My baptisma bloom lasted just under 3 weeks, it blooms up the stalk. By the end of the bloom you will still get random single blooms that pop off the stem. I don't know if they are fragrant..always forget to sniff new blooms..the color takes my breath away. I've just started a circle of seed in a pot that I'll put in a sheltered spot and hopefully they will return next year. I'll make sure that they are mulched this winter. They are a bi-annual so always keep seed.
