Germination
7-10 daysSeeds sprouting and first true leaves emerging. Seedlings are delicate with cotyledons visible.
Keep soil evenly moist. Maintain cool temperatures (60-70°F). Provide bright light but avoid direct intense heat.
Seedling establishment
2-3 weeksDevelopment of first and second sets of true leaves. Small rosette forming with characteristic oak-like leaf shape beginning to show.
Thin seedlings to proper spacing if direct seeded. Provide consistent moisture and moderate fertilizer. Maintain cool conditions.
Vegetative growth
3-4 weeksRapid expansion of leaf rosette with increasingly frilled golden-yellow leaves. Plant develops its characteristic appearance with delicate, lacey foliage.
Continue regular watering. Apply balanced fertilizer every 2-3 weeks. Mulch to retain moisture and cool roots. Monitor for bolting signals in warm weather.
Baby leaf harvest
2-3 weeksYoung, tender leaves at harvestable size (4-6 inches long) while plant maintains actively growing outer leaves.
Begin harvesting outer leaves once they reach desired size. This encourages continued production from the center. Keep picking to delay bolting.
Full maturity/harvest ready
until bolting or frostFull-sized rosette with abundant golden-yellow, deeply frilled leaves ready for complete harvest. Plant may show early bolting signals (lengthening center stem) in warm conditions.
Harvest entire plant by cutting at soil level or harvest individual outer leaves. Use quickly after cutting for best flavor. Pull plant if bolting begins.

Harvest Tips
Harvest baby leaves when 4-6 inches long for tender, mild flavor, or allow full maturity for larger leaves. Begin harvesting outer leaves first, allowing the center to continue growing for an extended harvest. Cut or pinch leaves in the morning after dew dries for best quality. Roc d'Or is extremely cold-hardy and actual flavor improves after light frosts. Harvest before temperatures exceed 75°F regularly, as bolting accelerates in heat. Entire plant can be cut at soil level when ready, or use the cut-and-come-again method for continuous picking.
Fun Facts
- 🌱 Roc d'Or is a French heirloom lettuce variety with a name meaning 'Rock of Gold,' referring to both its golden-yellow coloring and sturdy cold-hardiness—it can tolerate light frosts better than most lettuce varieties.
- 🌱 The oak leaf type of lettuce, to which Roc d'Or belongs, gets its name from the distinctive deeply lobed and frilled leaves that resemble oak tree leaves, making it one of the most visually distinctive loose-leaf lettuce types.
- 🌱 Unlike head lettuces, loose-leaf varieties like Roc d'Or use a cut-and-come-again harvesting method, allowing gardeners to harvest outer leaves continuously while the plant regrows from the center, extending the harvest season significantly.
