflora complex. They don't seem worth the space and their requirements conflict with my Cattleya and Laelia plants. The grow huge and the flowers don't last long.

Epidendrum coriifolium

Epidendrum coriifolium - Flower photo by Richard LindbergI enjoy green flowers but don't get plants just because of that. However, this is a "must have" for a green-flower collector.

Epidendrum coriifolium grows from Mexico through Central America to northern South America in low altitude and wet mountain forests. It is warm to hot growing, fragrant and needs bright light.

From that description it sounds hard to grow, but it is not, at least in a bright greenhouse. This piece is a backbulb from a division made less than a year ago. It has started its second new growth.

Dendrobium parishii hybrid '#1'

Dendrobium parishii hybrid '#1'When this plant bloomed this week my mind went immediately to Dendrobium parishii. The plant is generally the right shape and there is a Dendrobium parishii in the collection. There will often be duplicates in a collection that is a few years old.

Dendrobium parishii hybrid '#1' - Plant photo by Richard LindbergThis plant has a tag that had been written in ball point. Part of my job in maintaining the collection is to catalog it. I do the best I can, but identifying orchids can be tough when the writing on the tag has completely faded away.

This plant is not Dendrobium parishii which blooms on old canes in the spring after a dry winter rest period. This has the general shape and color, but the lip is entirely different. I will only go so far as to say that one of the parents is Den parishii.

There is new growth just starting so I will repot and stake up the plant. I will add some rock to the mix to decrease the water holding capacity of the medium. I can't tell without looking at the roots, but the pot looks a bit large. Next year the blooming will be better.

Cymbidium dayanum

Last spring I divided a specimen Cymbidium dayanum. Dividing a large plant almost always produces backbulbs.Cymbidium dayanum backbulb in early August - rootless and fragile I took two individual rootless backbulbs and potted them together tied to a bamboo skewer to hold them steady in the pot.

At the beginning of August I checked the divisions. Both of these pseudobulbs had long since lost their leaves and I decided that they were dead. I pulled them out of the pot. I was very surprised to see new growth on both of them. Mouse over the picture on the right.

Cymbidium dayanum as it is right now - still two years from bloomingI repotted them individually as gently as I could. New growths are VERY easy to break off.

I was very lucky. Both of the pots have grown. I have even added this plant to the inventory. It has a long way to go but it has a good chance now.

Pleurothallis palliolata

Pleurothallis palliolata - Flower photo by Richard LindbergI love my greenhouse. I can grow a wide variety of orchids that I could not have grown indoors. I went through a phase where I thought that I could grow anything and everything.

Pleurothallis palliolata grows in Costa Rica and Panama. Cool to warm growing and needs low light compared to many of the other plants I have.Pleurothallis palliolata - Plant photo by Richard Lindberg Still, it did quite well through the summer when the greenhouse was warm and wet.

Winter is another story. With the heater on the humidity was much lower and the watering was less frequent. Most of my collection was fine with that. None of the Pleurothallidinae do well. I have lost some plants already this winter.

I have moved all of them to Sonoma. All the watering there is by hand and there is more room to separate watering zones.

They can't stay in Sonoma forever. I will need to re-evaluate the range of plants in the collection. I may need to sell these off so that a year from now I am not trying to juggle so many requirements.

Don't try this at home.

Laelia anceps 'Mendenhall' AM/AOS - Flower photo by Richard LindbergLaelia anceps 'Mendenhall' AM/AOS - Plant photo by Richard LindbergThis is a one pseudobulb division from my Laelia anceps 'Mendenhall' AM/AOS. The rest of the plant was made into backbulb divisions. They were all potted in tightly packed sphagnum moss in plastic pots and put in very bright and warm conditions.

Laelia anceps grows well and blooms well in cultivation. It grows in Mexico and Honduras. It is warm to hot growing and needs a dry winter rest and bright light. If it is dry it can winter outside if there is no hard freeze.

I have perhaps 100 backbulbs and small divisions of several Laelia anceps varieties. When this plant put up a spike I should have cut it off. Blooming takes quite a lot of energy.

Epidendrum laterale 'Emerald Garden' CBR/AOS

Epidendrum laterale 'Emerald Garden' CBR/AOS - Flower photo by Richard LindbergEpidendrum laterale 'Emerald Garden' CBR/AOS - Plant photo by Richard LindbergI have had this plant for three or four years but I did not add it to the inventory until about a year ago. It had a tag that was hard to read, and I only figured it out by taking an opportunity to talk to the person who gave it to me.

Epidendrum laterale grows in Costa Rica and Panama and into Colombia. It grows very tropical in humid, warm to hot conditions at low elevations. It is fragrant and the flowers are reasonably long lasting.

This plant needs to be on a larger mount. I had to place it as high as that because of the roots at the time. It has grown well and has not climbed much. It will not outgrow the mount for quite awhile. I just am not pleased with the overall visual effect.

Restrepia trichoglossa

Restrepia trichoglossa - Plant photo by Richard LindbergThis Restrepia trichoglossa was a gift from a friend who is downsizing her orchid collection. It is in pretty good health with some minor slug damage. I will probably repot and divide it in the spring.

Restrepia trichoglossa - Flower photo by Richard LindbergThe genus Restrepia (Rstp) contains 30 or 40 species found from Mexico to Northern Argentina. Their culture is similar to small Pleurothallis species and grow well with small pots, high humidity and shady conditions.

Restrepia trichoglossa grows in Panama and northern South America in a wide altitude range where there is a wet and cool cloud forest. It blooms successively in summer and fall.

Schomburgkia tibicinis rescue

Schomburgkia tibicinis - Plant photo by Richard LindbergOne of the plants that the rat knocked over was this Schomburgkia tibicinis. Not the pot but the plant in the pot. It was not hard since there were no roots.

The way I read this plant, some time in the spring or summer of last year this plant had been removed from its pot and dead roots trimmed. There was little to hold it in the pot when it was replaced, so a wire had been used to hold it in place.

The plant was put back in a bark mix. The plant has been trying to grow new roots and the last two growths are in pretty good condition. Still, going into the winter with so few roots in a pot of wet bark would have been a challenge for it. It was lucky that the rat tipped it over.

I am going to treat this plant as if it were a total rescue. That is not far from the truth.

This has seven pseudobulbs and it has filled the pot. To my eye there are three divisions here. The newest three pseudobulbs is one. The remaining four can be divided two and two. All three go into rock pieces.

Schomburgkia tibicinis grows from Mexico through northern South America. It is warm to hot growing, wants full sun and is fragrant. The plant is big and the spike can be as much as 15 feet long. The genus name has been changed to Myrmecophila in the naming wars

Bulbophyllum lobbii 'Sonoma Gold' HCC/AOS

Bulbophyllum lobbii 'Sonoma Gold' HCC/AOS - Plant photo by Richard LindbergI keep saying that I want to reduce my collection but it never seems to happen. This Bulbophyllum is a recent addition. I went to the SCOS holiday party and came home with 3, this being one of them.

Bulbophyllum lobbii 'Winter' - Flower photo by Richard LindbergThis is a very nice plant. It is awarded and the flowers are big and long lasting. I used to have another variety "Winter" and it was great.

This has six pseudobulbs and it has about filled the pot. There is not room for the next generation. I will divide it as soon as I see the new growth.

Bulbophyllum lobbii grows in Borneo, Indonesia, Malaysia, and the Philippines above 2000'. The species is warm to hot growing, fragrant and blooms in spring.

Cattleya Coquina x Little Sunshine

Cattleya Coquina x Little Sunshine - Flower photo by Richard Lindberg

Lillian got this at the SCOS holiday party. It is a hybrid made be Bob Richardson. He has some very nice Cattleya hybrids. If you see one of them for sale, I suggest you grab it.

Bob has been developing these for many years and is a member of SCOS. We see his orchids at show and tell all the time and they are always a hit.

Rat update

NOID Dendrobium. 6 spikes and very pretty.

When I went into the greenhouse the rat was there waiting for more of that delicious rat bait. He had eaten all that I had put out. There were footprints in one of the glue traps and it appears that he walked right out of it. I got a good look at him since he did not seem to be in a hurry.

On the way home I stopped at Big Box and bought $70 worth of stuff, including an electric trap. All that will be installed today.

The Sonoma County Orchid Society Spring Show and Sale is February 6-7, 2010. I am giving a presentation on backbulb culture and also mounting. I have an hour each of the two days. I am not sure what I am going to say. How do you stretch "Don't fuss with backbulbs and they will sprout" into an hour?

Oncidium Twinkle

Oncidium Twinkle - Flower photo by Richard LindbergNot attached to the mount due to over wateringOncidium Twinkle is a plant that has been here since before the greenhouse was built. It has been on that mount a long time. I know because I haven't done the fishing line wrap method for quite some time.

Although there are four spikes this is not a good bloom. It is typical to have a dozen or more spikes. When I got it down I could see what was wrong. The plant was in the area that got the most misting in the summer. The small roots never got much of a chance to dry.

When the flowers are gone I will re-mount the plant and move it somewhere dryer for 2010.

The flowers are small and white and I found them very hard to photograph. I had several sessions spanning two years before I got that picture.
