Growing Tips

  • Start seeds indoors or sow outdoors after severe frost has passed.
  • Choose a sunny location with sturdy support for climbing growth.
  • Keep the seed-starting medium lightly moist without creating soggy conditions.
  • Give mature vines plenty of room because trumpet vine can spread vigorously.

Seed Storage

Store unused seeds in a cool, dry, dark location. Keep them sealed in their original packet or an airtight container away from moisture, heat, and direct sunlight.

Important Growing Note

Campsis radicans is a vigorous perennial vine that can spread beyond its original planting area under favorable conditions. Provide sturdy support and adequate space, and check local recommendations before planting because trumpet vine can be invasive in some regions.

The yellow flower color may also vary depending on the specific seed line. Seed-grown plants can show natural variation in flower color, growth habit, and flowering time.

Unique Facts About Seeds

  • Campsis radicans is commonly known as trumpet vine because of its distinctive trumpet-shaped flowers.
  • The plant develops woody stems that can climb using aerial rootlets.
  • Mature vines can create substantial vertical coverage when given suitable support.
  • Trumpet-shaped flowers can be attractive to hummingbirds and other nectar-feeding pollinators.

Growing Instructions

Planting Season: Sow seeds in spring after the danger of severe frost has passed. In suitable climates, seeds may also be started indoors before outdoor planting.

Sowing: Use a loose, well-drained seed-starting mix. Sow the seeds and cover them lightly with growing medium.

Depth: Plant seeds approximately ¼ inch deep.

Spacing: Provide several feet of space between young plants when growing them in the landscape, especially near fences, trellises, or other permanent supports.

Sunlight: Provide full sun for the best flowering. Partial shade can be tolerated, although reduced sunlight may result in fewer flowers.

Soil: Grow in fertile, well-drained soil. Trumpet vine can tolerate a range of soil conditions once established, provided drainage is adequate.

Watering: Keep soil evenly moist during germination and early seedling growth. Once established, water deeply when the soil begins to dry.

Germination: Seeds commonly germinate within approximately two to four weeks under favorable conditions. Temperature and moisture can affect germination speed.

Transplanting: Harden seedlings gradually before moving them outdoors. Transplant young plants carefully after frost danger has passed.

Fertilizing: Established plants generally require little fertilizer when grown in reasonably fertile soil. Avoid excessive nitrogen, which can encourage vigorous foliage at the expense of flowering.

Care: Provide a strong trellis, arbor, fence, or other support. Keep young plants weed-free and guide new stems toward the support as they begin climbing.

Flowering/Maturity: Seed-grown plants may take several growing seasons to reach flowering size. Established vines generally produce trumpet-shaped flowers during the warmer months.

Pruning: Prune established vines during dormancy or according to local growing conditions. Remove unwanted growth and maintain the vine within its intended garden area.
