Acer palmatum 'Butterfly' (Japanese Maple)

Acer palmatum 'Butterfly' , also known as the Japanese Butterfly Maple, is a cultivar of the species Acer palmatum in the Sapindaceae family. This deciduous shrub or small tree is renowned for its variegated foliage, with delicate leaves in shades of green and cream, and for its graceful appearance, making it a popular choice for ornamental gardens, Japanese landscapes and bonsai. Originally from Japan, 'Butterfly' adds subtle charm with its variegation and seasonal colors.

Appearance of leaves, flowers and fruits

• Leaves : The leaves are palmate, with 5-7 thin lobes, medium green with cream or pinkish-white edges and spots, creating a distinctive variegated effect. In spring, new leaves may have pale pink edges, fading to cream in summer. In autumn, the leaves turn shades of pink, red and purple , providing a colorful spectacle. The leaves are small, 4-6 cm, and delicate, giving an airy appearance.
• 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 or small tree, reaching 2-3 meters tall and 1.5-2.5 meters wide , with a rounded, slightly arched crown. Its slow growth makes it ideal for small spaces.
• Vigor : It has slow growth, with fine branches and a delicate structure, suitable for ornamental landscapes.
• Type : It is a deciduous shrub/tree, with fine branching that accentuates its graceful appearance.

Growing conditions

• Exposure : Prefers partial shade or filtered sun , ideally under sparsely canopyed trees or near an east-facing wall. Full sun can burn the variegated leaves, especially the cream areas, and dense shade reduces the intensity of the variegation.
• 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 variegated areas are more sensitive to stress.
• Fertilization : Apply a balanced fertilizer (e.g. 10-10-10) in early spring to stimulate growth. Avoid excess nitrogen, which can reduce variegation.
• Pruning : Prune minimally in January-February to remove dead or crossing branches and maintain shape. Severe pruning can affect the natural appearance.
• Pests and diseases : May be affected by mites, aphids or verticillium wilt. Variegated areas are more susceptible to sunburn or fungal diseases. Good ventilation and drainage prevent problems.
• Fauna : The flowers attract bees, and the berries can be eaten by small birds.

Use

Acer palmatum 'Butterfly' is ideal for Japanese gardens , cottage gardens or as a solitary plant in small spaces. The variegated foliage adds contrast when combined with plants such as hostas, ferns or azaleas. It can be grown in containers on patios, but requires protection from wind and cold. It is perfect for creating delicate focal points in ornamental landscapes.
