There's no a variety called Cajun Sun. This one is Cajun Sunrise. There are two cvs registered with this name. In this case this variety is a Dupont cv,

The IHS site does show a Cajun Sun cultivar in addition to the two Cajun Sunrise cultivars. It looks suspicious because the registration date is the same as the one for the Dupont Cajun Sunrise, but the two photos are quite different. Cajun Sun is a double orange and Cajun Sunrise is a single yellow.

The team Dupont-Gerlich doesn't registered their varieties so, from time to time, some of us do it. That's why you have found the same date for both cvs. I've talked with the person who registered Cajun Sun, as I knew it doesn't exist, and we've decided to remove it from the register. So you won't find it now.
