Bifrenaria inodora alba
 

This year my inodora alba has flowers all around the pot, a show of color (or better, no color!) and perfume!

I love the green coloring on the petals. :biggrin:

I love low blooming orchids like this one. These blooms are fantastic.

Fantastic, Frederico! Does this species need a dry winter rest in order to get it to bloom?

It's gorgeous!

Hi Steve,

"Large flowers" Bifrenarias (harrisoniae, tyrianthina, inodora etc) actualy don't need a winter rest (ie, you don't need watering less), but they are demanding in terms of day/night temperature difference in the winter, otherwise they don't bloom in the spring. Bifrenarias live in the "Campos Rupestres de Altitude", or medium/high altitude savannah (800 - 1500m) in the nature, with large day/night temps difference.
I guess at least 10°C day/night difference in half of the winter days are enough to induce blooming; fortunately I live at 800m above sea level and I have these conditions!

Thanks, Frederico, for your response. So what would you say are the average nighttime temperatures that the bifrenarias receive in your location?

Steve,

In the winter the temps are between 10 and 22°C, in average about 15°C; in the summer 18-30°C, in average about 22°C. Sometimes "extreme" temps occur (5°C in the winter or 35°C in the summer), but fortunately it's uncommon!

Thanks again, Frederico. Although I have two plants of Bifrenaria harrisoniae, I don't have inodora. The two harrisoniaes bloom for me every winter, so perhaps I would be successful with an inodora also.

They are gorgeous blooms! I love the coloring. I have the harrisoniae and give it a winter rest. I did not know that they don't need one. One thing about orchid growing....when you think you have a handle on a type orchid, you soon realize you really don't. :rofl:
