So sorry to hear that your "春蘭綠云被ko了".
Yes, great great care and attention are required in cultivating Chinese orchid, especially spring orchid. I still do not have the privilege to have 春蘭綠云.
春蘭綠云 is so attractive in flower colour and changing the petal sepal number - queen of Chinese spring orchid.
Keep up. All orchid is precious.
