Also from eBay, the 4 o’clock flower: The cheerful Mirabilis jalapa got the common name “Four O’Clocks” because the flowers open in late afternoon. They remain open until morning and on cloudy days, they may not close at all. Their other common name “Marvel of Peru” is probably because they are native to the topical areas of South America. Mirabilis means wonderful, in Latin. Since they open at night and are fragrant at these hours, their pollinators must be moths. I am not sure Sabah moths will recognise this flower; would be interesting to watch the flowers for a few hours at night.
