Tree Aeonium

Tree aeonium (Aeonium arboreum) is an evergreen succulent subshrub with woody stems ending in fleshy, bright green rosettes. It adds a sculptural outline to dry-climate beds and containers; mature plants produce large clusters of small yellow flowers, generally in winter or spring depending on conditions. ## Landscape Use Use it as a specimen accent, in a mass planting, or as a low hedge in a mild, frost-free setting. Its rosettes and branching stems provide form and texture among lower succulents or contrasting foliage. In South Australia, the Botanic Gardens and State Herbarium’s [Plant Selector](https://plantselector.botanicgardens.sa.gov.au/Plants/Details/814) lists it for ornamental mass planting and hedging, while warning that vegetative spread can make it invasive near conservation parks and coastal reserves; that warning is regional, so check local guidance. ## Growing Conditions The [Royal Horticultural Society](https://www.rhs.org.uk/plants/498/aeonium-arboreum/details) describes a bushy plant 1–1.5 metres tall and wide, with a sheltered, sunny position and sharply drained loam or sand. The South Australian Botanic Gardens profile reports a 1–1.5 metre spread, yellow flowers in winter and spring, and minimal supplementary watering. Give it free-draining soil and water moderately while actively growing; avoid keeping the mix wet, especially during hot-weather dormancy. Protect it from frost or grow it in a movable container where winters are cold. ## Maintenance The RHS notes that routine pruning is not required. Remove dead lower leaves only when needed for appearance, and avoid overwatering during hot periods when growth slows.
