this is a very variable South African species with, according to me, 3 distinct forms (only two official forms listed, though). The type form is a smaller, very glaucous, profusely suckering plant that has very short to no stems and rosettes about 6" in diameter (or a bit more). Then there are two larger, much less-apt to sucker forms... the grey, glaucous form seen in the top photo is a large almost tree-like Aloe with fine lines along the leaves and rarely suckers. Rosettes are about 12" to 16" in diameter and leaves tend to have reddish teeth along the margins. The other form is a green, non-glaucous form with is slow to form a stem and is about half way between the other two in terms of rosette diameter. It also has reddish teeth, but they do not stand out as well. Lines are present in these leaves, too, but not as clearly. Both the larger forms are lumped loosely under Aloe glauca var. spinosior (aka muricata).

Flowers are larger on these two larger forms but all Aloe glauca flowers are reddish to pale reddish in winter.

"profusely suckering" is right! I had already removed and rooted a dozen plants from this only a year ago. Not only has the plant doubled in size, there's a whole new batch of suckers in addition.

This is my alleged Aloe glauca - can anyone confirm ID? Not very glaucous, offsets but not profusely. About 15" across and has a short trunk.

This is also an extreme form of Aloe glauca found and named by Peter Brandham of Kew Gardens, in a South African garden centre in the 1980’s.

Hello Mickthecactus,
I believe this is not Aloe glauca but Aloe lineata var. lineata. Like this one from a nursery in Holland.

Hi Arinda,

Lineata and glauca are closely related and indeed I had mine as lineata for some years although it is a cutting from the original Kew plant. Your nursery plant is similar but way bigger than mine.

I wrote an article a little while back on this but afterwards received the attached and I have reverted to the Kew name of Aloe Glauca -


Steven Thompson emailed me to
say that Mike’s plant is actually
Aloe glauca. He continued, “It is a
proliferous selection of that
species which retains juvenile
fan-like shoots for much longer
than the type.
“It was found by Peter Brandham
of Kew in a South African garden
centre in the early 1980s...
unfortunately he did not record
the name of the garden centre.
“He called it Aloe glauca forma
distincta but I have not found
evidence that he formally
described it as such. He passed
offsets of it to Abbey Brook
Cactus Nursery from which it was
made available under this name.”
Peter Brandham had been
working on research at Kew, but
they disposed of his plants after
he retired. The only survivors
were those plants which he had
sent previously to Abbey Brook
and a few other people.
See SANBI (the South African
National Biodiversity Institute) for
some more information on Aloe
lineata subsp. muirii.

Yes. It's Aloe glauca. Noticed no one ever responded to you.
