Flower Seeds: The Core of Professional Greenhouse Production

Every commercial greenhouse program starts with one essential ingredient — high-quality flower seeds. These tiny powerhouses determine plant vigor, uniformity, bloom timing, and even color quality.

At Trailing Petunia, we specialize in professional-grade flower seeds chosen for their consistency, germination strength, and retail-ready performance.

Our grower-tested favorites — Verbena Seeds, Lisianthus Seeds, and Bacopa Seeds — represent three powerful categories: trailing, cut flower, and companion crop production.

These crops form the backbone of any profitable flower seed greenhouse program.

Professional Plug Production: The Foundation of Flower Success

Perfect plugs mean perfect crops.
Flower seeds must be handled with precision in moisture, light, and temperature from day one.

Stage Temperature Light Moisture pH Duration
Germination 70–75°F Light optional Level 3 5.6–5.9 5–10 days
Early Growth 68–72°F Bright indirect Level 3–4 5.8–6.2 7–14 days
Rooting 68°F High light Level 2–3 5.8–6.2 10–20 days
Finishing 65–70°F Full light Level 2 5.8–6.4 Varies by crop

Balanced nutrition, humidity control, and airflow prevent stretch and disease — especially in species like Bacopa and Verbena.

Lighting, Fertility & Growth Regulation

All three crops — Verbena, Lisianthus, and Bacopa — perform best under high light and balanced fertility.

Lighting:

  • Maintain 12–14 hours/day or use night interruption lighting.

  • DLI target: 12–14 mols/day.

Fertility:

  • Use 20-10-20 alternating with calcium nitrate.

  • Maintain EC around 1.5–2.0 mS/cm for finishing.

PGRs:

  • Bonzi® drench: 1–3 ppm for Verbena.

  • B-Nine® spray: 2,500–4,000 ppm for compact Bacopa.

  • Lisianthus: Generally not needed if grown cool and bright.

These methods ensure tight internodes, strong stems, and vivid bloom color across all flower seed types.
