Question about Leptotes bicolor bud sheaths

[whygreenberg]

Hi all... My Leptotes bicolor has been putting out little nubbiny buddy sheaths from the bases of leaves, where the leaves are grooved. But they've been doing this for a while now, some since January. They seem to gradually get bigger and more plump, but still are just at the leaf bases.

I guess my questions are: is this 'chid generally slow to put out buds? If the nubbins sheath over, does that mean they won't bloom? What should I be looking for to show progress? Probably, I just need to be more patient. But I don't really have any idea of what to expect in terms of the Leptotes habits.

Any thoughts or advice much appreciated!
