Phal. amboinensis 'Krull's Yellow King'
 

So my yellow king is growing like crazy all of a sudden (well, for the past month or so). It's currently growing a new leaf, three new stem roots, new roots in the medium, a new flower spike and two of its existing flower spikes are producing flower buds. It's one of my most ambitious phals that's for sure :)

Oh yass! Amboinensis is one of the best Phal species. Get a 'Nicole' and you'll have both colors!
