The Authority in Flower Seeds

Every great bloom begins with a single seed — and at Trailing Petunia, we’ve built our entire brand around making sure that seed performs perfectly.

Why Flower Seeds Still Rule the Greenhouse

With modern hybrids and pelleted seed technology, today’s flower seeds rival vegetative cuttings for vigor and uniformity.
They give growers flexible scheduling, disease-free starts, and unmatched color options — all at a fraction of the cost of plugs or rooted liners.

Advantages of seed-grown production:

  • Predictable germination and crop timing

  • Uniform growth habits and flowering windows

  • Easier storage and transport

  • Broader variety selection

  • Long-term cost efficiency

Flower seeds like Verbena, Lisianthus, Bacopa, and Wave Petunia deliver the consistency, vigor, and profitability that professional growers need to thrive.
