This aloe is named after Pretoria but occurs in a much larger area from northern Gauteng, Limpopo, Mpumalanga, Swaziland and Zimbabwe. One would need to protect these Aloes during the winter if they are planted in frosty gardens. The flower spike is exceptionally long which makes it very distinctive. The flowers are pencil shaped and are bright red as are the tips of the leaves during the winter. The word Aloe comes from the Greek and refers to the bitter leaf gel.
