This is a young plant of Phalaenopsis equestris orange. The older leaf got yellow, but I hope it is normal because all other leaves look healthy an happy:
Thre is also a spike, that started under the leaf on the left:
I am really looking forward to see the flowers when/if it will decide to bloom.
I have this idea to collect all varieties of equestris, so far I have blue and orange. There is also alba that came gorgeous and healthy but lost all the roots under my care :( I am trying to save it, but it doesn't look promising enough to log it here yet.
