Calendula officinalis has been treasured for centuries, and Zeolights carries forward that legacy with exceptional cold hardiness that extends the growing season well beyond what many annuals tolerate. The plant thrives in full sun conditions and adapts readily to a wide range of soil types, asking only for moderate water and soil pH between 6.0 and 7.5. Germinating quickly at soil temperatures between 68 and 85 degrees Fahrenheit, seeds establish themselves fast whether started indoors or direct sown outdoors, giving gardeners multiple pathways to success.
As a member of the Asteraceae family, calendula flowers serve ornamental purposes in garden beds, containers, and cut arrangements. The blooms add cheerful color to landscape plantings and work well as filler in mixed borders.
