Aloidendron ‘Rex’ is a hybrid between Aloidendron barberae and Aloidendron dichotomum, with A. dichotomum as the seed parent. It was developed in Swellendam, in the Western Cape of South Africa. It is the same parentage as ‘Hercules’, but a different cross, made independently and with a different seed parent.
Description
‘Rex’ forms a tree with a grey trunk. The leaves are more slender than those of ‘Hercules’, grey-green, with pink teeth along the margins. It grows faster than pure Aloidendron dichotomum, which is one of the slowest tree aloes. It inherits the quiver tree’s elegant, fairly light outline rather than the massive crown of A. barberae.
Cultivation
Treat it like its parents: full sun, a very well-drained mineral substrate and moderate watering in the growing season, dry in winter. As with the other A. barberae hybrids, overwatering produces soft, heavy growth. Frost tolerance has not been documented precisely for this cultivar; assume it is comparable to ‘Hercules’ (see that page) and protect young plants from frost and prolonged winter wet.
What is not documented
We have not found published information on the breeder, the year of the cross, the mature size or a measured cold-hardiness limit. This page will be completed when reliable sources are available.
