Lavatera trimestris is a popular heirloom flower that blooms in mid summer. This lovely mix includes various shades of pink, rose and white. Lavatera is usually combined with cleome in cottage gardens.
Lavatera trimestris often reseeds, but I like to sow new seeds each year because self sowing is unreliable here in zone 5.
Sowing Lavatera trimestris Seeds:
Sow indoors 6-8 weeks before the last frost date. Or sow outdoors after the
last frost. Barely cover the seeds. Full sun. Spacing 12".
