Zygopetalum Big Red, 4/16

Zygopetalum Big Red, 4/16

Zygopetalums are usually heavily scented, I was delighted to find this one wasn’t.

Water enough to keep the roots from drying but don’t let it sit in water.

Moderate light, no direct sun, but bright indirect sun.

Zygon: means yoked petal
Native to South American rain forests about half way up the mountains.

This is a brand new acquisition from the Houston Orchid Show. So details here may change.

I potted this semi-hydro ( glass pot, clay pellets, about an inch of water well below the root level ) I’ve had fantastic luck with the other orchids potted this way.

Like phalaenopsis these should not dry completely out, let them get slightly drier in the winter so they don’t rot. Like all orchids they need a good dose of fertilizer each watering.

Early searches turn up little care information, light shade, warm to hot temperatures. I’m going to treat it like a phalaenopsis and see how it does.

Fragrant at night, spring bloomer, self fertilizing, typically grown in a basket.

The leaves should get much longer as it grows 15″-16″ in length, the flower stem to about half that length. Th flowers grow from the base of the plant.

Central American native first described in 1840. It is currently a protected species. Grows in trees in wet forest ~ 350′-2000′

Like many house plants, these were no where, then all of a sudden everywhere. These just arrived a few weeks ago, so I may change this as I have some time to experiment with them.

These arrived at about 18″, the stalks will reach 36″ when it is full grown. There are no flowers or spikes but they are large enough to bloom. It may be next year before I see flowers. You’ll need a drafty windowsill to give the the 15′ temperature drop they need to go into blooming mode.

These are from Papa New Guinea, and like most island tropicals they grow in a very narrow temperature range, 70’F-80’F. I’d keep them inside, even in the summer.

I recently shifted all my orchids to a semi-hydro ( clay pellets ), they’ve all done extremely well so these are planted that way as well. They are in 6″ glass cubes, the bottom third is pellets, the plant roots are spread around the top 2/3 and clay pellets have been worked in between and around the roots. They were extremely root bound when they arrived in their 4″ pots.

Water and fertilize less in the winter, this is supposed to help encourage blooming.

I’ve read they need quite a bit more sunlight than other dendrobiums and most other orchids. I’ve placed them in a southwest facing window with very little shading ( in Houston ). We’ll see how it goes. They’ve survived the first few weeks but it’s been cloudy. This window is bright enough to burn other orchid plants but not Venus Fly traps or other carnivorous swamp plants.

These turned out to bloom as easily as other dendrobiums. Put them on a window sill so they’ll get the winter temperature drop and give them just a tiny bit more light than other dendrobiums. They will burn if given too much light. The flowers are heavily scented.
