Hello,
I potted a keiki from a no ID phal a few months ago, a grocery store purchase. When should I expect the keiki to put out a flower spike? Years? Months?
Not predictable... Among the factors, how well developed were the roots when you potted it? How big are the leaves? How healthy, overall, is it? Then, when did the mother plant bloom? That will possibly be an indication of when that particular hybrid blooms but not necessarily (since the grower could also manipulate bloom time). So you need to keep it healthy and growing, it will bloom when it's ready, if it is getting its cultural needs met.
