Something wonderful happened to the Oncidium though! For a few years now i suppose it is virus infected, as Oncidium varieties are really very susceptible to viruses. The flower buds just die and most of the time only 2-3 buds continue to open. So we just left it there, self supporting. Come this very dry season, when many fruit trees died and no annuals endured the very hot weather. Even with the leaves turning yellow due to extreme sun, this Oncidium flowered as it always does, but this time all the buds opened and spread its wonderful sweet scent especially in the mornings. It continued to be there for six (6) weeks now. Probably the virus become dormant due to the extreme heat. But that is only a speculation, as i am sure it is still there. I will see this rainy season if the flower buds will continue to abort.
If only i can share its scent here, it is really awesome, sweet and wonderful.
