Rose Mallow Mix Seeds – Lavatera Annual Flowers

Large, Hibiscus-Like Flowers from Summer into Fall

Rose Mallow Mix (Lavatera trimestris), also known as tree mallow, fills sunny garden beds with generous, open flowers in shades of white, pink, rose, and lavender-pink. Its large, 4–5 inch blooms rise above bushy, shrub-like annual plants, bringing a soft wash of color to summer borders.

Plant a group where you can enjoy the flowers throughout the season. Despite its common name, tree mallow is grown here as an annual flowering plant, not a woody tree or perennial hibiscus.

Choose a Sunny Planting Site

Grow in full sun with well-drained sandy or loamy soil. Clay soil can be tolerated where drainage is adequate. The listed soil pH range is 6.0–8.0. Allow 18–24 inches between plants for their bushy growth.

How to Sow Rose Mallow Seeds

1. Direct sow outdoors after the last frost. Seedlings do not transplant well, so sowing in their final growing position is preferred.
2. Loosen the soil and sow groups of 3–4 seeds, spacing groups 18–24 inches apart.
3. Surface sow and cover with no more than 1/16 inch of soil. Light is required for germination.
4. Keep seeds consistently moist. At 65–80°F, germination typically takes 15–20 days.
5. Thin each group to the strongest seedling once plants are established.

Care for Continued Color

Water regularly and remove spent flowers to encourage continued blooming. Maintain good drainage while keeping plants supplied with moisture during active growth.
