Speaker: Sam Tsui, "Growing the group Brachypetalum"
Join the NWOS in
welcoming Sam Tsui owner and operator of Orchid
where he is considered the foremost breeder of
Paphiopedilums in North America. Sam will be
sharing his secrets and tips on growing the
group Brachypetalum with us. Sam will also have
some of his wonderful plants for sale.
Orchid Inn, Ltd is owned and operated by Sam
Tsui and his wife Jeanie. They started growing
orchids in the early 1980's and it has always
been their passion! Sam started
breeding/hybridizing in the early 1990's and
eventually started the home-commercial business
"Orchid Inn" in their basement and greenhouses
attached to the house. As the business grew,
they purchased a six acre property and built
their first commercial 6,000 square greenhouse
in 2004. Currently they make over 300 crosses,
produce 4,000 to 5,000 flasks or approximately
100.000 seedlings annually.
In the past 25 years, Sam has been very active
in the orchid world by traveling to shows,
promoting sales, and lecturing. Sam currently
fills orders from around the world and attends
over 20 orchid shows/conferences a year. He also
does approximately 25 Paphiopedilum
programs/lectures to orchid conferences,
societies and groups annually in the USA,
Canada, Japan, Australia and Europe. Over the
past 24 years, he has judged at the Japan Grand
Prix, the world's largest orchid show.
Hybridizing is Sam's passion. He emphasizes
Paphiopedilum species, Brachypetalum,
Parvisepalum and Multifloral hybrids. He only
selects the best, most vigorous parent plants in
his collection for breeding/hybridizing. He
continues to improve his breeding stock by
selecting plants or flasks from his fellow
orchid growers that he believes are outstanding
examples of their type.
As a result of Sam's breeding program, his
orchids have been honored with approximately two
hundred and Seventy five awards (as of May 6,
2017) from the American Orchid Society,
Cymbidium Society of America and European Orchid
Congress. His most prestigious awards include
Fifteen First Class Certificate (FCC/AOS)
awards; four Cultural awards including a 93
points Certificate of Cultural Excellence (CCE/AOS)
award; and seven breeder Award of Quality (AQ/AOS)
awards. All these awards are from American
Orchid Society. Last but not the least, one of
their recent Paphiopedilum rothschildianum
sibling cross have been awarded with two GM/DOG
and also the Grand Champion at the 2017 Dresden
International Orchid Show in Germany.
Bring your blooming Orchids so everyone can enjoy them.
Members may bring up to 10 plants to sell. Include an
extra tag with your name and the price in the plant.
raffle will be held as usual. Win a new orchid for your collection
while supporting the Scholarship Fund.

NWOS Fall Show and Sale Nov. 4th & 5th
The Fall Orchid Show at Swansons Nursery (9701 15th Ave NW, Seattle), is
fast approaching. This AOS-judged show will be open to the public
on Saturday from 9-5 and on Sunday from 10-4.
Volunteer and Show Information
Our Show is coming in just one month, and we still need volunteers to
help out with pretty much all tasks. Signup sheets will be at the meeting, but if you are not able to come,
please send an email to ShowRegistration@nwos.org with your preferred
task and shift time. Choose from
http://newsletter.nwos.org/Show2017 for Pre-registration forms,
downloadable posters, and other general information about the show.
Even though we'll have sign-up sheets at the meeting, here's a rundown
of some of the opportunities to help out.
Setup on Friday, November 3rd, noon to 6pm
Move benches into place. There will be the display area, sales booths,
and the Society sales area. George Grantham is in charge.
Once the benches are in place, the Society will be putting our display
together. Members should plan on bringing their plants around 2pm,
getting them registered, labeled and in place. Cylvia Grantham (and
George, of course) will be in charge.
Vendors will need help setting up their sales areas, and their displays.
I'm sure they will all welcome assistance with moving plants, getting
their displays ready, entering plants, etc.
Help to register plants and print out tags for display
plants. A computer with a spreadsheet program, like Excel or Open Office
required. Thumb drives a plus.
Ribbon Judging (Saturday 9:00am)
Join the AOS judges, and your fellow society members to award ribbons
throughout the show. It’s fun and easy. Don’t worry about being an
“expert,” this is a great opportunity to learn, as well.
Cashiers - Friday (4-6pm), Saturday and Sunday all day
Run the Society sales through the cash register. We only have one
register now, but it's helpful to have someone to prep the plants (pull
tags, bag them up, etc). We need to have at least one person on this job
at all times.
Welcome visitors to the show area. Direct them to the show, vendors,
sales areas. Answer questions, shake the donation jar. The front table
will have society information, applications, demonstration magazines,
culture sheets, etc. There will also be an AOS display with AOS
information and applications. These two may be combined.
These volunteers will also circulate through the show areas, talking to
visitors, and providing some security for the displays.
Be available to repot plants for visitors. We will be asking for
donation only, but a suggested amount will be posted ($xx for such and
such size pot). You can do the repotting for people, or guide them
through the process. There will be potting mix and maybe some old pots
available, but let them know that Swanson's sells nice pots.
There may be some times or opportunities to have a group potting
demonstration in the seminar space.
Share your knowledge with others. It's easy to talk in our
informal setting to people who are truly interested in hearing about
your experiences growing orchids.
We would like to have at least three or four talks each day. We
currently have talks on greenhouses, Paph and Phrag culture, and
Some other topics we've had in the past are windowsill growing,
supplemental lights, and re-blooming grocery store orchids Any other
suggestions would be welcome.
Members can also sell their individual plants through the society.
Orchids for sale in the members' sale area must be marked with a
removable tag bearing the price and the seller’s name. This tag is
in addition to any plant identifying tags and will be removed at the
time of sale and used to calculate the seller’s total. Vendors
must price items clearly and legibly on this tag. Each member
selling must fill out the 'Member’s Sale Table Form' prior to placing
items for sale. All sales are subject to a 15% sales commission.
NWOS members who wish to sell must have at least one high quality
blooming plant in the NWOS display and work at least one show shift.
Breakdown (Sunday 4pm-6pm)
When the show’s over, we need to clean up, pack everything out, and get
the greenhouse space back in order for the nursery. This is very
important, so they’ll let us come back next year.
1. Break down the NWOS display, and organize the plants so they get back
to the right owners.
2. Help vendors and visiting societies pack up and get their plants
loaded into cars or vans. Some of them may be heading home, and need to
get on the road as soon as possible.
3. Sweep the floors, pick up the trash, and make sure everything’s in
We're looking forward to another successful and enjoyable show this year.
I'd also like to send out a special thanks to all the Show Committee members.
Abigail Chang, President
Volunteers Needed for Our Show Display
We are planning on a large area at our show for the NWOS display and we
will need lots of plants to fill the space. It is especially important
this year that we have a large display because we have fewer vendors and
therefore fewer displays. Please bring your plants to Swanson's Nursery
on Friday afternoon. If you are unable to bring your plants Friday
afternoon you may arrange with me or another member to bring your
plants. Please see elsewhere in the newsletter information on
registering your plants. This information will also be available on the
NWOS website before the show. If you are unable to register your plants
in advance (preferred), you can register them on Friday when your bring
them to Swanson's.
Please make sure your plants are groomed, staked if needed, and insect
free. If the plant is tipsy, it is very helpful and much safer for your
plant it you place in a larger heavier pot for stability. Each plant
should have your name on the pot or on a tag and you should bring a list
of your plants with plant names written clearly and in full.
Feel free to contact me if you need help getting your plants to the
show, and also I would like to hear from you if you would like to
participate in planning and setting up our display.
George Grantham, 2nd Vice President
Wanted: Show Trophy Sponsors
Our 2017 Fall Orchid Show & Sale is an
AOS judged show. In addition to any AOS awards, we hold a Ribbon Judging
session where orchids in various categories are given first, second and
third place awards. Each year, a plethora of ribbons are awarded
by our judges. Of all the First Place (blue) ribbons awarded, the "Best
of" each plant category is determined and given a Trophy along with a
cash prize of $25. The "Best of Show" is determined from all of the 1st
Place ribbons and Trophies.
Please consider sponsoring a Show Trophy. It
is a fantastic reward to those who have cared for their orchids and grown
them to perfection. It's also a nice incentive for them to share their
blooms at our show. It allows both us and the public to see the very
best our club has to offer. For those that may not be able to
volunteer at the show, it's an alternative way to support our society.
I am looking for people and/or companies to sponsor one or more
Trophies. I can take cash or checks. The cost is $25 per Trophy or, in
the case of the "Best of Show", any amount will do. Please contact me at the
October Meeting to reserve your spot.

Gables, Florida, to suffer no major damage inside the buildings and are
now back to business as usual. We are blessed to have a staff that truly
cares about the well being of our organization and are grateful for
their extraordinary efforts during this terrible event. Unfortunately,
the Gardens suffered all the devastating effects of Irma and have a long
path to the restoration of many felled trees, damaged collections and

When Good Orchid Buds Turn Bad
Here’s an article about “Bud Blast” by Susan Jones that appeared in Orchids
magazine back in July 2003. It’s just a useful today as it was back then.
It can be heartbreaking to watch helplessly as long-awaited orchid buds
brown, die and drop instead of becoming those much-anticipated flowers. Bud
blast, when buds wither and fall from an otherwise healthy plant, may occur
through any of a number of causes. Buds are the most sensitive part of an
orchid, and are easily affected by unsuitable conditions in the growing
environment. Cattleyas, phalaenopsis and dendrobiums seem particularly
susceptible to this problem. The most frequent reasons for this are as
WATER Under- or over-watering is a common cause of bud blast. If a
plant becomes too dry, it may withdraw moisture from buds as a survival
mechanism. Overwatering can damage the orchid’s root system, with the end
result being a lack of water to the plant. As with under watering, when the
plant is unable to absorb sufficient quantities of water, it will withdraw
water from the buds, bringing about their demise. Budding Cattleyas are
particularly sensitive to overwatering, which can cause buds to blacken and
die while still in their sheath. Water that is allowed to sit on buds or in
bud sheaths provides the perfect environment for fungi and bacterial growth,
generating rots that will blast buds. Watering with cold water can shock a
plant, causing bud drop.
TEMPERATURE Temperature extremes or rapid temperature changes are
often a culprit in bud blast. If a budding orchid receives drafts from a
window, an air conditioning or heating vent, or even a rush of air from a
hot oven, it may drop buds. Similarly, buds may blast when exposed to
temperature fluctuations that occur when taking a plant in from the car or
outside during hot or cold weather, bringing plants back into a heated house
after a summer outdoors, or temperature extremes caused by running heating
or air conditioning for only part of the day.
ATMOSPHERE Orchid buds are sensitive to fumes from paint, natural gas
leaks and other chemicals. Once pollinated, flowers generate methane gas,
causing them to collapse and saving energy for seed production. Methane or
ethylene gas from other sources may also trigger bud or flower collapse.
Ethylene gas given off by ripening fruit; gas leaks; inefficient burning of
gas stoves or heaters; engine exhaust; cigarette, cigar or pipe smoke; open
fires; smog or air pollution can also cause bud blast and age and distort
LIGHT If lighting available to its developing buds is inadequate, an
orchid won’t flower properly. Low lighting can cause buds to abort. Too much
lighting may also cause trouble; direct sunlight on developing buds can
overheat and desiccate them, leading to bud blast.
CHEMICAL DAMAGE Fertilizer, fungicide or pesticide applied at dosages
above a plant’s tolerance or in a manner inconsistent with manufacturer’s
instructions may damage buds, causing them to drop.
HUMIDITY Developing buds need high humidity. If their environment is
too dry, or the ambient humidity fluctuates a great deal, buds may be
adversely affected and drop.
INSECTS Aphids and thrips can cause bud blast. These insects feed on
flowers and flower buds, sucking the plant juices. The buds of infested
plants fail to develop properly, dropping from the plant or opening to
damaged and disfigured flowers. Thrips can be controlled using Diazinon or
Malathion. Aphid control often involves not only eliminating the aphids
themselves, but also the ants that farm them. Insecticidal sprays and
sugar-based ant baits are recommended. For a few aphids, dab with a cotton
swab soaked in rubbing alcohol. Other means of control include insecticidal
soaps, horticultural oils (Neem or Sunspray), growth regulators and chitin
inhibitors (Enstar II), Pyrethrum-based insecticidal sprays, stronger
insecticides (Malathion), and systemic insecticides (Orthene, Shield).
Repeat any treatment method twice after the initial application at seven- to
10-day intervals to kill successive generations. Test new controls on a
small population of plants before widespread use. When using insecticides,
check labels to be certain the insecticide works against the particular pest
and that it is approved for use on orchids. Always use any chemical in
strict accordance with manufacturer's instructions.
GENETICS Occasionally, even under perfect cultural conditions, an
orchid will continually abort buds. There may be a genetic mutation
responsible for its inability to produce viable blooms, in which case the
plant should be discarded.
Susan Jones was the assistant editor of Orchids and editor of the Awards
Quarterly during the late 1990s and early 2000s.
(Please note that the AOS does not endorse the use of any specific chemical
agents. If you choose to follow recommendations given by a contributor make
sure to adhere to all local, state and federal laws in the use of these
agents. Take the time to learn how to use them safely and follow
manufacturers usage instructions.)
Report from the September Meeting
Joe Grienauer receives his AOS
of Appreciation for Outstanding Service
Commitment to the NWOS
opened our meeting
a call to vote on the proposed bylaws. She asked for people to
renew their memberships and get a paper ballot from Mike Cory.
George Grantham talked about upcoming shows: WA State Fair in Puyallup &
the Tri Cities Orchid Society Show.
Abby made suggestions on how we could help with our own upcoming
show and asked us to sign up on the sheets.
At the June meeting, Mike Pearson announced a new Award: the AOS
Certificate of Appreciation for Outstanding Service & Commitment to the
NWOS. Two of these certificates were presented for the special work done
for the NW Flower & Garden Show, one to Allan Kaas and the other to Joe
Grienauer. Joe was not present to receive his award so Mike and
Abigail presented it to him at the September meeting.
Agigail spoke about the new
AOS judging center in Spokane which will meet on Oct. 28th. See
In order to vote on the
Bylaws which were recommended by the Board we needed 50 members present.
But only 32 members were in attendance so we suspended the bylaws. We
were then able to vote on the bylaws changes by a majority of members
present. The Bylaws changes were approved. At the end of the meeting we re-instated
the bylaws. Mike Cory explained
the new membership dues structure and timing.
