Origin:
A mutation of Aeonium ‘Green Cashmere’.
Known names:
‘Gold Emerald’ — the most widely used name in Europe —, ‘Gold Jade’, ‘Golden Jade’, ‘Golden Jade Variegated’, 金丝翡翠 (Jīnsī Fěicuì) and 金絲翡翠.
‘Golden Jade’ is linguistically closer to the Chinese name than ‘Gold Emerald’.
Creation date / Breeder:
A Chinese mutation by an unknown breeder, which appeared no later than 2021. The earliest dated mention found is from December 5, 2021; its cultivation is confirmed by a Chinese video dated February 24, 2022.
Botanical description:
Aeonium ‘Gold Emerald’ is a shrubby variegated Aeonium derived from a mutation of Aeonium ‘Green Cashmere’. It belongs to a group of cultivars whose variegation and coloration remain generally stable throughout the seasons.
Its foliage generally consists of a broad green central band, whose intensity varies with growing conditions, framed by two pale yellow to cream lateral bands. These marginal zones may nevertheless change and display partial regreening, sometimes quite markedly.
The leaves form compact to semi-open rosettes borne on the branching stems typical of shrubby Aeoniums. As with many variegated cultivars, growth is influenced by light: stronger exposure tends to enhance the contrasts, while lower light levels may soften the variegation.
One of the most interesting characteristics of ‘Gold Emerald’ is the ability of its yellow or cream lateral zones to temporarily turn green again. This phenomenon can be pronounced enough to alter the visual balance of the leaf.
This behavior is particularly useful for identification, as it appears less pronounced — or even absent — in certain similar cultivars such as ‘Yanning’ and ‘Maybach’. It suggests partial instability in the distribution of chlorophyll pigments, probably influenced by light and growth vigor.
How can ‘Gold Emerald’, ‘Yanning’, ‘Maybach’ and ‘Green Medusa’ be distinguished?
‘Gold Emerald’ is often confused with several Aeoniums from related lineages, particularly ‘Yanning’, ‘Maybach’ and ‘Green Medusa’. Reliable identification generally requires several characteristics to be considered together.
One of the most useful clues is the tendency of the margins to turn green temporarily in ‘Gold Emerald’, as shown in the photograph below. This does not occur in ‘Yanning’ or ‘Maybach’.
The comparison with ‘Green Medusa’ is based mainly on the color palette: ‘Gold Emerald’ generally displays golden yellow to bright, sometimes almost fluorescent green tones, whereas ‘Green Medusa’ develops much paler, sometimes nearly white zones.
This difference in pigment saturation is an important visual criterion, although it varies according to growing conditions.

Growing and behavior
According to available observations, ‘Gold Emerald’ displays relatively vigorous growth and a good capacity for branching, making it an interesting ornamental cultivar.
No particular sensitivity has been reported to date. Like most variegated Aeoniums, it appreciates:
- a very well-draining substrate,
- a bright exposure without excessively scorching sun,
The variegation and color intensity may vary with light, temperature and water stress. Insufficient light can reduce the contrasts, while strong light tends to intensify the yellow and golden tones.
