Aloe nobilis are small and green right now but when they get bigger they will form a mounding field of rusty dark green toothy aloes that are covered in orange flowers in the winter.
South African, some would say this is not a species at all but a hybrid aloe. A hybrid? Between A. mitriformis x A. brevifolia? Is that so? I don’t know. My South African Aloe book doesn’t mention the plant at all, so that might indicate its a hybrid.
