Dendrobium hellwigianum

dendrobium dendrobium hellwigianum new guinea orchid Dendrobium hellwigianum is a high-altitude species from New Guinea and is reputed to be difficult to grow.  I have no difficulty growing it or flowering it with cool temperatures and high humidity.  It is an attractive plant with thick, narrow leaves that look a bit like chives to me and the unusually colored flowers come in pairs among the leaves and at the top of the pseudobulbs.  The plant is 10cm tall and the flowers 3cm.  I grow the plant mounted on a small slab of cedar with a pad of moss around the roots of the plant.

Rebuilt Orchidarium

miniatures orchid orchidarium orchids wardian case The last couple of days, I took my orchidarium apart and rebuilt it.  There were several things I was unhappy with and I used the opportunity to make some changes as well.  One thing that needed to be changed was the back.  I had originally used a masonite panel with a finished surface, but that had begun to deteriorate and I needed to replace it.  This time I used 3/16 inch glass.  I was also not happy with the sliding doors which were of plexiglass but which always bowed with changes in temperature and humidity and which even a rigid ...

Dendrobium Mountain Magic

dendrobium dendrobium cuthbertsonii dendrobium mountain magic dendrobium pseudoglomeratum Dendrobium Mountain Magic is a hybrid of the tiny Dendrobium cuthbertsonii and the much larger cane-type Dendrobium pseudoglomeratum.  The plant resembles the larger parent but is much reduced in size by the influence of Dendrobium cuthbertsonii, with 12-15 cm canes and huge flowers that resemble those of Dendrobium pseudoglomeratum.  It is very easy to grow, much easier than either parent, is temperature tolerant and flowers profusely throughout the year.

Dendrobium malvicolor

dendrobium dendrobium malvicolor orchid sumatra This charming little species is from Sumatra.  It is only 10cm tall with clusters of 3cm flowers that appear to be white but have a pink blush.  Because the flowers are pendant, the fact that anther cap is purple is not evident either except on closer inspection.  The plant is quite temperature tolerant and blooms faithfully for me every spring on the older growths.  The growths are on a wiry "stem" with a fattened end that holds several small leaves.

Dendrobium limpidum 'Ashley' CBR/AOS

aos cbr dendrobium dendrobium limpidum new guinea Dendrobium limpidum is from New Guinea and belongs to the Pedilonum section of the genus Dendrobium, a group of mostly semi-pendant cane-type plants.  This species is one of the smallest in the section with thickened canes 10-12cm long.  The 2cm flowers, which do not open very widely, are produced in clusters, and though the individual flowers are quite small, the plant puts on a good show since both the color and number of the flowers are eye-catching and foliage very beautiful also.  My plant was given a Certificate of Botanical Recognition by the American Orchid Society (CBR/AOS).

Scaphosepalum merinoi

ecudaor orchid scaphosepalum scaphosepalum merinoi The Scaphosepalums includes some of the oddest flowers in the orchid world.  Scaphosepalum merinoi from Ecuador is no exception and even the flower buds are oddly shaped.  Like many other species in the genus this flowers successively over a long period of time, so that the ends of the flower spikes begin to take on a herringbone pattern.  The flowers are 6cm across and the flower spikes are 20 cm long.  The plant is from Ecuador and is 8-10cm tall.  It is best grown mounted because of its long flower spikes.

Northwest Orchid Society Show

american orchid society dendrobium pentapterum diodonopsis anachaeta northwest orchid society orchids On Friday and Saturday, April 5 and 6, I was at the Northwest Orchid Society Show in Shoreline, Washington.  I put in a display, but since it was really the same display as in the Mount Baker Orchid Society Show, I did not even take pictures of my display, though the plants won a number of ribbons and two trophies.  These are some of the orchids from the show that I photographed - shows are always a challenge.PHALAENOPSISUnidentified Phalaenopsis hybridsPhalaenopsis philippinensisPhalaenopsis Chih Shang's Stripes 'Bedford'Phalaenopsis leucorrhoda x philippinensisPhalaenopsis Sogo Ponsai 'Jane'CATTLEYA ALLIANCESchomburkia superbiens 'Lula'Epidendrum stamfordianum and Epidendrum horichianumCattleya speciesLaelia crispataLaeliocattleya ...

Masdevallia caudata

colombia ecuador masdevallia masdevallia caudata orchid Masdevallia caudata is amazing.  The plant is only 8cm but the flowers are 16cm from tip to tip and can be even larger.  Their coloring is also unique and beautiful and very difficult to describe, but the pictures certainly show what I mean.  The name refers to the very long "tails" of the flower, the caudae.  They are 7-8cm long.  The plant is native to Colombia, Ecuador Peru and Venezuela.  The flowers have a rather strong scent as well, which I find difficult to place but also quite unpleasant.  Someone described the scent as that of artificially flavored raspberry drink, ...

Dendrobium cuthbertsonii bicolor

bicolor dendrobium dendrobium cuthbertsonii new guinea orchid This is one of many Dendrobium cuthbertsonii plants I own and one of several with bi-colored flowers.  This one is a smaller plant as this species goes, though they are all tiny, but has larger flowers than some.  It's coloration is similar to another plant I own and which I recently posted, but the color is much more intense. Dendrobium cuthbertsonii is from New Guinea, from high altitudes, and is cool growing.  It has beautiful "pebbled foliage as is evident in some of the photos. Read more

Phalaenopsis violacea var. alba

malaysia orchid phalaenopsis phalaenopsis violacea sumatra Once Phalaenopsis violacea begins to bloom, it is seldom out of bloom, since the flower spikes continue to lengthen and produce flowers, usually a few at a time.  The species is from Southeast Asia and is very fragrant, especially when it is warm.  My plant is still quite small but already has two flower spikes.

Masdevallia naevia

ecuador masdevallia masdevallia naevia orchid pleurothallid Masdevallia naevia belongs to the Caudatae section of the genus Masdevallia, a section that includes some rather awkward-looking flowers of which this is one.  The flowers are beautiful in their own way, but I always feel that they are held rather stiffly above the plant and that the flowers themselves are rather stiff and awkward compared to other Masdevallias.  The plant is 10 cm and the flowers the same size.  It is from Ecuador and named for the purple spot on the dorsal sepal (naevia means "birthmark").

Porroglossum meridionale

orchid perù pleurothallid porroglossum porroglossum meridionale Porroglossum meridionale is another species from a genus of insect-trapping flowers with hinged lips.  When disturbed by a small insect the lip suddenly snaps up trapping the insect against the column and effecting pollination.  I've provided pictures of the flowers with the lip in both positions.  This plant is 6 cm tall, the flower spikes 10 cm in length, and the flowers 1.5 cm.

Dendrobium vexillarius

dendrobium dendrobium vexillarius new guinea orchid oxyglossum This is a first bloom seedling, blooming on a very small plant.  Both plant size and flower color are extremely variable with this species.  I am very pleased with the flower color which can be red, orange, yellow, white, green, blue, grey, violet, purple or pink.  The flowers are a little less than 2.5 cm.  I am eager to see if how large the plant grows since this species can range from 3-40 cm.  If it stays small it is probably var. elworthyi.  It is from the highlands of New Guinea, the Moluccas and New Ireland, is cool-growing and belongs ...

Angraecum urschianum

angraecoid angraecum angraecum urschianum madagascar orchid Angraecum urschianum is a tiny species from Madagascar.  The plant is only a couple of centimeters tall with flowers that are as large as the plant and a flower spur or nectary that is huge for the size of the flower, nearly 15 cm in length.  The flowers are probably pollinated by a night-flying moth with a tongue long enough to reach the nectar in the bottom of the spur.  My plant is a seedling blooming for the second time.

Porroglossum dreisei

ecuador orchid pleurothallid porroglossum porroglossum dreisei The last post was of a Porroglossum.  Here is another, this time Porroglossum dreisei from Ecuador and another small species.  The plant is 4 cm, the flower spikes 12 cm and the flowers 1.5 cm and blooming successively, several to a spike.  Like the other Porroglossum species this has a moveable lip that snaps up and traps an insect against the column effecting pollination and I've included pictures of the flowers with the lip both open and shot.  I thought about titling the post "Arms Akimbo" since the flowers look like a little man with an elf hat and his ...

Dendrobium seranicum

dendrobium dendrobium seranicum new guinea orchid oxyglossum I have two plants of this species, one plant awarded, the flowers of which are not quite as brightly colored as this.  It is a spring bloomer and blooms well on a rather attractive plant.  The individual growths are 8 cm and the flowers 3 cm.  The species is from the highlands of Papua New Guinea and belongs to the Oxyglossum group of Dendrobiums.The other plant has flowers that are a slightly paler pink and the lip does not have the bright red tip.  Both, however, fall within the range of variation for this species.  The photo below shows the ...

Porroglossum tripollex

ecuador orchid pleurothallid porroglossum porroglossum tripollex Porroglossum tripollex belongs to a genus of plants closely related to Masdevallia, but all having a moveable, insect-trapping lip.  They are usually small plants with rather long flower spikes that hold the small flowers well away from the plant.  When the lip is disturbed it eventually snaps up against the column of the flower trapping some tiny insect against the column and effecting pollination.  This species is from Ecuador, is 3 cm tall and has 1.5 cm flowers on 6-8 cm flower spikes.  The first three of the following photos show the flower with the lip "unsprung."  The last two ...
