We first got this stunning selection of Agave salmiana from Marsha McPhetters's California garden, where it made a 3' tall x 4' wide clump. The upright growing rosette of concave, glossy, dark green leaves is dramatically highlighted by a creamy yellow margin. We have grown at least two other margined forms of Agave salmiana. While some Agave salmiana cultivars are winter-hardy to 5 degrees F, we are just now trialing this selection outdoors. Thanks to Brian Kemble of the Ruth Bancroft Garden for assisting with naming this agave. Agave flowers attract hummingbirds.
