my coerulea is the smallest leaf span of all my vandas and ascocendas. it looks like a mini next to them. even my mokara is bigger, by a few inches, and it supposedly has some coerulea in it too. it also cannot take full sun whatsoever here, and listings always say they can. i got sunspots right off the bat though. there was a sliver of full sun coming over the trellis that nailed 2 leaves. i have since moved it to a more sheltered spot. it has grown some new roots and leaves, but seems to be a real slow grower for me. lucky you with a spike!! i'm so jealous.
