Seed Treatment:
• Scarification: Gently nick the seed coat with a nail file or soak seeds in warm water for 12–24 hours before planting.
When to Sow:
• Indoors: Start seeds 6–8 weeks before the last expected frost.
• Outdoors: Sow after all danger of frost has passed and soil has warmed (minimum 65°F / 18°C).
Sowing Instructions:
• Sow seeds ¼ inch (6 mm) deep in a moist, well-draining seed-starting mix.
• Keep soil consistently moist but not soggy.
• Maintain temperature at 70–75°F (21–24°C).
• Germination usually occurs in 10–20 days.
Light Requirements:
• Requires full sun (6+ hours of direct sunlight daily).
• Performs best in a warm, sunny location.
Soil Requirements:
• Prefers well-draining, fertile soil enriched with compost.
• pH range: 6.0–7.5.
Watering:
• Water regularly during germination and early growth.
• Once established, water moderately—allow soil to dry slightly between waterings.
Spacing:
• Space plants 12–18 inches (30–45 cm) apart.
Growing Tips:
• A fast-growing climbing annual vine with striking red, orange, yellow, and cream-colored flowers that bloom in cascading sprays.
• Provide support or a trellis for vertical growth.
• Perfect for fences, arches, and garden screens.
• Attracts hummingbirds and pollinators.
• Grows as an annual in most zones, but can be perennial in USDA Zones 9–11.
