To illustrate: here's a shrubby Aeonium hybrid in the landscape in full summer mode. The rosettes are smaller (fewer leaves, shorter leaves) and closed up on themselves. There's nothing wrong with the plant, it just hasn't rained properly since March and it usually doesn't rain until October at the earliest. It will rebound and green up after that point.
If you look at the two red arrows I put in there, you can see "waists" in the stem where it narrows and the leaves are packed much more tightly together (judging by the scars they leave behind) along the stem. That is summer stem. The distance between the two arrows is one year's worth of stem growth.
Compare and contrast that image to this one (same hybrid, just growing on the patio) in mid fall.
