That is not Aeonium arboreum... but Aeonium davidbramwellii 'Sunburst'.

I'm assuming it's not just this photo that you are referring to, but rather the whole entry? I've done some research, and have come to the conclusion that since 'Sunburst' is a hybrid and there is apparently some confusion as to which species are involved, that we should remove the specific epithet completely.

In Rudolf Schulz's book 'Aeonium in Habitat and Cultivation' he refers to A. 'Sunburst' in numerous places and had many photos that all look like the photos in this entry to some degree. There appears to be lots of variability with this cultivar. He doesn't attach a specific epithet to the photos , but refers to them as A. 'Sunburst'.

This is what he says about 'Sunburst', which verifies the specific confusion surrounding this cultivar.

Quoting:
A more recent variegated cultivar is A. 'Sunburst'. It has been incorrectly called A. decorum 'Sunburst' (and sometimes A. percarneum 'Sunburst'), but the reversion of this plant is very much like A. davidbramwellii, with rosettes growing up to 400 mm in diameter, well beyond anything that A. decorum could manage. A. 'Sunburst' reverts to a form with streaked variegation towards the middle of the leaf, which sometimes goes under the name A. 'Sun Beam' or 'Starburst', but also goes under other nursery-created names.


He states that A. davidbramwellii is variable and has no distinctly defining characteristics, and is a thick stemmed, shrubby species with leaves less than four times longer than they are wide.

His description of A. arboreum is that it has very thin leaves compared to all other species, and is a shrubby, thick stemmed species with leaves more than four times longer than wide.

It's very hard to tell from photos, but most of the photos in the entry appear to have leaves that are more than four times longer than wide, including the one on this thread, which would point more towards A. arboreum than A. davidbramwellii, not?

This site lists it as just Aeonium 'Sunburst' http://www.plantsafari.com/Catalog/Detail/00037.html

This site states that there is some confusion as to the species and should be known as Aeonium 'Sunburst'. http://www.smgrowers.com/products/plants/plantdisplay.asp?plant_id=2034

Do you have any other resources that I can check? Or any thoughts on removing the specific epithet completely?

I will bet you the leaf edges of your plant are firm and have dinky little reddish teeth. And the leaves themselves are thick, firm and just very slightly rough to the surface. Aeonium arboreum also comes as a variegated form but the rosettes are smaller, only two colors, soft, smooth and have tiny whitish teeth along the edges. That is not an Aeonium arboreum hybrid. You may have to have the two side by side to appreciate the differences, but they are not that much alike once you see and feel them in person. I have no idea if the Aeonium arboreum hybrids are also called Sunburst, but the classic 'Sunburst' is Aeonium davidbramwellii... it is super common and sold about everywhere... Aeonium arboreum variegated is common, too, but much less so for a variety of reasons- less colorful, less hardy to hot, dry sun, and smaller, less spectacular rosettes.

I just happened to be at a local nursery today and saw an Aeonium arboreum variegated for sale, so got a photo of it.

If you look at your Aeonium, and then this one, you will see some differences.

Sorry Geoff, I think you misunderstood me. I don't have this plant. I'm just trying to figure out how to correct the problem with the species and/or misplaced photos. All I have to go on is online references and Rudolf Schulz's book.

oh sorry... the first plant, as I said, was Aeonium davidbramwellii Sunburst, not an Aeonium arboreum species... sorry for the misunderstanding
