Seed Germination
14-21 daysSeeds require cold stratification and light exposure. Small seedlings emerge with narrow cotyledons.
Stratify seeds in moist sand for 4-6 weeks in refrigerator. Keep soil moist but not wet. Provide bright light once germinated.
Seedling & Rosette Formation
6-8 weeksDevelops basal rosette of finely divided, feathery foliage close to the ground. Leaves are narrow and fern-like.
Thin to proper spacing early. Avoid overwatering. Maintain bright light. No fertilization needed.
Vegetative Growth
4-8 weeksStems elongate, becoming tall and somewhat spindly (18-30 inches). Foliage remains sparse and delicate.
Allow to dry between waterings. Can support with stakes if needed. Do not fertilize.
Flowering
8-12 weeks (peak bloom June-September)Produces distinctive red and yellow bicolor flowers with dark central columns. Blooms are 1-2 inches across, appearing in succession on multiple stems.
Deadhead spent flowers to encourage more blooms. Reduce watering in humid climates to prevent stem rot.
Seed Maturation & Decline
4-6 weeksFlowers fade to brown seed heads with prominent central cones. Plant may decline after seed set.
Leave seed heads for birds and self-seeding. Allow seeds to mature fully before removing. Plant is often short-lived after this stage.

Harvest Tips
Cut flowers when fully open for fresh arrangements (they last 5-7 days in water). For seed collection, allow flowers to dry on the plant until seed heads are brown and hard (late August-September). Cut seed heads and dry indoors, then thresh to collect seeds. Scatter fresh seeds in fall for spring germination, or store dry seeds in cool, dry location.
