Acer palmatum 'Orange Dream'

Acer palmatum 'Orange Dream', also known as the "Japanese maple Orange Dream," is a cultivar of the species Acer palmatum from the Sapindaceae family. This deciduous shrub or small tree is renowned for its vibrant foliage, which undergoes spectacular color changes throughout the seasons, and for its compact, graceful shape. Native to Japan, 'Orange Dream' is a popular choice for ornamental gardens, Japanese-style landscapes, and bonsai, due to its warm colors and delicate appearance.

Appearance of leaves, flowers, and fruits

• Leaves: The leaves are palmate, with 5-7 slender lobes, a in spring, sometimes with pinkish-red edges. In summer, the leaves turn a yellowish-green, maintaining a warm shade, and in autumn they change to deep orange and golden red, offering a vibrant visual display. The leaves are medium-sized, 4-7 cm, with finely serrated edges, giving an airy look.
• Flowers: The flowers are small, purple, grouped in discreet clusters, appearing in April-May. They are not significant ornamentally but attract pollinators such as bees.
• Fruits: The fruits are double samaras, initially reddish, turning brown at maturity, 1-2 cm long. They appear in summer but do not significantly contribute to the plant’s aesthetic.

Growth characteristics

• Height and width: It grows as a compact shrub, reaching 2-3 meters in height and 2-3 meters in width, with a rounded, slightly arching crown. Its slow growth makes it ideal for small or medium gardens.
• Vigor: It has slow to moderate growth, with fine branches and a delicate structure, suitable for ornamental landscapes.
• Type: It is a deciduous shrub/tree, with fine branching that highlights the colorful foliage.

Growing conditions

• Exposure: Prefers partial shade or filtered sunlight, ideally under trees with sparse crowns or near an east-facing wall. Full sun can burn the delicate leaves, especially in spring, while dense shade reduces color intensity.
• Soil: Requires fertile, well-drained soil, with a slightly acidic to neutral pH (5.5-7). A mix of garden soil, compost, and peat is ideal. It does not tolerate waterlogged or calcareous soils.
• Watering: Needs regular watering, keeping the soil consistently moist but not flooded. A layer of organic mulch (e.g., bark) helps retain moisture.
• Pollination: The flowers attract pollinators, but the fruits are not relevant for ornamental value.

Care and resistance

• Hardiness: It is hardy to temperatures down to -20°C (zones 5-8), suitable for temperate climates, including Romania. Young leaves can be affected by late frosts, and the plant requires protection in harsh winters.
• Fertilizing: Apply a balanced fertilizer (e.g., 10-10-10) in early spring to stimulate growth. Avoid excess nitrogen, which can affect seasonal colors.
• Pruning: Prune minimally, in January-February, to remove dead or crossing branches and maintain shape. Heavy pruning can affect the natural appearance.
• Pests and diseases: May be affected by mites, aphids, or verticillium wilt. Delicate leaves are sensitive to sunburn under extreme conditions. Good ventilation and drainage prevent problems.
• Wildlife: Flowers attract bees, and the samaras may be eaten by small birds.

Usage
