Broad heart-shaped leaves, pale veins and a velvety surface reflect the Philodendron gloriosum × Philodendron pastazanum parentage of Philodendron 'Dean McDowell'. The plant grows from a creeping rhizome that moves horizontally across the pot, so wider containers suit its natural direction of growth. Philodendron tissue contains calcium oxalate crystals, so placement should account for pets and small children. As leaves mature, the vein network becomes more pronounced and the plant builds a broad, rounded leaf mass. An airy aroid mix with even moisture supports the rhizome and roots.
