Germination & Seedling
7-14 daysSeeds sprout and first true leaves emerge. Seedlings are delicate with rounded cotyledons visible.

Vegetative Growth
20-35 daysRosette develops characteristic white-tinged leaves in a tight, compact form. Plant establishes multiple leaf layers.
Maintain consistent watering and ensure adequate light to prevent bolting. Fertilize lightly every 2-3 weeks with balanced fertilizer. Mulch around base to retain moisture.
Rosette Formation

Harvest Tips
Begin harvesting outer leaves when plant is 4-6 inches tall, or cut entire rosette at soil level for a full harvest. Harvest in early morning for maximum crispness and water content. Cut with a sharp knife just above soil line. If harvesting outer leaves only, plant will continue producing for several weeks. Use immediately or store in refrigerator crisper for up to 2 weeks.
Fun Facts
- 🌱 Rosette White is an heirloom variety with origins in European seed catalogs, particularly valued in German and French gardening traditions for its delicate appearance and superior eating quality.
- 🌱 The white-tinged coloration of the outer leaves is a natural protective feature that develops in response to sunlight, making this variety more visually distinctive than plain green lettuces.
- 🌱 Lettuce is one of the few vegetables that actually becomes more tender and crisp as it ages (up to its harvest point), unlike most greens that deteriorate quickly after picking.
