It took me almost 4 years to flower my P. rothschildianum again. I was very lucky when I saw the sheath emerging in early autumn and had a look at the spike while growing almost every day. I thought 2 flowers would be o.k. for and window-sill grower and after the first flower blossomed out.....it happened while watering Wednesday one week ago. I was incaurtious, made an uncontrolled move with my right hand and dang......damaged one petal of the first flower. The are like glass direct when they are freshly blossomed out. Anyway, nevertheless I'm happy with these flowers and hope you will apologize the broken petal.
