Dwarf Blue Mink Ageratum is a compact annual flower that brings exotic, globe-shaped blooms in a striking blue to any garden space. Native to the tropics of Central America and Mexico, this cultivar grows just 8 to 12 inches tall, making it ideal for edging flowerbeds, rock gardens, or container displays. Reaching maturity in 70 to 79 days, it rewards gardeners with continuous flowering throughout the season in zones 10 to 11, or as a tender annual in cooler climates.

The globe-shaped flower heads of Dwarf Blue Mink are genuinely distinctive, with an exotic quality that sets them apart from typical garden asters. Its compact, mounding habit means you get a dense profusion of blooms without constant deadheading, while the plant's ability to thrive in full sun and moderate water makes it low-maintenance once established. This open-pollinated variety is frost-tender but seasons itself quickly, flowering reliably within about 75 days from sowing.
Dwarf Blue Mink Ageratum is grown exclusively as an ornamental flower. Its compact size and prolific blooming habit make it valuable for edging beds, filling gaps in rock gardens, and creating cohesive color displays in containers and window boxes. The globe-shaped flower heads add textural interest and an unusual quality to mixed annual plantings where gardeners want something more distinctive than conventional bedding annuals.

Start seeds indoors 6 to 8 weeks before your last spring frost date. Maintain soil temperature between 70 and 75 degrees Fahrenheit for reliable germination. Keep the seed-starting mix consistently moist but not waterlogged until seedlings emerge.
Harden off seedlings gradually over 7 to 10 days by exposing them to increasing amounts of outdoor light and air movement. Transplant outdoors after all frost danger has passed and soil has warmed. Space plants 10 inches apart in beds or containers with full sun exposure.
Pinch seedlings when they develop their first true leaves to encourage branching and a more compact, mounding form. Light deadheading of spent flowers will promote continuous blooming, though this variety is relatively self-cleaning and doesn't strictly require it.
