Acer palmatum dissectum 'Lionheart'

Lionheart Japanese Maple

Acer palmatum dissectum ‘Lionheart’ is a refined weeping laceleaf Japanese maple valued for its rich red foliage, graceful cascading habit, and excellent color stability. Spring foliage emerges deep crimson-red, maturing to a dark burgundy-red that holds well through summer, especially in partial shade.

The finely dissected leaves create a soft, flowing texture as branches arch outward and downward, forming an elegant, mound-shaped silhouette. In fall, ‘Lionheart’ intensifies to brilliant scarlet and fiery red, delivering a strong and dependable autumn display.

The habit is low, spreading, and gracefully weeping, making it an ideal focal point in the landscape. It performs best in partial shade, with protection from harsh afternoon sun and wind, and prefers well-drained, evenly moist soil.
