This is a Kelly Griffin cultivar. This plant is a mutated monstrose form of Agave potatorum. Marginal spines can grow on up to all four of the leaf sides. The leaves grow as if 2 leaves are fused together forming a square shape. Grow this plant in full sun to partial shade.
Googled it. Should have done this before purchase. You know you always find them cheaper after you purchase one. But the ones I see for sale doesn't seem as large or so that's what I tell myself.
