🌸 Lisianthus Seeds: The Star of Elegant Blooms

Lisianthus (Eustoma grandiflorum) is one of the most sought-after cut flowers due to its luxurious petals, upright stems, and two-to-three-week vase life.

Why growers love Lisianthus:

• 🌿 Professional florist quality blooms

• 🌸 Long vase life and strong stems

• 💐 Available in countless colors and double blooms

• 🌾 Profitable crop for cut flower markets

How to Start Lisianthus from Seed:

• Sow pelleted seeds directly in 200-cell trays.

• Maintain 70–75°F (21–24°C) for germination.

• Do not cover — Lisianthus requires light to germinate.

• Germination occurs in 10–15 days under bright light.

• Transplant when roots fill the plug tray, spacing 5–6 inches apart.

Pro Tip: Pinch Lisianthus after 6–8 leaves for branching, or leave unpinched for single long stems.

🔥 Celosia Seeds: Bold Texture & Color

Celosia adds fiery texture to bouquets with plume or cockscomb forms. Easy to start and fast to flower, it thrives in heat where Lisianthus slows down.

Start Celosia in plug trays 8–10 weeks before planting, then transplant outdoors once night temperatures remain above 60°F.
