The clump picture for Oakes does look to have the blackish stems, but it's odd they would list it at 30" in one spot but 12-20" at the top of the same page. They also have it as evergreen, although it is registered as semi-ev but of course foliage habit is not necessarily "fixed" (it was hybridized in Texas and a parent of 'Stella de Oro').
