Returns Simplified.Acer palmatum Atropurpureum is one of the most widely grown and recognised Japanese maples, admired for its striking purple-red foliage and graceful form. It is actually a group name covering many seed-grown red Japanese maples (rather than a single clone), so individual plants can vary slightly but all share that characteristic rich colour and elegant silhouette.
Foliage: Classic palmate leaves with 57 finely pointed lobes emerge a deep crimson-red in spring, mature to a rich purple-red through summer, then turn brilliant shades of scarlet and crimson in autumn, giving an extended season of vibrant colour.
Habit: Develops into a small, upright tree or large shrub, usually growing 35 metres high, with a similar spread over time. It forms a rounded, often slightly layered canopy.
Bark: Smooth grey-brown branches add subtle structure in winter.
Because of its reliability, easy growth and vivid foliage, Atropurpureum is widely used as a feature tree in lawns, mixed borders, Japanese-style gardens and even large pots.
Prefers partial shade or dappled sunlight.
Will tolerate more sun than many other red-leaved acers, but still best sheltered from hot afternoon sun to reduce risk of leaf scorch.
Always plant in a protected position, out of strong or drying winds.
Important to avoid exposed sites where wind can tear or dry delicate leaf margins, leading to browning.
Likes soil to be consistently moist but well-drained.
Water thoroughly during dry periods, particularly when newly planted or if grown in containers.
Apply a mulch of compost or bark in spring to help conserve moisture and keep roots cool.
Prefers slightly acidic to neutral, fertile, humus-rich soil.
Avoid very alkaline or heavy clay soils. If needed, plant in raised beds or large containers using ericaceous compost mixed with grit for drainage.
Feed lightly in spring with a balanced slow-release fertiliser or a specialist acer feed.
Avoid high-nitrogen fertilisers which encourage soft growth more prone to wind or frost.
Requires minimal pruning.
Remove any dead, damaged or crossing branches in late autumn or winter while dormant.
Avoid hard pruning which disrupts its graceful natural form.
Generally very healthy and trouble-free.
May occasionally see aphids on new growth.
Leaf scorch (browned edges or tips) is typically caused by drought, strong wind or excessive sun, not disease.
Well-suited to large pots, making it ideal for patios or small gardens.
Use ericaceous compost with added grit, ensure the container has good drainage and is raised on pot feet.
Water consistently, and protect pots in harsh winters by wrapping or moving to a sheltered location.
