Bifrenaria harrisoniae (yellow color forma)

[Frdemetr]

This is the first harrisoniae of the season (usualy the first one to bloom is the s/a, that is in spike now). Unlike the pink harrisoniae flowers, that become more yellow as they become older, this one is 'yellow' all time (I phtographed the flowers with only two days). Deliciously perfumed (as all harrisoniaes), the fragrance is strong in the morning.

What a beauty you have there. GREAT GROWING!

Oooooo...I'm dying to try one of these guys!

What conditions do you grow yours in, Frederico?

Your Harrisoniae is great. I love this orchid. I have one here in Australia, and mine is growing outside all year round under some big pine trees with dappled light and it flowers for me. I don't have much time for my addictive hobby so when something works for me without out too much stress, I am excited. The perfume is beautiful. Are yours growing outside? You probably have perfect conditions for them in Brazil.

Hi Susanne and Sue!

Section Harrisoniae Bifrenarias (harrisoniae, tyrianthina and inodora - and the amazing rarity verboonenii) are usualy very easy to grow, they love lots of light (growing them outside - if possible - is a good idea!), almost direct sun, and a easy-draining media (inodora is the only epiphytic; harrisoniae is facultatively rupiculous or epiphytic; tyrianthina and verboonenii are strictly rupiculous). In the nature they live at elevations betwen 800-1200 meters, with hot and dry days and cool/cold and wet nights. A great day/night temps difference (in the winter) induces blooming (in spring/summer). They are very resistant to insects and diseases (except slugs & snails and brown dots in the leaves - fungus). I hope you enjoy to grow more Bifras!

Thanks Frederico...

I'm just worried about those cool/cold nights

We only have them here for a few weeks during winter and that's it

Awesome bloom Frederico. I acquired one in May/08, hope I get blooms like yours.

There is an article in press in the Orchid Digest covering all the color forms of Bifrenaria harrisoniae.

Susanne,

I mean "cool" and "cold" in terms of brazilian weather! Cool ~18-12°C and cold ~8-10ºC! I guess in Florida these temps are possible! Perhaps the altitude is the problem ? Here, only above 700m we have a large day/night temps difference (>10ºC) in the winter.

They need an absolute winter rest, right? I purchased one last spring and I'm trying hard to keep it thriving for next blooming season.
