I thought I bought Minature Phals...

[MattWoelfsen]

Phalaenopsis in my opinion do get large even if described as being a mini. As you have experienced, I have several mini Phals that are not as big as standard but they do take up a lot space. However there is a variety, bred in Japan, known as Sederia japonica, now renamed Phalenopsis japonica that are truly miniature.

I have a Sederia japonica called Min-maru that is no larger than three inches from leaf tip across to the next leap tip. It is very hard for me to grow--this is my fourth attempt to grow this variety. It might do well in a terrarium. They are not inexpensive. I bought this Sederia two months ago for US$34.79 on eBay from Seed Engei. They also have a website where they sell directly to you. They do not have Sederia japonica in stock for sale on the website. If you launch their website you will see Neofinetia falcata plants, these are miniature Vanda. They also sell Dendrobium moniliforme--miniature Dendrobium.

There is another vendor specializing in Japanese provenance orchids: New World Orchids. They sell Neofinetia falcata, Sederia japonica, Dendrobium moniliforme. They also sell Sophronitis Cattleya orchids from Brasil via Japan. These are miniature Cattleya.

If you want to expand your experience with other kinds of miniature orchids besides Phalaenopsis, I would start your journey by going to these two websites.
