Planting Instructions:

For best results, plant American Basketflower seeds in fall (August-November). These seeds require a natural cold stratification period to break dormancy, so fall planting allows them to experience winter conditions and germinate beautifully in spring. Simply scatter seeds in prepared soil and lightly cover.

Perfect for: Native plant gardens, wildflower meadows, pollinator gardens, and naturalized landscapes.

PLANTING INSTRUCTIONS:

• Fall planting is ideal, as seeds naturally undergo cold temperatures and dormancy during winter. In cold and temperate climates, sow seeds from September to November.  In warmer climates, seeds can be sown in late fall or winter.

1. Remove vegetation from the area to be planted and loosen the top few inches of soil. 
2. Add compost. 
3. Plant seeds  ½ inch deep.
4. Seedlings will emerge in the spring.  
5. Thin to 8 inches between plants.

• Spring planting:  American Basket Flower seeds can be direct sown in the spring.  

1. Remove vegetation from the area to be planted and loosen the top few inches of soil. 
2. Add compost.
3. Plant seeds  ½ inch deep.
4. Germination should occur within 7-21 days.
5. Keep the soil moist after sowing until plants are established.
6. Thin to 8 inches between plants.

• Indoor Planting:

1. To start indoors, plant three or four seeds 1/2" below the surface in individual peat pots or trays of good quality soil mix.
2. Keep soil moist (not wet or dry).
3. Germination should occur within 7-21 days.
4. Transplant outdoors when plants have true leaves and are 2-4 inches tall. 
5. Recommended spacing is 8 inches apart.

• Note: Plants may require support at first depending on their height.  

Site Selection:

• Prefers full sun (6+ hours of direct sunlight daily).
• Thrives in well-draining soils; sand, loam, clay.

Soil Preparation:

• No need to amend soil with fertilizer; American Basket Flower tolerates nutrient-poor conditions.

Watering:

• Once established, American Basket Flower is drought-tolerant.

Maintenance Tips:

• Mulch around plants to conserve moisture and suppress weeds.
• Avoid over-fertilizing; excess nutrients can reduce flowering.
• Deadhead spent flowers to promote continuous blooming and prevent aggressive self-seeding.
