Description
Acer 'Atropurpureum' brings a quiet sort of drama to the garden—the kind that never needs to raise its voice. This slow-growing purple Japanese maple forms a graceful, bushy small tree that matures into a beautifully shaped multi-stem specimen, perfect for lending structure and colour without overwhelming its surroundings. In spring, Acer palmatum 'Atropurpureum' unfurls deeply cut leaves in rich bronze-crimson to dark purple-red tones, each one finely divided into elegant lobes that seem almost hand-drawn. Tucked among the foliage, small red-purple flowers appear with admirable modesty, sometimes followed by decorative purple winged fruits.
As the season moves on, Acer 'Atropurpureum' earns its keep many times over. Its finely dissected foliage holds that sumptuous dusky colouring through summer before turning a brilliant, luminous red in autumn—a finale well worth waiting for. Use Acer 'Atropurpureum' as a focal point in a courtyard, among shade-loving perennials, or in a large container where its refined silhouette can be admired up close. Even in a smaller garden, Acer palmatum 'Atropurpureum' feels entirely at home, adding an artistic, almost serene quality that few shrubs or trees can rival. It is, quite simply, one of those plants that makes everything around it look better behaved.
Acer is the Latin name for maple, meaning sharp—a nod to the pointed shape of the leaves.

Useful information
-
Soak the Acer 'Atropurpureum' roots in water for 3-6 hours prior to planting
Plant your "Purple Japanese maple" bare roots into temporary pots with a multipurpose compost within a week of delivery and grow-on in a sheltered spot outdoors
Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).
Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
