Oncidium Midas 'Willow Pond'

Oncidium Midas 'Willow Pond'
This cheery yellow oncidium is actually one of the older hybrids I've yet written about.  Oncidium Midas was registered in 1940, as a cross between Oncidium Ascania and Oncidium Reve d'Or.  The clone 'Willow Pond' has earned the AM/AOS distinction.  This oncidium resembles the tolumnia orchids--the small, compact plant body produces an abundance of flowers.


Oncidium Midas genealogy
If any of this genealogy tree looks familiar, that is because Oncidium Reve d'Or is also a significant contributor to the genealogy of Oncostele Wildcat. These are old crosses, and neither Oncidium Ascania, nor Oncidium Reve d'Or are popularly grown anymore.  But perhaps what is more curious is that Oncidium Midas, a cross made 76 years ago, is still widely available.


Another interesting find in this history tree is my new record for the oldest Oncidium cross ever.  Take a look at Oncidium Excellens--it was registered in 1891!

Back to Oncidium Midas. There are 5 Oncidium species which went into the creation of this cross: luteopurpureum, nobile, alexandre, spectatissimum, and harryanum.

Note: Oncidium alexandre is also commonly referred to as Oncidium crispum.

  1. There is a fundamental, almost fatal misunderstanding. The one labeled as "Oncidium" Midas is really Zeleminia Midas (Tolumnia Red Belt x Zelenkoa onusta), registered by W.W.G.Moir in 1974. There is Oncidium (syn. Odontoglossum) Midas, registered by Charlesworth Ltd. in 1940. Didn't it occur to you that the one in the top picture does not look anything like a traditional Odontoglossum hybrid??
