I grow that Zygo, Fiat. In my garden, it usually makes its blooms in mid Spring. I have been rather remiss on this one, if I remember to fertilize then it gets some, but it still stays on as long as it gets watering as needed. I do hide it indoors though by our south facing window during winter. Come Spring time, when overnight temps are stably above 50F, then I can put it back along with my other oncidiums to my grow camp outdoors. I treat it like my other oncidiums, loves frequent watering in my dry area and good air circulation. It gets some shade from our city trees here, so it endures the triple digit heat, but just have to step up watering during our long dry season.
Just got to adjust watering as season changes, more water during the hot, dry season, and a bit less with some interval during the colder months. It does have a lovely lilac-like scent, and have you seen the little tattoo imprint at the back of the lip..so pretty
Just adding, I also notice it starts to make new pseudobulbs in my area around Fall season, when temps cool down from our onerous heat wave days, and it will continue on to Spring to make a new flower spike afterwards.
