Looking nice. What your culture? I got these small seeding compare to yours mine seems like having years to go. Any fragrant? Dose it smell anythings like Miltoniopsis?
As it is a native plant, its cultivation is very easy in my conditions; actually Milt flavescens does not like the substrate, preferring to grow around the pot, and not in it! You can mount it on bark or on coconut fiber "stick" or slab. The smell is soft and sweet, but I guess the perfume is not like Miltoniopsis
