Plumeria flowers are most fragrant at night in order to lure sphinx moths to pollinate them. The flowers have no nectar, and simply dupe the moths to inadvertently pollinate them by transferring pollen from flower to flower in their effort sapping fruitless search for nectar. This Plumeria is a very heavy flowerer that blooms with ease producing dozens of flowers during the spring and summer months. Flowers are 3.5 - 4 inch in size and there are normally lots of them. Easy to germinate and care for. Growing advice provided on the website.
