It's late winter here in Sydney, which is very 'spring-ish'. I noticed a couple of flower heads developing on my Neps yesterday (ventricosa and truncata), which is about a month or more earlier than normal for those species. There's no sign yet on any of my other mature plants, aristo for example often flowers in late summer/autumn.
Does anyone notice that particular species flower at the same time every year, or at different times during the growing season? Are they once a year bloomers, or do they have several flushes?
