Sneezeweed Autumn Lace is a cultivar of native North American wildflower known for its vibrant bicolored daisy-like flowers with red-orange petals and yellow centers, blooming prolifically in late summer through fall. This semi-dwarf variety typically reaches 24-30 inches tall, making it more manageable than the species.

Growth Stages

1

Seedling

2-3 weeks

Tiny plants with first true leaves appearing; very delicate at this stage with minimal foliage visible above soil.

Keep soil consistently moist but not waterlogged. Provide bright indirect light. Thin seedlings to proper spacing once 2-3 inches tall.

2

Vegetative Growth

4-6 weeks

Plant develops bushy mounding habit with fine, feathery foliage; stems lengthen and fill out. Height reaches 12-18 inches with dense branching.

Water regularly to encourage strong growth. Pinch back growing tips in late spring (before June 15) to promote bushier, more compact plants with more flowers. Stake if needed in windy locations.

3

Bud Formation

3-4 weeks

Compact flower buds appear at stem tips, gradually enlarging. Plant reaches full mature height of 24-30 inches. Foliage remains dark green and attractive.

Continue regular watering. Deadhead any early flowers to encourage more blooms. Apply balanced fertilizer or light compost top-dressing if soil is poor.

4

Flowering

8-12 weeks

Abundant daisy-like flowers with red-orange petals and bright yellow centers bloom profusely. Peak bloom occurs in late August through October, with flowers covering much of the plant.

Deadhead spent flowers regularly to extend bloom season and encourage more flowering. Provide water during dry periods. Support tall stems if needed. Enjoy as cut flowers.

5

Seed Maturation & Decline

Ongoing through winter

Flowers fade and form seed heads; stems and foliage may become darker or bronzed. Plant structure remains upright through winter.

Leave seed heads standing for wildlife and winter interest, or deadhead completely to prevent self-seeding. Cut back to ground level in early spring (March-April) before new growth emerges.

Harvest Tips

For cut flowers, harvest in early morning when stems are fully hydrated and flowers are newly opened. Cut stems at an angle just above a leaf node. Flowers last 7-10 days in a vase with fresh water. For seed collection, allow flower heads to dry completely on the plant (late October-November), then cut and collect seed heads in a paper bag. Plant fresh seeds in fall or stratify in moist cold for 30 days before spring planting.
