Tall Autumn Flowers for Zinnia Gap: Ageratum 'Blue Horizon'

Northern KY gardener cuts leggy, mildewy zinnias late August. Verbena/geraniums too weak alone. Needs tall (taller than geraniums), strong September–October blooms to grow among zinnias or transplant late August. Loves zinnias, won't replace.

Solution: Ageratum 'Blue Horizon'

  • Tall variety (20–30"), not common dwarf type.
  • Pinch first bloom before opening to encourage branching.
  • Great cut flower.
  • Peaks in Sept–Oct with beautiful blue flowers—stunning with geraniums and zinnias.
  • Easy from seed (Park Seed, Thompson & Morgan).

Fills the gap perfectly without replacing beloved zinnias.
