One of the distinguishing features of Agave desmettiana is its compact size compared to some of its larger relatives. It typically grows to a height of about 1 to 2 feet (30 to 60 centimeters), with a similar spread, making it suitable for smaller gardens, containers, or as a focal point in rock gardens. Despite its diminutive stature, this agave still commands attention with its rosette of broad, smooth, blue-green leaves that taper to a sharp point at the tip. The leaves lack the serrations or teeth found on many other agave species, giving Agave desmettiana a sleek, streamlined appearance.
