This gem had been floating around California as an Agave americana without a valid cultivar name when it was christened Agave 'Lemon Lime' by agave expert Brian Kemble. In fact, it seems to be a form of Agave x protamericana from the Mexican population where Agave americana intergrades with Agave asperrima (scabra)...hence, the rough leaf back. Agave 'Lemon Lime' makes a stunning 4' tall x 4' wide clump of very wide blue leaves, each highlighted with a 6" wide chartreuse stripe down the center. Agave 'Lemon Lime' does produce offsets, but never enough to have lots of this gem. When it finally flowers, the 20'+ flower spike will be topped with fragrant, yellow, hummingbird-attracting flowers.
