General Description
Fluffy, white flowers bedeck the White Bouquet flossflower when temperatures are warm and growing conditions favorable. Though technically a tender perennial, this selection is widely grown as an annual bedding plant favored as a cutflower with its tall, sturdy, well-branched stems. 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 foliage of 'White Bouquet' is deep green, heart-shaped and has scalloped edges. Throughout the season it produces numerous clusters of fluffy, white flowers, Bees and butterflies pollinate the lightly fragrant blooms. The spent flowers should be removed to encourage continuous bloom and to keep the plants looking clean.
Flossflower is easily grown from seed and needs sites with full sun and average, moist soil with good drainage. Where summers are hot, 'White Bouquet' may flower best in locations with partial sun, or grown from fall to spring in tropical regions. This ornamental is rarely bothered by deer and has 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. They make great cutflowers, especially as dainy fillers; they may also self-sow.
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.
