Although Aloes are known for their large succulents leaves, a few species also attain really nice fat trunks. Aloe dichotoma grows very tall but will also form a very thick trunk that could be 1-2 meters wide. Aloe ramosissima is it's shorter sister species. A. ramosissima grows only to about four feet tall but develops an attractive fat trunk with thick tubers running in to the soil. It also has an attractive network of branches. Both species are from south African deserts, so they are sensitive to over watering and freezing temeratures.
