Phalaenopsis Gold Tris 'Desk Pot' keiki in full bloom

Phalaenopsis Gold Tris 'Desk Pot' 
About 3 months after I first noticed the start of a spike, my little Phal Gold Tris Keiki is in full bloom!  The flower spike is bigger than the orchid itself, with 4 full-sized yellow flowers. Of course, the mother plant produces larger numbers of flowers and multiple spikes, but this is still one precocious bloomer!

The color is less saturated than usual, most likely due to the very warm weather of the last month.

A group of botanists from the Chinese Academy of Sciences, in collaboration with HponkanRazi Wildlife Sanctuary in Myanmar and the Forest Department Ministry of Environmental Conservation and Forestry in China have described a new species of Coelogyne which grows in the Nat Ma Taung (Mt.Victoria) National Park.

This epiphytic orchid produces brownish-red flowers that are about 0.5 inches in length (1.2 cm). It blooms in April and May. The species is named after the Mount Victoria region of Myanmar where it was found.

New orchid species discovered in Thailand: Dendrobium Obchantiae

There are an estimated 30,000 species of orchids, and hundreds of new orchid species are discovered each year. A group from Chulalungkorn University in Thailand and the Department of National Park Wildlife and Plant Conservation published a paper in April describing a new species of dendrobium which grows in the mixed deciduous forests of northern Thailand.

Paphiopedilum Adam Hausermann x Duncan York (#2) has really grown

Paph Adam Hausermann x Duncan York (6 years after purchase)
I repotted my two paphiopedilum seedlings today, and was shocked to realize that 6 whole years have passed since I bought these orchid seedlings.  While the growth on seedling #1 has remained rather stunted over (years of dehydration by neglect circa 2013-2015 haven't helped), the plant on the left has managed to establish a healthy root system, and has really grown up to what I think should be flowering size.


Evidence of damage on orchid
However, even this large and healthy plant bears multiple signs of past damage.  One leaf was half chewed off by my mischievous cat, when I had dared to try growing this orchid on a windowsill instead of safely within a glass terrarium.  Several of the longer leaves are bent and broken from being tossed around during multiple moves between apartments over the years.  Another leaf is significantly shorter than it should be--evidence that I had failed to sufficiently water this orchid during that period of time.

Even my presence is not a deterrent against attack
I decided to repot the paph because it has been a long while since I've refreshed its media.  Also, the plant was a little top heavy in its pot, and would frequently dry out too much between waterings.  I had noticed a new growth developing at the base of the main plant, and this seemed like a good time to switch up to a larger pot.
New growth on paphiopedilum orchid
The paph had a healthy clump of roots, which explains its great recent growth. I tried to be very gently in the repotting, disturbing the roots as little as possible.

Here is the paph after repotting.  The final pot is perhaps a little bigger than it should be, but I didn't have an intermediate size between the old pot and the new.  I had a problem with the orchid completely drying out between my weekly waterings when it was in a smaller pot, so hopefully this larger size will keep a better balance of moisture.  And if I'm really lucky, perhaps I'll see it flower by end of summer.

Tsubotaara Melinda Marie 'Blue Fairy'

Tsubotaara Melinda Marie 'Blue Fairy'
I came across this striking blue orchid at the 2018 New York Orchid Show.  The bloom was hidden behind a glass enclosure, labeled with a genus I had never seen before: Tsubotaara.  What kind of orchid could this be?  

According to the International Orchid Register, Tsubotaara Melinda Marie is a cross between Pabanisia Eva's Blue Amazon and Zygonisia Cynosure.  The hybrid was registered in 2010 by Kalapana Tropicals, a Hawaii-based orchid wholesaler.  A relatively miniature plant, this hybrid blooms with beautiful, oversized bluish flowers.

The full genealogy of Tsubotaara Melinda Marie includes contribution from four different orchid genera.
Curiously, I could not find any photos of Zygopetalum graminifolium while researching this genealogy.  The image depicted below is gathered from a print from Jean Linden, a prominent orchid botanist from the 19th century. This is a species that does not appear to be frequently cultivated or photographed by orchid enthusiasts.  Nor was this ever a particularly popular species among orchid breeders: Zygopetalum Skippy Ku is the only hybrid registered with Z. graminifolium as a parent.

And here is a closeup of the contributing species.

Aganisia cyanea shares the greatest resemblance to Tsubotaara Melinda Marie, which makes sense because it was crossed twice into this hybrid.  However, I can see how features from both Zygopetalum and Pabstia genera are represented in the final hybrid. Tsubotaara Melinda Marie is a great example of how orchid breeding may be used to borrow traits from very different orchid genera to produce a truly distinct new flower.

2018 New York Orchid Show


Hundreds of orchids hand from a translucent display at the 2018 New York Orchid Show
The New York Orchid Show is my favorite annual event in the city.  This joyous celebration of orchid beauty is a yearly signal that another cold, dark winter is nearly over.  The show opened today, at the New York Botanical garden.
It's possibly one of the most popular events at the New York botanical garden, and by midday the conservatory is packed with crowds.  This year, I woke up early to be one of the first people to enter the show on opening day.
Get to the conservatory before 10 AM to avoid the crowds
The Orchid Show features hundreds of orchid species and hybrids, presented in intricate displays.  This year's production is designed by Belgian floral artist Daniel Ost.

Each year, the displays follow a different theme.  This year, the recurrent element was these meshes of clear plastic tubing high up in the conservatory canopy.  These clear loops certainly catch and scatter the sunlight onto the orchid blossoms.  They also reminded me of a tangled garden hose....

This is just a small fraction of the orchids on display today.  The show runs until April 22, and is absolutely worth a visit.

Flower spike on a tiny keiki

A 1 year old phalaenopsis keiki
I first wrote about this Phalaenopsis Gold Tris keiki just over a year ago.  Keikis are orchid clones that sometimes grow on a mature orchid plant. Late last summer, when its roots had grown over 3 inches, I cut the keiki from its mother orchid, and planted it in the pot shown above.  The little orchid has more than tripled its roots system since then, but hasn't done much growth with its two leaves.

flower spike on a 1-year old keiki
Today, I noticed a green nub growing to the side of the orchid's base.  Much to my surprise, this wasn't some errant root, but actually a tiny new flower spike!  Although I have heard before that keikis sometimes flower within a year of growth, I never expected it from an orchid this small.  Its flowers would be almost as big as the entire orchid plant!

I'll be watching closely to see how this flower spike develops.
