Trimestris Mix Lavatera Seeds

Trimestris Mix (Lavatera trimestris) is a beautiful blend of classic annual Rose Mallows that fills the garden with an abundance of large, silky blooms in shades of pure white, blush pink, soft rose, bright pink, and rich crimson. Often compared to miniature hollyhocks or hardy hibiscus, these elegant flowers bloom continuously from early summer until frost, creating a spectacular display of old-fashioned cottage garden charm. The upright, well-branched plants quickly develop into colorful flowering shrubs that provide months of effortless beauty while attracting butterflies, bees, and other beneficial pollinators.

Fast-growing and remarkably easy to cultivate, Trimestris Mix reaches 24 to 36 inches in height, producing hundreds of satiny blossoms over an exceptionally long blooming season. The attractive gray-green foliage provides a perfect backdrop for the colorful flowers, while the long stems make excellent cut flowers for fresh bouquets. Whether planted in drifts, borders, or cutting gardens, this colorful mixture offers a constantly changing display of elegant blooms throughout the growing season.

Garden Uses

Trimestris Mix is an excellent choice for cottage gardens, cutting gardens, annual borders, pollinator gardens, wildflower meadows, and mixed flower beds. Large group plantings create clouds of soft pastel and vibrant color, while individual plants add height and elegance to sunny borders.

The colorful blooms combine beautifully with larkspur, cosmos, bachelor's buttons, zinnias, snapdragons, delphiniums, foxgloves, salvia, coreopsis, and ornamental grasses. The sturdy stems produce outstanding fresh-cut flowers that remain attractive in arrangements for several days.

Growing Information

Trimestris Mix grows best in full sun and well-drained, moderately fertile soil. Plants tolerate average garden conditions and perform well during warm summer weather with only moderate watering. Mature plants generally reach 24 to 36 inches tall with a spread of 18 to 24 inches.

Sow seeds directly outdoors after danger of frost has passed or start indoors 4 to 6 weeks before the final spring frost. Plant seeds approximately ¼ inch deep and maintain temperatures between 65 and 70°F. Germination usually occurs within 10 to 14 days.

Water regularly while plants become established, then provide moderate irrigation during prolonged dry periods. Removing spent flowers encourages continuous blooming until frost. Taller plants growing in exposed locations may benefit from light staking.
