Acer palmatum Atropurpureum Purple Maple

Description:
Purple Japanese Maple (Acer palmatum 'Atropurpureum') is a stunning deciduous tree known for its deep purple foliage and elegant, multi-branched form. This classic Japanese maple cultivar is prized for its vibrant leaf color, which provides a striking contrast in gardens and landscapes. Its compact size and rich color make it ideal for small gardens, borders, and as a feature tree in mixed plantings.

Flowers:
In spring, 'Atropurpureum' produces small, purple-red flowers that are subtle but add an additional ornamental touch to the tree before the leaves emerge fully.

Foliage:
The tree features finely divided, palmate leaves that emerge a rich purple-red in spring and retain their color through summer. In autumn, the foliage transitions to vibrant shades of crimson and orange, adding stunning seasonal interest. The deeply lobed leaves create a delicate, lacy appearance that enhances the tree's graceful shape.

Fruit:
After flowering, small, winged samaras (helicopter seeds) develop in late summer to early autumn. These seeds add subtle interest and often take on a reddish hue, complementing the foliage.

Form and Size:
Purple Japanese Maple has a compact, rounded growth habit, typically reaching a height of 4 to 5 meters with a spread of 3 to 4 meters. Its moderate size and rounded form make it well-suited for smaller landscapes, patios, or as a focal point in garden beds.

Growing Conditions:
This tree thrives in partial shade to full sun, though it prefers some protection from harsh afternoon sun in warmer climates to prevent leaf scorch. It grows best in moist, well-draining, slightly acidic soil enriched with organic matter. Regular watering during dry periods is essential, especially for young trees.

Uses:
Atropurpureum is ideal as a feature tree in gardens, borders, and as a standout specimen in mixed plantings. Its bold color and graceful form make it perfect for Japanese-style gardens, woodland landscapes, and as an understory tree.

Maintenance:
This variety is relatively low-maintenance, requiring minimal pruning. Light pruning in late winter helps maintain shape and remove any dead or crossing branches. Mulching around the base helps retain soil moisture and protect roots, and fertilizing in spring with an acid-loving plant fertilizer supports healthy growth.

Notes:
Purple Japanese Maple is highly regarded for its dramatic foliage and adaptability to a range of climates. Its bold, seasonal color changes make it a popular choice for gardeners looking to add texture and color to shaded and partial-sun areas of the landscape.

Companion Plants:
Pairs well with other shade-loving plants like Hostas, Ferns, and Azaleas. It also complements other Japanese maples and woodland perennials, creating a serene, layered aesthetic in the garden.
