Growth Stages

1

Establishment

4-6 weeks

Transplants develop roots and new foliage growth begins; plants gradually increase in size

Keep soil moist, avoid waterlogging; stake if needed for support; deadhead any early flowers to encourage root development

2

Vegetative Growth

6-8 weeks

Plant develops sturdy stems and dense foliage, reaching full height before flowering begins

Continue regular watering; apply balanced fertilizer monthly; pinch back growing tips in late spring to encourage bushier growth and more blooms

3

Bud Formation

2-3 weeks

Flower buds appear at stem tips as days lengthen in early summer; buds gradually swell and develop color

Maintain consistent moisture; reduce nitrogen fertilizer to avoid excessive foliage; provide stakes or supports if stems appear weak

4

Flowering

6-8 weeks

Semi-double white flowers with yellow centers open fully, displaying attractive pompom-like form; blooms persist for several weeks

Deadhead spent flowers regularly to extend bloom time; water at soil level to keep petals dry; apply dilute fertilizer every 2-3 weeks

5

Senescence & Dormancy

Ongoing through fall and winter

Flowers fade, stems begin to brown; plant prepares for winter dormancy

Stop fertilizing; reduce watering; cut back stems to 3-4 inches after first frost; apply 2-3 inches of mulch for winter protection in colder zones

Harvest Tips

Cut flowers in early morning when dew has dried but before heat of day; cut stems at an angle just above a leaf node; place immediately in cool water with floral preservative. Flowers last 7-10 days in a vase. Deadhead faded blooms throughout the season to encourage continuous flowering. For dried arrangements, cut fully open flowers and hang upside down in a cool, dry location for 2-3 weeks.

Fun Facts

  • 🌱 Shasta daisies were created by horticulturist Luther Burbank in 1901 through selective breeding of Chrysanthemum maximum (ox-eye daisy), Chrysanthemum lacustre, and Chrysanthemum nipponicum. He named them after Mount Shasta in California.
  • 🌱 The 'Phyllis Smith' cultivar is known for its distinctive semi-double to double form with multiple rows of petals, distinguishing it from single-petaled Shasta varieties and creating a more ornamental, pompom-like appearance.
  • 🌱 Shasta daisies are extremely long-lived perennials that can thrive in the same location for 10-15 years or more with minimal division, though periodically dividing clumps every 3-4 years rejuvenates plants and improves blooming.
