A tricky plant

Frangipani is very popular around here, and grows well in warm climates. For weeks now, the strong perfume of its flowers has been hanging in the air. Wikipedia says they are most fragrant at night, to attract moths to pollinate them. The tricky bit is that the flowers yield no nectar. The moths inadvertently pollinate them by transferring pollen from flower to flower in their fruitless search for nectar. Nature can be very cruel!
