Tree Mallow

Lavatera trimestris. This annual, Mediterranean heirloom can be grown almost anywhere, although it prefers cooler, moist summers. A stunning, long-lasting cut-flower, Tree Mallow produces abundant cup- and trumpet-shaped, satiny blooms on long stems. Erect shrub-like plants produce many stems: cut entire stems with just two flowers in bloom: the additional buds will continue to open in bouquets that can last seven to twelve days. Terrific in display gardens paired with Salvia, Larkspur and Cosmos. Direct sow after all threat of frost has passed. Annual. Summer-flowering. Height: 24" to 36".

Average seed life: 3 years.

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".
