Whats Happening in the Garden

The garden is beginning to hibernate for fall and winter. Leaves are falling but there is ALWAYS something blooming in this garden. In the last two weeks the poinsettas have gone from green bushes to red tipped which are now poinsetta blooms. These are so prolific in Mexico and women will be selling them by the armloads at Christmas time. The butterflies love the blooms and literally swarm the tree all day long. Now the picture below is of a HUGE plant with spiky orange blooms. The orange stalks are actually tiny, tiny individual orange blossoms

and the hummingbirds swarm this poking their nose into each and every flower. The "leaves" look like aloe verde but I'm not sure. Anyone have any idea what this plant is called?

I can see both the poinsetta and the orange spiked plant from the living room windows as I sit on the chaise to read in the afternoon. With all the movement from the hummingbirds and butterflies, it is a sight to behold!
