Hot Growers

The splendidum I am growing in lava rock; it is a very small one, no blooms yet, but it is considered warm to hot growing. The ampliatum I am growing as a mounted plant, which it seems to like, it is considered hot growing.

I'm really leaning towards the mule-ears at this point. There are some monsters and some reasonably sized ones too. It seems like finding them for sale is the toughest part of their culture!

Small alliance Sigmatostalix? My picturatissima is tolerant of all sorts of abuse and neglect and is suppose to be a warm to hot grower.

From the alliance. I'll check out the Sig. picturatissima. Thanks for the tip!

I've grown a couple of mule ear oncidiums here in Florida and they seem to tolerate the heat pretty well. They've been reclassified as trichocentrum. I've never seen a vendor who specializes in them but you can find them for sale from time to time. Most of them are big plants with large leaves but there's also some very interesting trichocentrum with pencil thin leaves, like trichocentrum jonesianum. Most trichocentrum like to dry quickly and do well mounted or in fast drying mix.

Here's a picture of one of my trichocentrums which unfortunately died although I had it for several years.
