Potinara orchids, and related hybrids

I discussed Dendrobium, now something from the Cattleya alliance, Potinara. Another will be in the same shipment as Dendrobium Yellow Song Canary. The Potinara varieties seem suited for home culture, due to hybridization and small size.

Potinara is a manmade genus (nothogenus) created from several species of Cattleya-type orchids. Potinara consists of grandparents from Brassovola, Cattleya, Laelia, and Sophronitis.

It gets complicated. With genetic testing, some species have been moved to different genera, and some have been renamed. So... this is rephrased from Richard Pippen, Ph.D , Professor Emeritus, Western Michigan University, Naples, Florida

Some Brassasavola have changed. Now Brassavola digbyana is Rhyncholaelia digbyana. 19th century botanical sketch here is from Wikimedia commons. The Rhyncholaelia digbyana is a Mexican or Guatemalan species, and contributes larger, ruffled lip, and may contribute fragrance. from orchidspecies.com.

Other Brassovola parents were shuffled around, so some are now Brassocattleya or Brassocatanthe.

Rhyncholaelia provides fragrance and highly ruffled characteristics for the lip.

*Brazilian species of Laelia were merged into Cattleya.
*Sophronitis was merged into Cattleya.
This drawing is "Sophronitis crispata as Laelia flava". How's that for confusing? " Laelia flava has brightly colored yellow, star-shaped flowers. Color ranges from yellow to pale yellow. Some individuals have small red spots near the base of the petals. The lip is frilly. The flower spike reaches 25 cm above the foliage and has 4 to 8 flowers near the tip." from verdantgreenla.orgI think these would contribute warm colors, yellow, orange, or red, and multiple flowers.

*Cattleya auriantica, C. bowringiana, and C. skinneri were split out of Cattleya and are in the new genus Guarianthe. This sketch os Sophronitis coccinea as Sophronitis grandiflora. OK. The former Sophronitis coccinia, now Cattleya coccinia comes from Brazil. Info from mirandaorchids.com. Here we find red or orange coloration, clusters of flowers.

Guarianthe skinneri as Cattleya skinneri.

So Dr. Pippen gives the example, Potinara Burana Beauty, a cross between Potinara (now Rhyncattleanthe) Netrasiri Starbright and Cattleya Netrasiri Beauty, which went from
Brassavola x Cattleya x Laelia x Sophronitis = Potinara to Rhyncholaelia x Cattleya x Guarianthe = Rhyncattleanthe (Rth.)

Not that it is going to matter to the home grower - the species have been so jumbled, traits from multiple ancestors from multiple places contribute. See original link from Manatee Orchid Society for much more mind boggling detail. Where it matters to me, is that I like to look for the ancestors and see what the original plants looked like.

These are from HausermannOrchids.com and are the others in my order. Potinara"Cheryl Winkelman" Who knows what were the original progenitors, and with so much genetic scrambling, it may not be possible to find out. I find it compelling that the lip has a pattern similar to that seen on the Guarianthe skinneri sketch.

Sophrolaeliocattleya Jewelbox orange. Not Potinara, but with some members of the mix.

The photos don't show the entire plant, that will have to wait until I can do it myself. Assuming they survive and bloom in my hands.

Dendrobium nobile

Dendrobium nobile, 19th century lithograph. Some people drink. Some gamble. Some smoke. When I have a hard day, week, month, I think about gardening. This year with so much rain, and chilly, the outdoor garden is more neglected. That leaves indoors, and lately, orchids.

Now that my Dendrobium nobile is in bloom, I became more interested in this species, and researched its development into the modern hybrids. It's interesting to read. Ning is in Shanghai with the better camera, so this is not as clear, but this is the general idea.

Photo and information below are from Yamamotoorchid.com.
In the early 1950s, Jiro Yamamoto began working with Dendrobium nobile in tissue culture. He went on to develop new hybrids, refined growing techniques, and expanded to greenhouses in Japan, Hawaii, and Thailand. Yamamoto Orchids has developed more than 4,000 registered hybrids. Many of the modern ones are tetraploid, a genetic duplication that can mean more robust plants, with larger flowers.

Yamamoto is now a major orchid business, supplying their flowering Dendrobium plants around the world. While I can't say that my NOID, Trader Joe's Dendrobium plants are from Yamamoto, I strongly suspect that they are.

The Yamamoto tetraploid hybrids and sophisticated growing techniques resulted in an impressive transformation of this plant. The orchids are greenhouse grown in Hawaii, starting with the highly developed hybrids, then propagated through tissue culture, then grown in clusters and brought into bloom. I'm not sure I want the top-to-bottom flowering plant in my own collection. They are beautiful, but possibly too much for my little plant room. However, I think these varieties are so developed as far as ease of growth, compact size, and flower shapes and colors, they make a great plant in my home collection. I love seeing the growth habit, with the twisting, knobby canes and succulent leaves. I don't know if my plants will be as stout as the greenhouse-grown plants, but I took a lot of pride that I brought specimens into bloom. In all honesty, that's probably due to Mr. Yamamoto's efforts, more than mine.

From the Kew Gardens website, "This species occurs largely in deciduous forests between 1,500 and 2,000 m elevation in the foothills of the Himalayas and surrounding areas. It is recorded from India, Bhutan, Nepal, Myanmar, Thailand, China, Laos and Vietnam. It prefers bright sunlight, which is provided by deciduous trees which lose their leaves in the autumn." also "This species was first known from China and was later imported for cultivation into Europe from India. Many horticultural varieties of this species were named in the 19th century. The specific epithet 'nobile' means noble..."

Dendrobium is used in Chinese herbal medicine. Also some nice photos here. "It is one of the 50 fundamental herbs used in traditional Chinese medicine, where it has the name shí hú (石斛) or shí hú lán (石斛兰)." Assuming that there IS a medicinal property to this plant, the changes in domestication, hybridization, and culture, would have no predictable effect on that property - there could be more, less, or none. Apparently, the nobile orchid is regarded as an aphrodesiac. Here, it states hypotensive, antipyretic, analgesic (basically, aspirin and a blood pressure pill). Also "Nourishes the Stomach; Promotes generation of Body Fluids; Nourishes Yin; Clears Heat". Also here. "A prepared Dendrobium compound decreases the level of blood glucose, promotes the secretion of insulin and increases insulin sensitivity in diabetic rat models and patients. Shi-Hu is also a main substance in the Shi-Hu Ye Guang Wan, a preparation for cataracts, poor sight and other eye problems... alkaloids in the Dendrobium species, such as dendrobine, are a weak anti-pyretic and analgesic... may increase immunity, decrease the oxidant stress in aging and have anti-cancer activity.... recently used in the treatment of stomach and lung cancer.

Well, better this than tiger testicles or rhino horns, or whatever.

It's been another very hard week. As I stated at the beginning, this is one of my outlets. The pic is from orchidweb.com - more realistic - but the plant is ordered from Hausermann orchids. This is my 4th order (or 5th?) from them. I must like that place.

This pic isn't that attractive. I'll have to take my own pic. Web pics may not look like what I get, because of differences in growth, lighting, and color changes in the camera, so I won't really know until (if) it blooms in my hands. Probably in about 9 months, my guess.

The variety originates from Yamamoto orchids, Dendrobium Yellow Song 'Canary'. From the Yamamoto Orchids site, "A new variety is in stunning golden yellow. It has won a new status of rarity, since flowering on new canes are guaranteed, yet that is a rare quality for yellow inflorescence... It flowers well, with 4～5 or more blooms on each node. Canes grow fast and multiple shoots can develop producing golden blossoms in profusion, resulting in a bouquet full and festive. Its robust character makes the care very easy. We can recommend even for novice growers. Even a short cane in 5cm can bear flowers." Of course, their photo shows an awe-inspiring blossoming plant, but as I noted earlier, I'm happy with the smaller number of flowers, held more loosely, that I'll probably have.

Kitchen Garden Log: Barrel planters, hens, seedlings

I may hve put the peppers and eggplants out too soon. They are not looking as good as I hoped. We'll see if they perk up.

The 5 hens are producing 4 eggs daily. Someone is shirking. If I could figure out who it is, I would put her on a "Work Improvement Plan". As it is, the others seem to be covering for whoever it is. At least absenteeism is not an issue. They don't have a choice on tht. A good leader will reward them. Today I've been doing homework all day, so could not pull weeds for them, but I did put a watermelon rind through the shredder on the food processor - in seconds, a big batch of tasty morsels.

Potato barrel. My largest concern now is that I planted too many. As always, "we'll see"

Seeds planted 7 days ago, zucchini, squash, and cucumbers. I'm leaving them on the deck in the sun. It's overcast. When one set of leaves is developed, I'll plant them.

Peppers. They are sulking. Probably too cool, but with warmer weather now, maybe they'll start up again. The purple plant is basil. There are some little radish seedlings, I'm not sure how they will do. In the back, seedlings of bunching onions. I'll let them get bigger then pull them.

Kind of a mix now. Purchased eggplants, bigger. The lettudce and mesclun will be done in a week, leaving a lot more room. The heliotrope isn't planted yet, this may not be the right spot. Very fragrant. These onions will be allowed to develop tops, unless Ning pulls them. By tops, I mean these (Egyptian walking onions) develop clusters of baby onions on the top of the stalk, instead of a flower. Those are used to plant the next crop, for indefinite perpetuation of the variety. If these do get pulled, I have others in the borders that will make plenty of new sets.

Orchids - Dendrobium nobile blooming

I've been debating leaving orchids ouside. Daytem temp today 72, overcast. Night temp 50s. Concern is exposure to excessivde sun if not cloudy.

I can't beleive this bloomed under my care. How cool is that!

Ditto!

Iwanagaara continues to bloom, as does Vyl. and one paph maudii - must be 3 months for that one.

Irises have started blooming.

Each one that I look at is my favorite. Then another opens and THAT one is my favorite.

Inuendo. The first that I started here, now in their 9th year. They've been divided and moved a few times, and a few keep returning to the original location.

Edith Wolford. I never like photos of this iris, but in person it's amazing.

China moon.

China moon again. Sometimes close-ups are nice, but it's also important to see them in context of the garden. I'm not crazy about all of the flower pictures that show a decapitated bloom without including the rest of the plant or surroundings.

Bumblee Delite. A small variety. Lots of grass intermingled in this one.

Each year, I think the effort isn't worthwhile. Irises are difficult to keep clean, because their roots are so shallow, and the rhizomes are at ground level. This makes them almost impossible to weed. Then when they bloom, I just feel awe. They are worth it.

I have a few that I tried to start last year, from store purchases of rhizomes. They are a long, long way from blooming size - those little dried out rhizomes take a long time to become a blooming size plant, and many die over the winter. If I can keep them going, one might bloom next year. The other will likely take 2 years.
