How long should I expect for my oncidiums to mature and bloom?

Part of the "when" answer lies in the parentage... some of these look to me like they might very well be ready to bloom in the next year or so. If the parents are relatively small, they can bloom (and be mature) on fairly small plants. One where I can clearly read the label, the Maclellanara (which isn't showing pseudobulbs yet) has a ways to go... those tend to get quite big - and need to do that before reaching blooming size. On the other hand, will be well worth the wait (capable of spikes 3 feet (1 m) or more) So the answer is, "It depends..." The ones with fully formed mature-looking pseudobulbs, likely can bloom on the next new growth.
