This is about the greenest I've ever seen this plant. Here for comparison are some other pictures.

This is the same plant back in May, while it was still a rootless cutting. The color is due to the rootlessness, not the exposure. One handy feature about these plants is you know when cuttings are rooted based on the color change, just like a stoplight.



Here is the parent of that offset a year ago growing in a very sunny location. The color here is due to the sun and only the newest growth is green.



But the mother plant has gone through other shades of yellow and orange, depending on the season and the cloud cover.



As landscape plants here they turn red for our annual summer drought, along with some shriveling and changes in leaf shape (they become channeled and recurved).



All those plants are the same genetically identical clone of Aloe dorotheae, just experiencing life differently, sometimes in dramatic ways.
