1. I tend to prefer species over hybrids, but depending on how things go, I will consider select hybrids.
2. I tend to purchase miniatures to medium sized plants due to space limitations. Occasionally the large or extra-large ones will make it into the collection.
3. I tend to like brightly colored or interestingly patterned flowers. I will not turn down plants with muted or neutral colored flowers, but it depends on whether I find them to my liking.
4. Flower size is irrelevant for the most part. Although I like to strike a balance in my collection so I'm not stuck with a huge selection of plants with tiny flowers.
5. I can grow a variety of plants from a variety of different temperature ranges, but I prefer plants that grow cool to intermediate or plants that range from cool to warm growing.
The exception being cold growers. I don't have the expertise nor the money to artificially create an environment for plants that grow above 2,600 m in tropical zones or alpine growers.
6. I prefer plants with a fragrance, but if they don't, it doesn't bother me.
However, in the orchid family, this is not a problem!
The majority of orchids are fragrant.
It just depends on whether they smell good or bad. Either one is fine for me. The ones that smell awful brings me some joy in that I like to see how people react when I either tell them the flowers stink or see their reaction when they actually smell it. (I know, I'm a bad, bad boy...
)
7. I can grow a variety of plants with different light tolerances, but I prefer plants that grow in shade to moderate indirect light.
8. Ease of culture. Basically, "Will they withstand me being away for a long period of time?" I try to limit the amount of plants that require constant vigilant care under my growing conditions.
An example of a group of orchids that may require a lot of attention, are species within the genus Lepanthes and Lepanthopsis.
9. This kinda ties into the ease of culture criteria...
I prefer epiphytes and lithophytes over terrestrials.
I find epiphytes and lithophytes to be less problematic than terrestrials for the most part.
Although, there may be a few terrestrials I do like and grow, epiphytes tend to be more rewarding for me.
There's also more literature about epiphytes than terrestrial orchids.
10. I like flowers that are uniquely shaped.
A couple of my favorite groups of orchids to grow tend to be Pleurothallids and species from the genus Bulbophyllum.
I will not turn my nose up on good old Cattleyas, Cymbidiums, or Phalaenopsis, though!
