This Phal is always flowering. Like its cornu-cervi parent, the flowers appear singly but the flowering can last for months or even years with one flower appearing just before the previous flower fades. This time i am able to take a good shot because the new flower happen to be at the right level for me to balance my camera and the flower is facing out so i don't have to shift the plant around to take a shot.
This is a very nice lamelligera from Joseph Wu. Bought it a few years back at the Garden Tech exhibition when it was held at the Hort Park. The flower has bold patches instead of lines and is much bigger.
