Decadence is one of the most celebrated iris of the last twenty years or so and for good reason. Big beautiful flowers, strong stalks and great growth. Absolutely nothing not to like.

I cannot speak for other areas within Zone 8, but here in coastal SC (north coastal), this flower is an excellent grower, very good increaser. The standards in the evening sun have an orange/melonish glow. Looks-wise, Decadence is a real showstopper.
