When will my Paph bloom again?
You have to be patient when the plant you purchased in flower is done flowering, because it needs to mature another growth before it can flower again, unless it is a sequential bloomer from the section Cochlopetalum . Your plant will also take a bit of time to adjust to your growing conditions, and your potting medium if you choose to repot it after flowering (which is always a good idea). Many of the species and hybrids are somewhat seasonal in their flowering; others will flower pretty much any time of year when they mature a growth. Still others can bloom more than once a year once they become larger, multigrowth plants.
Will it bloom again from the same growth?
You will get only one inflorescence per growth; you need to mature another growth to get another inflorescence. There have been rare recorded instances of some plants pushing up 2 inflorescences from the same growth. The exception to this rule is plants from section Cochlopetalum, which will give you flowers sequentially on the same inflorescence for many months.
