It's not only in the greenhouse that the aloes have been busy, the two flowering garden aloes also have seed pods ripening.
Strangely both the aloe aristratas have one seed pod each, from the last flower on the stem. More exciting is the aloe striatula which has a good collection of seed pods.
I am not sure if these are self fertile, if not they must be hybrids with the a. aristrata. Sadly this doesn't seem to produce the interesting plants you would hope for, taking the less interesting parts of both parents.
I will just have to try germinating them and see what they turn into.
