Abstract

A new and distinct cultivar of Aechmea plant named ‘Don Juan’, characterized by its relatively large plant habit with upright growth habit; long and broad green-colored leaves that are variably and heavily tinged with burgundy; freely-flowering habit with large inflorescences held upright and above the foliar plane on straight strong dark red-colored scapes; large upwardly-branched inflorescences with flower bracts that are initially yellow and becoming yellow and dark red with subsequent development; long-lasting inflorescences and good container and interiorscape performance; and relative resistance to Helminthosporium Leaf Spot (Exserohelium sp.).

Claims
