Lace Mantle is a new day length neutral variety bred to start blooming the first year from seed. Sweet Williams grow best in well drained, moist fertile soil. Plant them in full sun; in very hot summer areas, they will thrive with partial or light afternoon shade. Keep well-watered and feed several times during growing season. Cut when clusters of large florets are half open: buds open well in water and last for up to 10 days. After the first flush of bloom is over, cut back spent flower heads for rebloom.


In spring, 8 to 10 weeks before last expected frost date, sow seeds 1 inch apart in a container of seed starting mix. Cover very lightly, no more than 1/4 inch deep, and keep moist while awaiting germination. Provide a strong light source for seedlings until they are ready to plant outside. Once large enough to handle, transplant seedlings 2 to 3 inches apart into deeper containers or pots so root systems have room to develop. Feed every 2 weeks with half-strength fertilizer. When 3 to 4 inches tall, gradually acclimate to outdoor conditions and plant 12 inches apart in full sun in early spring after frost danger is over.
