They will have flowers identical to the parent plant. Treat them as you would seedlings. I put them in a mix of fine fir bark and coconut fibre. Mine usually reach blooming size in one to two years. I only pot up the large ones.
Tiny ones tend to take for ever to develop.
Hope this helps. Hi Thanks for your reply regarding the new growths on top of my orchid. This orchid has had a terrible time this past year. All but two of its leaves have fallen off. It has some newer growth closer to the bottom, but I'd like to remove the stuff at top and repot it.
