Still at the Los Angeles Arboretum. Many of the plants had identifying signs, but this one didn't. I did some Google image searches & I believe this is an aloe arborescens, but I'm not absolutely sure. When I've posted photos in the past & guessed at a species of plant or bird, I think I've been wrong more often than right, so if there are any botanists out there who want to correct me, please go right ahead. Assuming I'm correct, this is what Wikipedia has to say about aloe arborescens: "Aloe arborescens is a large multi-headed sprawling succulent, its specific name indicating that it sometimes reaches tree size. Typical height for this species 2–3 metres (6.6–9.8 ft) high. Its leaves are succulent and are green with a slight blue tint. Its leaves are armed with small spikes along its edges and are arranged in rosettes situated at the end of branches. Flowers are arranged in a type of inflorescence called a raceme. The racemes are not branched but two to several can sprout from each rosette. Flowers are cylindrical in shape and are a vibrant red/orange color. Aloe arborescens is endemic to the south eastern part of Southern Africa. Specifically, this range includes the countries of South Africa, Malawi, Mozambique and Zimbabwe. It has the third largest distribution amongst the aloe genus. Although Aloe arborescens has adapted to many different habitats, its natural habitat usually consists of mountainous areas including rocky outcrops and exposed ridges. Its common name krantz aloe refers to the Afrikaans word 'krantz', which means a rocky cliff. Its habitat can vary and is one of only a few species of aloe that is found growing from sea level up to the tops of mountains." Please zoom.
