Why grow Carpet of Snow?

• Clusters of snow-white flowers with a honey-like fragrance.
• Low-growing, mat-forming habit for edging, groundcover, and container planting.
• Suitable for full sun to partial shade in well-drained soil.
• Flowers may begin approximately 9 weeks after sowing under suitable conditions.

Seed pack options

Choose from 1,000 seeds, 5,000 seeds, a 1/4 oz pack, or a 1 oz pack. This listing is for seeds, not live plants. Weight-based packs contain approximately 17,500 seeds per 1/4 oz or 70,000 seeds per ounce; actual counts vary.

Sowing instructions

• When to sow: Sow outdoors in early spring when hard freezes are no longer expected.
• Depth: Surface-sow and gently press seeds into the soil. Do not cover, as seeds need light to germinate.
• Moisture: Keep the seedbed evenly moist during germination.
• Temperature: The existing growing guidance recommends 55–75°F.
• Germination: Allow approximately 15–20 days; timing varies with conditions.
• Spacing: Thin seedlings to approximately 6 inches apart.

Growing and care

Choose full sun to partial shade and well-drained soil, with a suggested pH of 6.0–6.5. Water regularly while plants establish, and check container moisture often during warm weather. Lightly trim after the first flush of flowers to tidy the plants and encourage fresh growth and further blooming.

Growing in containers

Sweet Alyssum 'Carpet of Snow' makes a fragrant edging plant for patio pots, window boxes, and mixed containers. Position it near the rim so its spreading growth can soften the container edges.

• Container and mix: Choose a container with drainage holes and fill with a well-draining potting mix. Avoid leaving the pot standing in water.
• Sowing: Scatter seeds thinly over moist mix and gently press into the surface without covering. Keep moist until seedlings emerge, then thin to approximately 6 inches apart.
• Placement: Provide full sun to partial shade. In hot conditions, a position with afternoon shade can help protect plants from intense heat.
• Watering: Check moisture regularly, especially in warm or windy weather. Water when the surface begins to dry, allowing excess water to drain freely.
• Feeding: If the potting mix does not already contain fertilizer, use a fertilizer labeled for flowering container plants, following its directions. Avoid overfeeding.
• Flower care: Lightly trim after a flush of blooms to keep growth tidy and encourage fresh flowering.

Seasonal garden use

Grow as a cool-season annual for spring and summer color, with flowering dependent on local temperatures and care. Plants may self-sow in favorable mild-climate conditions. Use along borders, between taller flowers, or at container edges for a flowing white accent.
