Ruby Heart Coleus, Premium Sun

Premium Sun Ruby Heart is an upright coleus with heart-shaped ruby-red leaf tops, yellow-green undersides, and a thin chartreuse border. PanAmerican lists mature height at 18–26 inches and width at 18–22 inches, with exposure to shade and sun. ## Foliage and placement The contrasting leaf colors provide a bright accent in landscapes, garden beds, or patio containers. Ball describes the colors as long-lasting and identifies Ruby Heart as a shade-tolerant, low-maintenance selection. The general Premium Sun guidance allows full sun where humidity is high and cautions that low-humidity full sun can scorch foliage. ## Light and water The exact product page lists 12–18-inch spacing. Ball rates water needs as medium and recommends fertilizer every two weeks. In dry air, choose shade or filtered light to protect the leaves. ## Maintenance Ruby Heart is grown for its foliage; its bright margins and red surfaces are the main display.
