'Sunburst'(灿烂/花叶寒月夜)
Most probably a variegated cultivar of A. davidbramwellii.
最可能是Aeonium davidbramwellii的锦叶变种.
Incorrectly distributed by ISI as Aeonium decorum 'Sunburst'. Rudolf Schulz writes : "… 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" .
错误地被ISI作为Aeonium decorum 'Sunburst'.鲁道夫·舒尔茨写道:"......这种植物的退化植株非常像Aeonium davidbramwellii,莲座能够成长到400mm的直径,远远超出任何一株Aeonium decorum能够到达的大小.
染色体:2n =36

Aeonium davidbramwellii寒月夜,是硬叶系Aeonium中较有代表性的,种子发芽率较为高,抗性亦较好,并且随着季节轮转的变化非常大,有时很难看出它们是一个品种.
