I settled on an Agave lophantha 'Quadricolor'. I may eventually need to add some type of border or cascading plants, though this species is known to pup quite a bit. For now, I'll just wait and see how it settles in.
As I finished emptying out my pop-up greenhouse, I used the opportunity to finally get some specimens into pots.
Spekboom (Portulacaria afra)
Variegated Soap Aloe (Aloe maculata 'Variegata')
(replacing Senecio scaposus which struggled)
I also got my last Turk's Cap 'Big Momma' (Malvaviscus drummondii x arboreus 'Big Momma') into one of the garden beds. The rest of the time was spent watering recent plantings and continuing the excavations.
