http://www.orchidboard.com/community...data/515/O.jpgrchid culture books often state that Dendrobium kingianum (recently re-classified as Thelychiton kingianum) is an easy orchid for beginners. Many orchid growers would disagree. Any orchid is easy if given the proper conditions, but the proper conditions for D. kingianum are not our typical household or greenhouse conditions.
Dendrobium kingianum was my very first orchid, given to me in 1988 by a local orchid grower. This grower never got little from the plant in terms of flowers but did get plenty of keikeis. So a few keikeis were passed to me. At the time I was having great success with African Violets and this gardening friend said I should have no problems growing orchids. And thus the addiction began!
My keikeis grew gang-busters and by the following fall the plant was in a 3.5" pot. I grew the plant in an unobstructed east window. http://www.orchidboard.com/community...numJan2006.JPG
The minimum winter temperature was about 60 F with days around 70 F. The fall and winter came and went, but no flowers. Not to worry, many orchids take a year or two to settle down and start blooming. The next fall, the plant, now in a 5" pot, produced 7 spikes! However, when the spikes were 2" long, the buds started to drop. In the end I had only 4 individual blooms. The flowers remained open for 2 months and were delightfully fragrant, smelling to me like Johnson?s Baby Powder.
I later read that in their native habitat of eastern Australia, this orchid blooms mid-winter after a cool, dry autumn season and during this rest they may actually be exposed to near freezing temperatures! So perhaps my growing area was too warm. The following late September I placed my plant in a sunny, west-facing basement window. My basement is unheated and is the area where I grow my cool-loving Cyclamen. The night temperature in that window was about 50 F with days under 65 F. At this stage I only watered my plant every 2-3 weeks. By mid-December the night temperatures were down to 38 F and the days were only 50 F. I lost 3 leaves to frost where the leaves were touching the glass! However, at this stage, the plant had the beginnings of 15 spikes! I then brought the plant back upstairs and placed it an east window where the night temperatures were about 55 F and days about 65 F. Regular weekly watering resumed. The spikes rapidly elongated and by late January I had a total of 54 blossoms. The fragrance filled the entire living room each afternoon.

Really cool story! Great advice on growing this species! That plant of yours is amazing, and I can't fathom 29 spikes!!!!!! Congrats!

Great story, I like how you depict the passing of the seasons and how this effects the growth and flowering of the plant. I can tell that you're a gardener.;)

Hey Tod,
An EXCELLENT article. Your image simply
floors the reader, especially those who know and have tried this section of Dendros!!

Great to Aussie dendrobs on the other side of the world

Well done, (from down under NZ)
To get an orchid and to get it to flower provides great personal satisfaction.

You should try putting a kiki on to a tree in your garden or wooden raft they can make a nice center piece.
I have quite a collection of Dendrobiums and there are now some fantastic flowers with amazing perfumes being hybridized these flowers are also becoming long lasting. (over 8 weeks)
Some are providing phalaenopsis type flowers and others with star flowers over 3" in size.
I like them because you can get a flowering plant in a 3" pot suitable for on the table if you so desire.

I have a Dendrobium Suffusion which is 24' in Dia. and provides about 100 plus flower spikes every year

Yes, cool is key to flower production! I leave my D. kingianum out until heavy freezing temps occur. Mine has grown and flowered well! I water all spring, summer, fall...water it enough to dampen it...all under basement fluorescents during winter. Then, they go outside in early spring.
