Like any other Phaius, this likes bright indirect light, or semi-shade if outdoors, and needs a fair amount of water. In nature, they grow along riverbanks.
These are only picky about one thing — water. Those of us who live in temperate climates can’t just plant them outside. So, they need water. Less than a pleuro, stan, or gongora, but you get the idea.
I really like this one. The blooms are pale yellow, with fuchsia spots. It probably would prefer life in a sunny greenhouse, but it does fine with a few hours worth of direct sun per day, indoors.
Chondorhynchas can be grown with Cochleanthes and related orchids — fairly wet and semi-shady. They will get accordion leaves if left too dry for too long. The blooms emerge from the base of the pseudobulb, if you can call it that, since they don’t really have pseudobulbs. A “spike” will emerge from the base of a leaf at the level of whatever medium you’re using with a single flower. Mine has one flower open, and another bud getting ready to open. The leaves are mostly lime green, and a bit yellowy because of the light levels it’s received, but it’s perfectly healthy. The flowers are unscented, but are frilly and cute.
Stelis morganii is smaller than argentata, both in leaf and bloom size, but the growth/bloom habit is similar. Many spikes emerge from the base of newly mature leaves. With morganii, the flowers are a very pale yellow, and with my horrible photography skills, difficult to photograph well enough to do it justice. If nothing else, this photo shows its growth and spiking habit.
As with any other Stelis, keep it shady and wet, and it will reward you.
Like all Stelises, this likes it wet and shady. Argentata is one of my favorites; the flowers are actually big enough to see, and I love the shade of red. As of now, four spikes are blooming, with another five on the way.
The general growing conditions for Stelises are similar to Masdevallias, except that they are more temperature tolerant at the upper end. The less fuss I have to put into keeping an orchid at just the right temperature, the better, so I’ve always had success with Stelises, while my luck with massies has been mixed. When open windows will do, I refuse to run the air conditioner just for a few plants.
This species blooms at a relatively small size for Renatheras. Like the rest of them, the spikes branch. This is a first bloom for this plant, with a spike that’s about a foot long that has two small branches. The flowers on my Renanthera citrata are just now opening, so I hope to have pictures of that one within a week. Here’s monachica:
I’ve had two of these for several years. They’re happy in part sun, part shade, with relatively minimal watering compared to its windowsill neighbors (Scaphosepalums, Cochleanthes, Restrepias, etc.). Each year, one or both bloom; for now, only one of them is blooming. Both are labeled Lockhartia Gold Speck x sib. I believe I got them from Exotic Orchids of Maui, although their tags don’t list the seller. They just look like the sort of tags EOoM uses.
This one bloomed with two spikes this year. It’s one of my most reliable miniature vanda intergenerics.
