The Aucuba japonica, commonly known as the Japanese laurel, spotted laurel, or even the gold dust plant (in the US), is a popular ornamental shrub prized for its attractive foliage. Here's a closer look at its leaves:

General characteristics:

  • Size and Shape: Aucuba japonica leaves are typically broad and lanceolate, meaning they're wider in the middle and taper towards both ends. They can range from 8 to 25 cm in length and 2 to 12 cm in width.
  • Texture and Shine: One of the most striking features of these leaves is their leathery texture and glossy sheen. This makes them appear almost polished and adds to their elegant look.
  • Arrangement: The leaves grow opposite each other on the branches, creating a tidy and uniform appearance.

Color Variations:

  • Solid Green: The classic Aucuba japonica has vibrant, deep green leaves. This solid color makes them a perfect backdrop for other plants with more vibrant flowers.
  • Variegated Varieties: What truly sets this shrub apart are the numerous variegated cultivars. These varieties boast beautiful patterns and splashes of color on the green background. Some popular examples include:
    • ' سلطان القهوة (Sultan of Coffee)' (Sultana): This cultivar features bright yellow spots scattered across the green leaves.
    • 'Gold Dust': As the name suggests, this variety has a dusting of golden speckles on the green foliage.
    • 'Griffo': This cultivar stands out with broad, yellow margins framing the green center of the leaf.

Additional details:

  • Leaf Edges: While the base of the leaf is typically broad and wedge-shaped, the margins can vary. Some varieties have smooth edges, while others boast a coarsely toothed margin, particularly near the tip.
  • Leaf Sheath: The base of the leaf stalk (petiole) is often enclosed by a sheath that wraps around the stem.

With their diverse color options, glossy texture, and evergreen nature, Aucuba japonica leaves add a touch of year-round elegance to gardens and landscapes. They're also tolerant of shade, making them a great choice for areas with less direct sunlight.
