The Montauk daisy, scientifically known as Nipponanthemum nipponicum or Chrysanthemum nipponicum, is a perennial flowering plant native to Japan. Here are some key points about the Montauk daisy:

1. Appearance: Montauk daisies are known for their large, daisy-like flowers with white petals and yellow centers. Each flower typically measures 2 to 3 inches (5 to 7.5 cm) in diameter. The plant forms dense, bushy clumps with dark green, leathery leaves that are lance-shaped and serrated along the edges. The foliage remains evergreen in mild climates.

2. Size: Montauk daisies can grow to a height of 2 to 3 feet (60 to 90 cm) and spread to a width of 2 to 3 feet (60 to 90 cm). They have a mounding growth habit and tend to form large, rounded clumps over time.

3. Flowering: Montauk daisies bloom in late summer to early fall, typically from August to October, depending on the climate. The flowers are long-lasting and provide a cheerful display of white blooms well into the fall season.

4. Sun and Soil Requirements: Montauk daisies prefer full sun to partial shade. They thrive in well-drained soil with average fertility. While they can tolerate a range of soil types, they perform best in soil that is moist but well-draining.

5. Watering: Montauk daisies have moderate water needs and benefit from regular watering, especially during hot, dry periods. However, they are somewhat drought-tolerant once established and can withstand short periods of dryness.

6. Maintenance: Montauk daisies are relatively low-maintenance plants. Deadheading spent flowers can help promote continued blooming and prevent self-seeding. Pruning may be necessary in early spring to remove dead or damaged growth and shape the plant.

7. Landscape Use: Montauk daisies are commonly used in perennial borders, cottage gardens, and mixed flower beds, where their late-season blooms add color and interest. They also work well as cut flowers for floral arrangements.

Overall, Montauk daisies are valued for their showy flowers, long blooming period, and ease of care. With their bushy growth habit and evergreen foliage, they provide year-round interest in the garden and are popular choices for adding late-season color to garden landscapes.
