The Shasta Daisy, or Leucanthemum x superbum, is a perennial flowering plant best known for its classic white blooms and yellow center. Here are some key points about the Shasta Daisy:

Appearance: Shasta Daisies are known for their white, saucer-like blooms and bright yellow center. These flowers rest on thin stems that are lined with glossy green leaves. The Shasta Daisy is a semi-evergreen and forms dense, bushy clumps. 

Size: Overall, the Shasta Daisy grows 1-4 feet high and 1-2 feet wide. Its blooms typically span 2-5 inches wide. Its compact size and dense habit make it a great choice for smaller landscapes. 

Flowering: Shasta Daisies bloom in the spring and summer seasons. In some climates their blooms can last until the early fall, giving them the potential for a long bloom season. 

Sun and Soil Requirements: Shasta Daisies will grow best and have more prolific blooms when planted in full sun. However, they can take some 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.

Watering: Shasta 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.

Maintenance: Shasta 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.

Landscape Use: Shasta Daisies are commonly used in container gardens, mixed landscape beds, and naturalized areas. They also work well as cut flowers for floral arrangements.

Overall, Shasta 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 and are an excellent choice for any garden space.
