Barkeria spectabilis 'Bob Hoffman'

Barkeria spectabilis 'Bob Hoffman' - Flower photo by Richard LindbergBarkeria spectabilis 'Bob Hoffman' - Plant photo by Richard LindbergMy Barkeria spectabilis is blooming again. This spike with four flowers is about the best I have ever been able to do. I have had it eight years. As you can see, it is surviving, barely. It somehow manages to make a new growth and carry on.

Barkeria spectabilis grows in Southern Mexico, Guatemala and El Salvador on oak trees above 4000 feet. It is cool to warm growing, needs bright light with even brighter in winter and blooms in spring. The genus Barkeria (Bark) contains fewer than 20 species growing in Central America. All need a bright and dry winter rest.

The plant had four solid months of complete dry. It looked as if I had killed it but somehow started a new growth. This year I am going to feed it a little more and see what happens.

Cut a Phaeanopsis Stem?

White Moth Orchid - Flower photo by Richard LindbergAn orchid I get given to me often is the Moth Orchid, a Phaleanopsis from Big Box that doesn't have a name tag. These are sold as an alternative to cut flowers. They are meant to be discarded and replaced, but many people hate to throw out a living plant. I got this one just as the last couple of flowers were about to drop off.

Cutting the old flower spike once the flowers are gone is the best plan for the long-term health of the plant. But leaving the stem on gives the plant a chance to re-bloom. This is unique to Plaleanopsis. Almost all other orchids do not do this.

Two new branches have formed and are about to open flowers. These flowers will be smaller and there will be fewer of them than the original. But I will be able to get a good flower picture. This will go in the Sonoma display window.

Laelia lundii

Laelia lundii - Flower photo by Richard LindbergThis is a 3-pseudobulb backbulb division that sprouted in two places. I potted it last September and wintered it in Sonoma. This plant is in sphagnum moss in a 3 1/2-inch pot. It now has two new growths and a spike.

Laelia lundii grows in Brazil on the coastal mountains. It is warm growing, fragrant and blooms winter and spring.

All my other Laelia lundii divisions are mounted. This one seems to be doing the best of all of them. It has the typical pattern of the first generation of sprouts maturing smaller than the original plant.

Cymbidium Pharlap 'Ruby Glow'

Cymbidium Pharlap 'Ruby Glow'Cymbidium Pharlap 'Ruby Glow' - Plant photo by Richard LindbergThis is the last of the Cymbidiums to bloom. I was surprised by how late in the season all of the bloomed. There were none at all before January.

This plant is in a terrestrial bark mix and a 1-gallon pot. It has a pendant inflorescense with yellow flowers having a red lip.

I bought this in October from Cynthia B. It is very pretty and I like the cascade very much. Does anybody have a nice cascading Cym backbulb that they would like to share? I'm afraid I can't do it as a Cymbidium trade, but if you would consider something else, we can work something out.

Eria mussetter

Eria mussetter - Plant photo by Richard LindbergEria mussetter is what the tag said, as much as I could read it. I wrote a new tag but I can't find any species or hybrid by that name. I was going to try for a flower picture but the flowers are tiny and don't seem to last long.

Eria (Eria) contains 370 species that are found across tropical Asia and out through the Pacific Islands. They have quite varried cultural needs, so just knowing that it is an Eria doesn't help.

This plant is in the Sonoma collection. The goal of that collection is to produce nice flowers for display. The exact name is not important if it produces nice flowers. I am not going to spend any more energy on this plant so I am going to discard it.

I hate to just throw it out if someone wants it. Add a comment claiming it and them go to this page to get my direct email address so we can work out the details. It will be under a pound so shipping will be around $6. No "first time" restriction on this one.

Oncidium sphacelatum 'Marion'

Oncidium sphacelatum 'Marion' - Flower photo by Richard LindbergOncidium sphacelatum 'Marion' - Plant 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, they do very well in cultivation.

Oncidium sphacelatum grows from Mexico south to Venezuela in low altitude rain forest. It is warm to hot growing, but does very well intermediate. It is giant sized and grows long, pendulous spikes of 6 feet or more.

As far as culture goes, this is considered a beginner plant but not a good indoor plant because of the plant size and the length of the flower spike. Having said that, I don't get good results with Oncidiums in either greenhouse.

This is potted in bark in a 4-inch plastic pot. It has four pseudobulbs and one new growth and stands 14 inches above the pot. The newest pseudobulb is the largest but the plant is still quite small for this species.

Vanilla planifolia

Vanilla planifolia - Flower photo by Richard LindbergVanilla planifolia - Vanilla bud photo by Richard LindbergThe Sonoma greenhouse has two Vanilla planifolia plants. I have just noticed two sets of buds on the larger of the two and it is exciting to watch them develop. The flowers will open one at a time. The flower is ephemeral and if I am there after 11 A.M. on the day it opens, I will have missed seeing it. It will be fading and gone by evening.

Vanilla planifolia grows in Florida, the West Indies, Central America and Northern South America. It is warm to hot growing, fragrant and needs bright light and can bloom any time of the year. The genus Vanilla (Vl) contains 100 species growing world wide in the tropical zone.

Cymbidium NOID

These are flowers from two adjacent 5-gallon pots of Cymbidiums. Neither has a tag. They seem to be different hybrids because of the flower color. I was going to list them separately. Now I am not so sure. As flowers have opened more and matured I am seeing the color difference on the same plant. The throat and lip are the same. These may be the same hybrid. I will make that call after I have seen the flower cycle finish.
