General Description

The well-branched flossflower 'Pearl Blue' is a compact mounding plant that tends to flower earlier than others and certainly bears its lavender-blue to powdery blue blooms in profusion. This tender perennial is widely planted as a bedding annual and will bloom all season long.

The low, bushy plants have lush, deep green leaves. When temperatures are warm and growing conditions good, they produce big clusters of button-like flowers that are blue, white, or rose with silvery sheen on the petals. Bees and butterflies flock to the blooms. Deadheading will encourage vigorous flowering and keep plants looking pretty.

Vigorous and easy to grow, Pearl Blue flossflower performs best in sites with full sun and average to fertile loam with good drainage. Partial sun is tolerated in hottest regions but elsewhere full sun is usually best. Average water and regular fertilizer for flowering are recommended. Rarely bothered by deer, it's lovely in containers or mixed borders, as edging and pairs well with other brightly colored, sun-loving ornamentals. In tropical or subtropical zones these survive all year long as evergreen perennials although their flowering wanes in summer's intense heat. They may also self-sow if the growing season is long and mild.
