Parentage : Sedum atratum x S. annuum

English translation of the French First Description :

The habit of the plant is similar to that of S. annuum, from which however it differs in the pale yellow petals with dark purple streaks and dense corymbs. It differs from S. atratum in its stems which are branched towards the upper part and in its much less dense corymbs though they are still much denser than in S. annuum.

 't Hart & Bleij (IHSP p.237, 2003) consider this name as of unresolved application.
