Cattleya Laurie Lynn Westenberger in bloom

Cattleya Laurie Lynn Westenberger - Photo by Richard Lindberg

In bloom in Sonoma: Cattleya Laurie Lynn Westenberger. This is the second spike for this plant and it has three flowers. I looked it up at the RHS and found that it is a cross between two hybrids, Cattleya Bob Betts x Cattleya Claesiana registered in 1958. A great classic orchid.

In bloom in Sonoma: Laelia Zip 'Short Stack' x Laeliocattleya Perelli Sunrise.

Lillian's greenhouse in Sonoma is settling down to a comfortable maintenance mode. We hardly ever see bugs and are done with the emergency re-potting. There are a few backbulbs starting to take root and we hope to get those going before long.

Leptotes bicolor var alba in bloom

Leptotes bicolor var alba - Photo by Richard LindbergThe genus Leptotes (Lpt) has six species that grow in Brazil, Argentina and Paraguay. They are small sticklike plants that carry large flowers

Leptotes bicolor grows in Brazil and Paraguay in subtropical rainforest and coastal mountains.

I seem to have lucked into choosing the right spot for this plant. It grows and blooms, no problem.

Orphans on the doorstep

Iwanagara Apple Blossom is the cross between Dialaelia Snowflake and Blc Orange Nugget, and it has a floral fragrance.

I just got four of these, two white and two yellow. They were bought in bloom from a local vendor and they have just stopped blooming. Their main care problem was under watering and indoor light while they were in bloom. These are both things that can easily be remedied.

Two of the plants had enough almost dead flowers to identify the color, but I don't know about the other two. I will have to keep them until they bloom unless I can come up with a creative solution. Since I do know they are one of each, perhaps someone would buy the pair.

I repotted all four and took them to Sonoma. Only one had decent roots and it was overdue for repotting. I up-potted that one. The rest went back in the same pot.

Coelogyne mooreana divisions from last year

Coelogyne mooreana roots - Photo by Richard Lindberg

Coelogyne mooreana 'Brockhurst' FCC/RHS HCC/AOS - Photo by Richard LindbergLast year I bought a badly overgrown Coelogyne mooreana and divided it. I got a satisfactory number of divisions, but as has been my experience with these plants, there was significant root damage.

I tried to be careful. I soaked the plant, then took my time, using my fingers as much as possible to unwind the roots. Still, roots were damaged and many of the divisions had fewer roots than they needed.

The plants have grown enough in a year to have filled the pot with pseudobulbs on top. And when I slid them out of the pot the roots looked really good. I got the next size pot and up-potted, moving the new growth away from the edge.

Lanium avicula microclimate

Lanium avicula - Photo by Richard Lindberg

Lanium avicula - Photo by Richard LindbergThe genus Lanium (Lanm) contains less than 5 species found in northern South America. Grow best mounted on tree fern or cork.

Lanium avicula grows in Brazil, Bolivia and Peru. Blooms spring and fall and needs more light and less water after blooming. The flowers are cute, and the inflorescense looks like a flock of birds.

I got a great plant in bloom last year. After the flowers were done I removed all the leads and left the remainder in the teak basket it came in.

There were six pieces removed, so I spread them around the greenhouse. They are all in sphagnum. Two went with the Dendrobiums for a dryer winter. Two went in teak baskets and regular watering. Two went with the Brassias.

The ones that did best were the ones in the baskets, so now that the warm weather is here, they are all going to be in the wet zone.

Dendrobium violaceum repot and divide

Dendrobium violaceum grows in New Guinea in mountain forests where it can get very bright light. It is cool to warm growing and can bloom just about any time.

I got this earlier in the month at the SCOS raffle table. It was a cute, delicate looking plant. Mainly it was a species I don't have. I have found that raffle tables are an important means of expanding my orchid horizons.

When I unpotted it and removed all the old sphagnum I found great, voilet colored roots. There was a natural division point, so I now have two plants. Mouse over the picture below to see the plant after cleanup.

I looked up the plant at so I have some clue as to what it needs. Still, I am not always able to pick the right microclimate, and some species do better mounted than potted.

I did both. I will get a chance to learn more than I could have with one plant and probably have a plant to sell or trade next year.

For the potted division I used pea gravel. The roots are thin and I am supposing that it will not want to be evenly wet all the time. While pea gravel holds water better than one would guess, it does drain.

Coelogyne mooreana 'Brockhurst' FCC/RHS HCC/AOS

Coelogyne mooreana 'Brockhurst' FCC/RHS HCC/AOS - Photo by Richard LindbergThe genus Coelogyne (Coel) contains 100 species found in all of Asia east of India and Indonesia and Fiji. Conditions vary considerably.

Coelogyne mooreana grows in Vietnam in high mountain cloud forests. It is fragrant and blooms in spring and early summer on immature growth.

This is my "grows like a weed" plant. Every year I take a couple of backbulbs off, move the new growth to the center, and pack in a bunch of fresh sphagnum. By the time a year has passed, the pot is full again.

This year I was able to remove a lead that had started forming two years ago. Instead of sprouting backbulbs, this year I have a small division.

It has a great roots and two new growths. Although it is a little late, it is possible that it could bloom this year. It is very healthy.

Maxillaria tenuifolia starting to bloom

Maxillaria tenuifolia - Photo by Richard LindbergThe genus Maxillaria (Max) contains 650 some species spread throughout the tropical and sub-tropical Americas. They have a single flower. Generally warm to hot growing.

Maxillaria tenuifolia grows in Mexico and northern Central America. It is cool to hot growing and very fragrant.

This plant picture is from two years ago. Right now my plant has a half dozen flowers but it is just getting warmed up and later it will put on a good show.

This species has a strong coconut fragrance but this particular plant has great flowers and less scent. This was a bit of a disappointment to me at first.

I have thought about taking pieces off the plant to sell but they are a dime a dozen on eBay and I don't really have the space.

Colmanara Kilauea 'Pacific Candy Corn' in bloom

Colmanara Kilauea 'Pacific Candy Corn' - Photo by Richard LindbergThis plant is a cute little throw-away from Trader Joe. I tried to look up the parentage and couldn't find anything at the RHS so suspect that one of the parents changed genus thus removing it from Colmanara.

The spike is pretty long for the size of the plant and the flowers are spaced well. I have had it three years I think and it has bloomed at least once every year.

It could have done better. I has grown to a size where it can be divided and so I will un-mount it and make two pieces. I haven't decided about the next step. Probably mount one and pot one.

I know one thing. The tag is going to stay Colmanara.

Laeliocattleya Trick or Treat in bloom

Laeliocattleya Trick or Treat - Photo by Richard Lindberg

In bloom in Sonoma. Lc Trick or Treat is a very popular parent for new hybrids and I see it listed all the time. This is the first time I can remember seeing its flower and I love it!

This is a victim of the renaming wars. It is listed by the RHS as a Cattlianthe (Ctt), Cattleya x Guarianthe.

While I like to follow convention on species, I have a hard time with justifying hybrid renaming. It is very confusing.

Brassocattleya Caprice in bloom

Brassocattleya Caprice - Photo by Richard Lindberg

In bloom in Sonoma. Bc (or as the RHS likes to call it, Rhyncholaeliocattleya) Caprice is just lovely. The picture doesn't do it justice. The flowers are large and showy and fragrant. The grab the eye at once.

This cross was registered in 1981 by Sea God Nursery. This is Raymond Burr's nursery and it is local. It is not an active nursery now, but the collection still exists and can be seen by appointment. A lot of people around here have a plant or two and especially prized is one of Raymond Burr's original crosses.

Laeliocattleya Callistoglossa in bloom

Laeliocattleya Callistoglossa - Photo by Richard Lindberg

In bloom in Sonoma. This is an unusual looking Cattleya flower. It is a cross between Laelia purpurata and Cattleya warscewiczii. I would never have guessed that Laelia purpurata was one of the parents. It is an old cross. I can't find the original date, but I see it used as a seed parent in 1907. It was re-made in 1985 and this plant is probably decended from that rather than the original cross.

New Maxillaria picta specimen plant in bloom

Maxillaria picta - Photo by Richard LindbergMaxillaria picta grows in Brazil and Argentina. It is a high light cool to warm growing plant, blooming in winter and spring.

Someone brought in plants from their mother's greenhouse. I would have bought more than just this one but I wasn't quick enough.

This great specimen is in a 9-inch pot. The tag has a repot date in 2004 and looks as if it has not been turned since. There are a bunch of flowers down under the leaves.

The plant looks healthy and I didn't spot any bugs. There is new growth now and I am planning on taking it apart very soon. I am a sucker for this type of plant. That is how the greenhouse got so full.

Encyclia selligera in bloom

Encyclia selligera - Photo by Richard LindbergThe genus Encyclia (Encycl) contains 240 species that throughout all of tropical America and the West Indies. Intermediate conditions, long dry winter rest.

Encyclia selligera grows in Mexico, the Bahamas and Central America in low altitude forests. It is fragrant.

I bought this in bloom from the member sale table at San Francisco Orchid Society. There was a fern added and it was attractive but grows pretty fast.

I have tried to remove the fern and have learned that the smallest piece of root will allow the fern to get restarted. I am not ever going to add a fern any of my mounts because before long it becomes a mounted fern with an orchid instead of a mounted orchid with a fern.

Bollopetalum Midnight Blue in bloom

Bollopetalum Midnight Blue - Photo by Richard LindbergBollopetalum (Blptm) Midnight Blue is the cross Bollea violacea x (Zygopetelum Blackii x Zygopetelum mackayi)

I got this plant about a year and a half ago in a group of plants from an orchid friend who was downsizing. It bloomed the first spring and is in bloom again and it seems hardy.

At the time, I simply repotted and tucked it away because of the general overcrowding. Now that I have moved some plants to the Sonoma greenhouse I can pay better attention to placement, particularly light requirements.

Oncidium trivia

It is always useful to know where to look for spikes. We know that spikes on Oncidiums come on mature pseudobulbs off of one side. Sometimes there are two spikes, one on each side.

The first spike always comes from the side with the larger leaf at the base.

This is a Colmanara Wildcat 'Leopard' backbulb that just bloomed. Now that I have the pictures, I will cut off the spike and let it use the strength for the next generation. This pseudobulb and the roots are healthy, but small, and the spike is also small, only four flowers.

Dendrobium lindleyi in bloom

Dendrobium lindleyi - Photo by Richard LindbergThe genus Dendrobium (Den) contains 1200 species from all parts of Asia and the Pacific. Some like a dry winter rest, all like to dry out between watering. Flowers are long lasting.

Dendrobium lindleyi grows from India to Vietnam. It is warm to hot growing and needs a dry winter rest. As the flowers mature, the color deepens.

I am very happy about having this plant bloom. I don't do well with Dendrobiums in general and the 'dry winter rest' Dendrobiums in particular. I have had a hard time with just how dry that is.

It turns out it means no water at all. I have a problem emotionally with not watering a plant and physically, since my greenhouse is quite wet.

Colmanara Wildcat 'Leopard' backbulb

Colmanara Wildcat 'Leopard' - Photo by Richard LindbergColmanara Wildcat is Odontocidium Rustic Bridge x Odontocidium Crowborough developed by Rod McLellan in the early 1990s. This is a victim of that pesky reclassification and is supposed to be called Odontocidium Wildcat. But I have to draw the line somewhere.

This is a matter of communication. If I say 'Colmanara Wildcat' everybody knows what I mean, and if I say 'Odontocidium Wildcat' I would get only strange looks.

This plant is typical of the stages of development of a backbulb. Here is the plant a couple of years ago when the backbulb has just sprouted.

The sprout developed into a small pseudobulb. The backbulb used its energy up doing that and died off. The new pseudobulb had developed enough roots to maintain itself and in the next growing cycle produced a new growth of its own.

The next step will be to cut off the original pseudobulb and repot it back into the same pot. The next generation pseudobulb will be back to the proper size.

Notes from last Tuesday

Lowara Trinket 'Peach' x Lc Gaudi-digbyana - Photo by Richard LindbergTuesdays I do greenhouse maintenance in Sonoma. There are lots of Oncidium spikes as well as some Catts blooming. All in all, it is looking pretty good.

One plant I am watching is a Lowara Trinket 'Peach' x Lc Gaudi-digbyana that was taken out of its pot about a month ago. It was one of those that looked OK on top but turned out to have no live roots at all.

It was broken into four divisions which were put back in the same pot together in lava rock. I checked the pieces for root growth and three of them have started. They still need more time before they can be potted.

Brassavola nodosa - Photo by Richard Lindberg

One of the plants there is a large mounted Brassavola nodosa. This piece was sticking out at an odd angle so I trimmed it off and brought it home.

I have never done well with either Brassavola nodosa or one of its popular hybrids, Brassolaelia Yellow Bird. I am going to make more of an effort on this one since it is a healthy piece with good roots.

I am going to mount it. It seems to like being mounted and why argue with success.

Oncidium onustum

Oncidium onustum 'Bountiful' - Photo by Richard LindbergThe genus Oncidium (Onc) contains 600 species from throughout Central America and South America. They grow in a wide variety of environments. If you know a little about where the species grows, the do very well in cultivation.

Oncidium onustum grows from Mexico to Ecuador and Peru. It is warm to hot growing and needs a complete dry winter rest from after blooming until new growth starts.

This plant was in bark and in far too big a pot. All the roots below the top of the medium are dead. The small pseudobulb has bloomed and so must be considered mature. It should be larger than it is.

The ideal is that each generation is as large or larger than the previous generation. Since it is not true for this plant it is close to becoming a recovery plant. But not quite.

One feature of Oncidiums in general is that they grow upward. It is particularly true for this species where the upward rhizome is almost as long as the pseudobulb next to it. They do better mounted, and that is what I am doing with this plant. I chose a fairly small piece to make the immediate proportions better, but I may regret that decision in a couple of years.
