Welcome

Welcome to the Sacramento Orchid Society’s website. We hope you find the information here useful. We’ve made some changes recently so please explore the site thoroughly. You can check out our events page for information on upcoming events.

About the Sacramento Orchid Society

The Sacramento Orchid Society was founded in 1947 as an educational organization dedicated to providing information on the cultivation of orchids to the greater Sacramento community.

Members and non-members alike are welcome at our FREE Monthly Meetings that feature expert speakers from around the world, our members Show & Tell which is like a mini orchid show each month, opportunities to buy and sell plants, and a delightful measure of fellowship and good times. You will also find out about upcoming events and opportunities to support our society.

The Society's very active membership grows an almost unimaginable number of orchid species and hybrids on windowsills, patios, in yards, under lights, and in greenhouses.

Orchid Of The Month

October 2026

Phalaenopsis gigantea var alba
Expectations and Reality By Daniel Pfarr

I first saw Phalaenopsis gigantea variety alba (sometimes called variety decolorate) in lectures at International Phalaenopsis Alliance meetings about ten years ago. I knew I had to have one. If I only ever got to see it myself and that was it, I was still willing to sacrifice eating, I would run my car on fumes, and if there was a black market for toes, I might’ve cut off a toe to get a gigantea alba. Maybe.

In 2018 a vendor from Taiwan was speaking at an IPA meeting and had seedlings of a selfing of Phalaenopsis gigantea variety alba ‘Tai Wei’ growing in 3-inch nursery pots for $100. It took an additional 8 years for that to flower!

Between that first seedling and the time it took to flower, availability increased and I was able to purchase more. Hopefully they are going to flower soon!

With the increased supply, more people acquired and began breeding them. The appeal of gigantea breeding is hopefully easy to see: round flowers with exotic spotting and a waxy sheen. Coupling these characteristics with breeding hybrids that are in the yellow and green spectrum doesn’t yield great results, likely producing just normally colored gigantea.

For me, initial positive results weren’t immediately realized. Most of the unbloomed seedlings I was excited to buy turned out not a prized alba but muddied reds. I had bought some gigantea primary hybrids using tetraspis and amboiensis var alba. These two primary hybrids, Gentleman Jack and David Lim, respectively are great hybrids in their own right but I wanted some new novel examples in order to skip ahead in my breeding plan.

Pictured above is what all the seedlings of the David Lim looked like. It shouldn’t be any surprise that they weren’t alba. Even with a simpler genotype the progeny did not bloom as expected. I suspect that there is more than a single allele controlling pigmentation. Often there are clones available of gigantea alba hybrids. Clones give me what I want instead of having to grow out a population of seedlings and then looking for the special alba ones; the process I was going through hoping to flower something exceptional.

This summer while touring Taiwan’s Phalaenopsis greenhouses, I finally found a clone of David Lim alba named ‘F-10’ at Lioulin Orchids.

I brought a couple home and will be excitedly watching them for a long time as they slowly develop their spikes and bloom for me this winter.

The hybrids of gigantea can be as exceptional as the species when grown into specimen-sized plants. The inflorescences are persistent and produce flowers terminally annually while growing additional inflorescence. They also have stately leaves true to their name. Below are some specimens growing in Taiwan. Some of the leaves were about 1 meter in length!


I’m excited to have some confirmed examples of gigantea type Phals that are in the yellow spectrum so I can continue breeding without shrugging my shoulders for years before they flower.
