AG, when it comes to A. sisalana this is what you have to look forward to:
The wall is about 7 ft tall...
It will probably not grow as fast in the raised bed, but it will likely root down into the regular yard surface so will not be slowed down forever. When I planted mine, it had three pups. I potted those up and they got frost damage from the one really cold night we had last winder, the plant in the ground did just fine. One thing I have learned from all the A. weberi's I have grown is to try and harvest the pups as well as I can, otherwise these monsters will already have monster juniors growing right next to them when they flower and then digging stuff up is even harder... So from now on I am going to be pro-active in cutting away older/dead leaves which will make harvesting the pups easier as well.
If you were going to move it, move it sooner rather than later - A. sisalana is a little frost sensitive but if it is happily in the ground it should be fine unless it gets really down into the 20s...
With regards to putting things in the ground I really only stop when it is forecast to get cold and/or wet on the days that I might have planned to plant the plant or shortly after, and I might not plant plants that I know are especially cold or wet sensitive during December-January. I am generally so pressed for time in keeping up with all the planting and repotting that I have to do, given that the planting season does not really start until sometime in October and I feel that it does not last much beyond March (if that), that I cannot afford to take a big break that is not 108F + related... Also I feel that if I plan to plant things the longer they have before the summer hits the better even if that means that the plants have to suffer through some cold/wet spells - they would be doing it in their pots anyway, sun adjustment is way harder for a plant you cannot easily move into the shade if it starts showing sun stress. Ideally I get it all done in October-November, but given the full time job and other chores around the house (and the dog) that is simply not a realistic expectation to have. I really see a clear difference in how plants fare through their first summer based on when I put them in the ground, plants that I got into the ground in the Fall generally do much better than those I planted in the Spring - most of my fatalities from this Summer were from the batch of plants I planted in the Spring...
