What to plant around an Agave americana medio-picta alba?
I am about to plant an Agave americana medio-picta alba in the midst of a tropical bed. In order to avoid overwatering the plant, I am going to mound up some sandy soil on top of a layer of gravel. The plant is small, but the mound will be large to leave space for growth. What small plants/succulents could I place around it in order to fill in the mound?
