General Description
Fluffy, cool lavender to violet-blue flowers bedeck Cloud Nine™ Blue flossflower ('Balclinebu')when temperatures are not hot and growing conditions favorable. Though technically a tender perennial, flossflower is widely grown as an annual bedding plant. It is native to Mexico and Central America where it grows as an evergreen subshrub with a dense, bushy habit, but it has also become naturalized in tropical and subtropical countries across the globe. The Cloud Nine Series was developed by Ball Horticultural Company and are propagated by cuttings.
The fragrant foliage is deep medium green, heart-shaped and has scalloped edges. Throughout the season, as long as it is not too hot, a plant produces numerous clusters of fluffy, spidery flowers of pale blue-violet to lavender. Bees and butterflies pollinate the lightly fragrant flowers. The spent blooms should be removed to encourage continuous bloom and to keep the plants looking clean.
Flossflower is easily grown and excels in garden sites with full sun and average soil with moisture and good drainage. Where summers are hot, Cloud Nine™ Blue's foliage can wither and flowering cease. Thus, plants may flower more continually in locations with partial sun. These ornamental are rarely bothered by deer and have few pest and disease problems. Enjoyed as a colorful bedding plant since the Victorian times, flossflower looks best in containers or mixed borders with other brightly colored, sun-loving ornamentals. In tropical regions the plants can be evergreen perennials and have their best flowering performance in the comfortable dry season.
Unfortunately, Ageratum houstonianum has escaped from cultivation in many frost-free regions globally and is considered a problematic, invasive weed-—especially because its foliage is toxic to grazing ruminants.
