Kate,
These guys love more water than other Aloes. The soil must be free draining so no water can collect. During summer they may need water every day. I just got another batch of seeds which I have more than 40 plants. Takes 4 years to see spiraling. Don't let the temp go below 30 and if so, never water at that low temp. I don't know what the lowest they could go. Maybe to 25 but I would get it covered up. Your area heat may be a bigger problem. No direct sun only partial. Planted on a side of a hill for good drainage. Got to show us a picture of it. Also good for your record to check back on.
