General Description

Stellar™ Series flossflowers are known for improved summer heat tolerance, non-fading flowers and no need for deadheading (trimming off dead flower heads to encourage continued blooming). These tender perennials are widely planted as bedding annuals and will bloom all season long.

The compact bushy plants have lush, deep green leaves. When temperatures are warm and growing conditions good, they produce big clusters of button-like flowers that may be dusty purple, violet-blue or nearly white, depending on the cultivar. Bees and butterflies flock to the blooms. Old flowers on Stellar™ flossflowers naturally wither away and are overtaken by the newly opening blossoms.

Vigorous and easy to grow, flossflowers perform best in sites with full sun and average to fertile loam with good drainage. Partial sun is tolerated but full sun is best. Average water and regular fertilizer for flowering are recommended. Rarely bothered by deer, flossflowers are lovely in containers or mixed borders and pair well with other brightly colored, sun-loving ornamentals. In tropical or subtropical zones these survive all year long as evergreen perennials and develop shrubbier habits.
