White Bouquet Ageratum is a compact flowering cultivar that produces masses of delicate white blooms from early summer through late fall. Growing 18 to 24 inches tall with a 12 to 18 inch spread, this heirloom variety reaches full flower in 84 to 91 days from seed and thrives in full sun across USDA zones 10 and 11. Deer leave it untouched, and its flowers attract pollinators throughout the warm months, making it a reliable choice for borders, containers, and cutting gardens.

Pure white pom-pom flowers appear continuously from June through November, creating a cloud-like effect in the garden that few other compact annuals can match. The plants stay naturally tidy and contained at 18 to 24 inches tall, eliminating the need for heavy deadheading. Unlike many ageratums, this variety tolerates moderate watering and moderate conditions without becoming leggy or stressed, and it remains resistant to deer browsing, a rare trait that makes it especially valuable in mixed plantings.
White Bouquet Ageratum is grown primarily as an ornamental flowering plant for garden beds, borders, and container plantings. The long-lasting white blooms work beautifully in cutting arrangements and as filler flowers to accompany other cut specimens. Many gardeners use it to add texture and continuous color to mixed summer containers, where its compact growth habit prevents it from overwhelming companion plantings.

Sow seeds indoors 6 to 8 weeks before your last frost date. Surface sow and press seeds in lightly, as they require light to germinate. Keep soil at 75°F until germination occurs (5 to 14 days), then reduce temperature to 60 to 65°F. Water from below by placing containers in a larger tray of water and allowing them to drain; this prevents damping off and avoids disturbing the tiny seeds.
Transplant outdoors about 1 to 2 weeks after your last frost, once soil has warmed and frost danger has passed. Space plants 1 inch apart. Harden off seedlings gradually before moving them to their final location.
Direct sow about 1 to 2 weeks after the last frost for flowers from mid-summer through fall. Surface sow and press seeds in lightly, keeping soil consistently moist until germination.
