That first pic is a perfect "Maraih", well, almost perfect. Mine is in a pot. yours in the ground are much like those of mine in ground, They are beginning to be a problem getting into and out of the car; I suppose I'll have to whack a few limbs off. also, your caudex on the ones your showing look good. Do you plan on raising it up a bit? I wonder how long it will be before some one says you should put down mulch
. I've done the mulch thing with and without plastic, and just prefer it natural like you have yours. I've lost all my pictures when I had to take my computer in to clean the "F.B.I." virus. Maybe I'll get a chance to get out and take more pics.
