When I brought home the pots of agave utahensis at the weekend my OH commented on one of the pots crammed full of plants and how good they looked as mass of leaf and spine. What struck me most was that when I look at the same pot I see a mess and that you can not see the true shape and structure of the indivual plants. This got me thinking about why most people seem to keep agaves as individual plants instead of clumps.
For me I suspect it could be something to do with the strong structural form of agaves. Looking at the plants I like, they tend to be the more defined structured plants. No doubt I have mentioned several times that I like the order and neatness they bring (no doubt followed by laughs from my OH as she looks around the mess inside the house). I think you would loose this order in a clump and maybe that's what stops me.
Strangely in the ground I am more relaxed and the agave parryis in the front have several pups which while I have considered removing them, I have never bothered. Dry beds, no matter how hard you try never seem to reach the level of neatness you get in pots and so I try not to replicate them, letting the plants grow a bit more naturally.
