This grower is fairly sure of this plant identification.
This plant is about 9 years old, 45cm tall and spreading 40cm. It's tough and indestructable but grows very slowly indeed! It's also thorny and not a good plant to have around a toddler! That's why I am looking for a new, loving home for it.
The plant requires full sun but cannot go outside! I made that mistake about four years ago - the crown got wet and the tips of the new leaves are still affected! Got the memory of an elephant...
It would love a sunny spot in a conservatory, though!

Aloe dichotoma (Quiver tree ). This slow-growing species of aloe is evergreen with an open branched habit. The foliage is produced in terminal rosettes of strap-shaped medium-green leaves. The flowers are bright yellow, with red stamens and borne in terminal clusters.
The stems repeatedly branch which is where the specific epithet 'dichotoma' comes from.
When grown under glass, grow in a loam-based compost in full light. When grown outdoors, grow in a fertile well-drained soil with full sun.
