Days to Germination: 7-20 days
Lavatera trimestris. A Mediterranean heirloom, it can be grown almost anywhere, although it prefers cooler, moist summers. Sensitive to root disturbance, it is best sown directly in the garden after all danger of frost has passed. Direct-sow 1⁄4" to 1⁄2" deep in rich, fertile and well-draining soil and full sun. Tamp down and keep the seedbed moist until seedlings emerge. If your season is short, you can start it indoors in peat pots 6 to 8 weeks before transplanting. When seedlings are 4" tall, harden them off by gradually acclimating them to the outdoors over 7 to 10 days. Thin plants to 18" to 24" apart. Provide consistent moisture. A long-lasting cut flower in white, silver, pink, pink with deep rose veins or mixed, Lavatera produces abundant trumpet-shaped, satiny blooms on long stems. Summer flowering. Height: 24" to 36".
