Acer palmatum 'Emerald Lace' (Artar Japonez)

Acer palmatum 'Emerald Lace' , also known as the 'Emerald Lace Japanese Maple', is a cultivar of the species Acer palmatum in the Sapindaceae family. This deciduous shrub is notable for its fine, deeply lobed, vibrant emerald green foliage and its spectacular fall colors. Native to Japan, 'Emerald Lace' is an excellent choice for ornamental gardens, Japanese landscapes and bonsai due to its delicate texture, compact stature and graceful appearance.

Appearance of leaves, flowers and fruits

• Leaves : The leaves are deeply lobed, with 5-7 extremely thin and finely dissected, lace-like lobes, of a brilliant emerald green in spring and summer. Their airy texture and serrated edges create a delicate visual effect. In autumn, the leaves turn to intense shades of bright red, purple and orange , providing a dramatic color show. The leaves are small, 4-6 cm, emphasizing the delicate appearance of the plant.
• Flowers : The flowers are small, purple, grouped in discrete clusters, appearing in April-May . They are ornamentally insignificant, 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 contribute significantly to the aesthetics of the plant.

Growth characteristics

• Height and width : It grows as a compact shrub, reaching 2-3 meters tall and 2-3 meters wide , with a rounded, slightly arched crown and a weeping habit. Its slow growth makes it ideal for small gardens.
• Vigor : It has slow growth, with fine and flexible branches, which enhance its delicate appearance.
• Type : It is a deciduous shrub, with fine branching that highlights the textured foliage.

Growing conditions

• Exposure : Prefers partial shade or filtered sun , ideally under sparsely-crowning trees or near an east-facing wall. Full sun can burn the delicate leaves, especially in warm climates, and dense shade reduces the intensity of the fall colors.
• Soil : Requires fertile, well-drained soil with a slightly acidic to neutral pH (5.5-7). A mixture of garden soil, compost and peat is ideal. Does not tolerate waterlogged or chalky 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 : Flowers attract pollinators, but fruits are not relevant for ornamental value.

Care and resistance

• Hardiness : It is hardy to -20°C (zones 5-8), making it suitable for temperate climates, including Romania. Young leaves can be affected by late frosts, and the delicate branches require protection in harsh winters.
• Fertilization : 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. Severe pruning can disrupt the delicate natural appearance.
• Pests and diseases : May be affected by mites, aphids or verticillium wilt. The fine leaves are sensitive to sunburn or strong winds. Good ventilation and drainage prevent problems.
• Fauna : The flowers attract bees, and the berries can be eaten by small birds.

Use
