Shasta Daisy (Leucanthemum × superbum) is a classic perennial flowering plant beloved by gardeners worldwide for its cheerful, bright appearance. It was developed in the late 19th century by American horticulturist Luther Burbank, who crossbred several daisy species to create this iconic bloom.
The flower is instantly recognizable by its crisp white petals surrounding a bold yellow center disc. It typically grows between 2 to 3 feet tall, making it an excellent mid-border plant in garden beds. Some varieties can grow even taller, while dwarf cultivars stay compact and tidy.
Shasta Daisies are hardy perennials that thrive in USDA zones 4 through 9, meaning they can survive cold winters and return reliably each spring. They are known for their long blooming season, typically flowering from early summer through early fall, providing months of garden color.
Beyond their beauty, Shasta Daisies are highly valued for attracting pollinators. Bees, butterflies, and other beneficial insects are drawn to their open, accessible blooms. They also make wonderful cut flowers, lasting well in vases and brightening up indoor spaces.
The plant is remarkably versatile and low-maintenance, tolerating a range of soil conditions as long as drainage is adequate. It thrives in full sun but can manage in partial shade, though flowering may be reduced. Its adaptability makes it a favorite among beginner and experienced gardeners alike.
There are many popular cultivars available today, including ‘Becky,’ ‘Alaska,’ ‘Snowcap,’ and ‘Silver Princess,’ each offering slight variations in height, bloom size, and petal form. Some varieties feature double or frilly petals, adding texture and visual interest to garden designs.

How To Grow Shasta Daisy From Seed
1. Start Shasta Daisy seeds indoors about 6 to 8 weeks before the last expected frost date in your area. This gives seedlings a strong head start before being transplanted outside.
2. Use a good-quality, well-draining seed-starting mix rather than regular garden soil. A lightweight mix ensures proper aeration and moisture retention, which is critical for germination success.
3. Fill small seed trays or individual cell pots with the moistened seed-starting mix. Gently firm the surface so it is even, but avoid compacting the medium too tightly.
4. Sow seeds on the surface of the mix and press them down very lightly. Shasta Daisy seeds need light to germinate, so do not cover them with soil — simply press them into contact with the surface.
5. Mist the surface gently with a spray bottle to avoid displacing the tiny seeds. Keeping moisture consistent during this early stage is essential for triggering germination.
6. Cover the tray loosely with a clear plastic lid or plastic wrap to retain humidity. Place it in a warm location where temperatures stay around 70°F (21°C) for best results.
7. Germination typically occurs within 10 to 20 days. Check the trays daily and remove the plastic cover as soon as you see sprouts emerging to prevent damping off disease.
8. Once sprouted, move seedlings to a bright location — ideally under grow lights for 14 to 16 hours per day, or on a south-facing windowsill. Strong light prevents leggy, weak growth.
9. Water seedlings carefully from below by placing the tray in a shallow dish of water. This encourages roots to grow downward and prevents overwatering the delicate stems.
10. When seedlings develop their first true leaves, thin them out so only the strongest plant remains in each cell. Overcrowding leads to poor air circulation and weak plants.
11. Begin fertilizing lightly with a diluted balanced liquid fertilizer once the first true leaves appear. Feed every two weeks to support healthy, steady growth without overwhelming the young plants.
12. About one to two weeks before transplanting outdoors, begin hardening off the seedlings. Place them outside in a sheltered spot for a few hours each day, gradually increasing their outdoor exposure.
13. Transplant seedlings outdoors after all danger of frost has passed. Choose a site that receives full sun — at least 6 hours of direct sunlight daily — for the best blooming performance.
14. Prepare the planting bed by loosening the soil and incorporating compost for added nutrients. Shasta Daisies prefer slightly fertile, well-draining soil with a neutral to slightly acidic pH.
15. Space transplants about 18 to 24 inches apart to allow for mature spread and good airflow between plants. Proper spacing reduces the risk of fungal diseases and encourages fuller growth.
16. Water newly transplanted seedlings deeply and consistently for the first few weeks while they establish their root system. Once established, Shasta Daisies are relatively drought-tolerant and require less frequent watering.
