Germination & Seedling
10-14 daysTiny seedlings emerge with feathery cotyledons. Plant is very delicate and low-growing.
Keep soil consistently moist but not waterlogged. Thin seedlings to proper spacing once 2-3 inches tall. Protect from strong winds.
Vegetative Growth
3-4 weeksPlant develops delicate, finely divided feathery foliage. Stems are thin and branching; height reaches 12-18 inches.
Minimal fertilizer needed; avoid over-feeding. Water moderately. Support with stakes if in windy locations.
Flowering
3-4 weeksDelicate blue, purple, pink, or white flowers appear at branch tips on thin stems. Flowers are intricate and decorative.
Continue moderate watering. Avoid heavy nitrogen fertilizer which promotes foliage over flowers. Flowers attract beneficial insects.
Seed Pod Development
4-5 weeksFlowers fade and characteristic inflated seed pods form, resembling tiny balloons. Pods begin as green, gradually turning brown.
Reduce watering slightly. Allow pods to mature and dry on the plant. Stop fertilizing.
Seed Maturity & Harvest
2-3 weeksPods dry completely and turn brown; seeds inside are black and hard. Plant begins to desiccate naturally.
Allow complete drying before harvest. Pods can be cut and dried indoors if rain threatens. Seeds are ready when pods papery and seeds black.

Harvest Tips
Harvest seed pods when completely dry and brown, typically 4-5 months after planting. Cut stems with mature pods and hang upside down in a dry, warm location to finish drying. Once fully dry, rub pods between hands to release seeds. Alternatively, allow pods to naturally shatter on mature, standing plants and collect fallen seeds.
