Red Japanese Maple Seeds (Acer palmatum ‘Atropurpureum’) – Dormant Bonsai Seed

Johnny Mapleseed

Grow one of the most iconic and elegant Japanese maples from seed. Red Japanese Maple (Acer palmatum ‘Atropurpureum’) is prized for its graceful form, fine-textured foliage, and dramatic seasonal color changes. From spring through winter, this maple delivers year-round visual interest, making it a standout choice for bonsai artists and landscape growers alike.

In spring, deeply cut leaves emerge in rich red tones, gradually softening to green in summer before igniting into brilliant shades of gold, orange, and red in fall. Winter reveals the tree’s refined branch structure and smooth gray bark, creating a striking silhouette—especially admired in bonsai displays.

Reaching approximately 20 feet tall and wide in the landscape, this compact maple forms a graceful, vase-shaped canopy with upright branching. It is slightly hardier than many green-leaved Japanese maples and performs well in USDA zones 5B–8. Flexible branches, refined internodes, and excellent response to pruning make it a favorite for bonsai cultivation.
