Purchased from Le PARADIS DES ORCHIDÉES in Montreal in August 2016 as orange variety.
It took 4 years to bloom it and discover that it is actually alba.
Very slow grower for me but blooms in winter and does not require artificial light supplement to spike. It produced spike just on the windowsill. Probably drop in temperature helped.
Fragrant, smell is fresh and light, reminds grapefruit a bit.
