The "Butterfly" Japanese maple, also known as Acer palmatum 'Butterfly', is a cultivar of Japanese maple tree renowned for its stunning variegated foliage. Here's some information about it:

1. Appearance: Butterfly Japanese maple is prized for its unique foliage, which features creamy white margins that contrast beautifully with the green center of the leaves. The leaves have a delicate, lace-like appearance and typically emerge with pink tones in spring. In fall, the foliage may turn shades of yellow, orange, or red, adding to its ornamental value.

2. Size: This cultivar typically grows as a small to medium-sized tree, reaching heights of about 7 to 12 feet with a similar spread. However, the ultimate size can vary depending on growing conditions and pruning practices.

3. Sunlight: Butterfly Japanese maple prefers partial shade to full sun. It tends to perform best when protected from the harsh afternoon sun, especially in hotter climates, to prevent leaf scorch.

4. Soil: It grows best in well-draining, acidic soil with good organic content. Ensure the soil is moist but not waterlogged, as Japanese maples are sensitive to waterlogged conditions.

5. Watering: Keep the soil consistently moist, especially during the tree's establishment period. Once established, provide regular watering, particularly during dry spells or hot weather.

6. Pruning: Pruning is generally minimal and should be done with care to maintain the tree's natural form and showcase its attractive foliage. Remove any dead, damaged, or crossing branches and prune lightly to maintain the desired shape.

7. Fertilizing: Apply a balanced fertilizer in spring to provide essential nutrients for healthy growth. Follow the manufacturer's recommendations for application rates and timing.

8. Landscape Uses: Butterfly Japanese maple is an excellent choice for adding color and interest to garden beds, borders, and landscapes. It can also be grown in containers or used as a focal point in smaller gardens. Its striking variegated foliage makes it particularly eye-catching when planted against a backdrop of evergreen shrubs or darker foliage plants.

Overall, the Butterfly Japanese maple is prized for its stunning foliage and adds a touch of elegance and beauty to any garden or landscape setting. With proper care and maintenance, it can be enjoyed for years to come.
