Here are more aloe flowers:

Aloe divaricata

Aloe dorotheae- not a great flower, but overall look is good

Aloe dyeri

Aloe elgonica... getting a lot of red and pink flowers here...

for something slightly different... Aloe ellenbeckii

very rare in cultivation so far, Aloe eminens

Aloe esculenta

Aloe excelsa

another aloe excelsa (this plant fell over so got a good close up)

and here is my own Aloe excelsa plant's flowers

and to show that not all Aloe excelsas are red

Aloe ferox flowers come in all sorts of colors... if hybridized, which they do on their own readily

more normal Aloe ferox flowers

another nice Aloe ferox hybrid

and yet another Aloe ferox hybrid

And lastly, for now, Aloe vryheidensis hybrid (with ferox)
