flower-of-an-hour
Hibiscus trionumAlso known as Bladder Hibiscus, Bladder Ketmia, Venice Mallow, Puarangi
Flower-of-an-hour earned its moniker from fleeting blooms that unfurl in early morning sunshine and collapse by midday. Cream to pale yellow petals showcase a dramatic deep burgundy center surrounding a prominent central stamen column. Following pollination, the calyx inflates into a distinctive paper-like bladder that protects the maturing seeds as they dry.
