Brassia Edvah Loo 'Nishida' x Miltonia clowesii, a hybrid that grows very well but rarely blooms in my garden

The flowers of this orchid have been surprisingly variable, sometimes they have long Brassia like floral segments and sometimes they don't.  It grows very well and can tolerate a wide range of sun exposures.  I have grown it in shade and in places where it gets hours of full sun.  It has bloomed in both places the flowers were more Brassia like when grown shady and favored the clowesii parent when grown in the sun.

Brassia Edvah Loo 'Nishida' specimen plant

All the inflorescences would orient in the direction of the strongest ligh, this caused some to overlap which caused the flowers to become crowded due to their large size.

This orchid produces huge flowers well over one foot tall.  The inflorescences are massive and the fragrance is delightful and powerful.  I used to have this huge specimen which produced amazing displays of flowers when it bloomed.  When it got so large it was difficult to move I decided to divide it.   I cut it in seven pieces and to my horror six of the pieces started dying from rot.  Only a tiny piece, that I had left out and had not potted because it had few roots, survived.  After four years of precarious growth that piece bloomed for the first time this July.  Hopefully it will grow well enough to reclaim its past glory.

Previous to that awful loss of plants, this orchid had proved to be easy to culture, a vigorous grower and a reliable bloomer.  It is not clear why the pieces got rot.   This orchid used to be very common, however it has been some years since I have seen plants of this hybrid shown anywhere.  It would be interesting to know if others have had the same experience I had with this orchid.  I remember seeing some pretty impressive plants shown in orchid group meetings.
