Acer palmatum 'Phoenix' (Japansk lönn)

Acer palmatum 'Phoenix' is a cultivar of Japanese maple from the Sapindaceae family, renowned for its vibrant foliage and compact form. This deciduous shrub or small tree is valued for its spectacular seasonal colors, ranging from bright red in spring to yellow-orange in autumn, and for its reddish bark, which adds interest in winter. It is ideal for ornamental gardens, Japanese-style landscapes, containers, or bonsai, thanks to its elegant appearance and small size.

Appearance of leaves and flowers

• Leaves: The leaves are hand-shaped, with 5-7 slender lobes, 4-7 cm long, with finely serrated edges. In spring, they are a bright pinkish red, turning reddish-green in summer and changing to intense yellow with orange or red highlights in autumn. The foliage is delicate, giving an airy look.
• Flowers: The flowers are small, purple, grouped in clusters, appearing in April-May. They are not ornamental but attract pollinators such as bees.

Growth characteristics

• Height and width: Reaches 2-3 m in height and 1.5-2 m in width, forming a compact shrub or small tree with a rounded, slightly arching crown.
• Vigor: Slow to moderate growth, with fine branches and a graceful structure, suitable for small spaces.
• Type: Deciduous shrub or tree, with reddish bark that becomes more vibrant in winter.

Growing conditions

• Exposure: Prefers partial shade or filtered sun, ideally under trees with sparse crowns or near an east-facing wall. Full sun can scorch the leaves, and dense shade reduces color intensity.
• Soil: Grows in fertile, well-drained soils with slightly acidic to neutral pH (5.5-7.0). Add compost or peat at planting. Does not tolerate waterlogged soils.
• Watering: Water regularly, keeping the soil consistently moist but not wet. Mulch with bark to retain moisture.
• Temperature: Hardy in zones 5-8 (down to -20°C), suitable for temperate climates, including Romania. Protect roots with mulch during harsh winters.

Care and resistance

• Hardiness: Cold-hardy, but young leaves may be affected by late frosts. May attract aphids or mites; treat with insecticidal soap. Tolerates moderate urban pollution.
• Fertilizing: Apply a balanced fertilizer (e.g., 10-10-10) in early spring. Avoid excess nitrogen, which affects seasonal colors.
• Pruning: Prune minimally in January-February, removing dead or crossing branches. Avoid heavy pruning to maintain natural shape.
• Propagation: Propagated by semi-woody cuttings in summer or grafting. Seeds are less effective due to hybrid nature.

Uses
