Budding
1-2 weeksFlower buds begin forming at the tips of stems, appearing as small, tight clusters above the foliage.
Maintain consistent moisture. Deadhead spent buds to encourage continuous blooming. Reduce watering slightly if in wet conditions.
Flowering
6-12 weeks (can extend throughout summer)Delicate, fringed flowers bloom in pink, red, or white with characteristic dark eyes. Flowers appear in succession over many weeks.
Deadhead regularly to promote prolonged blooming. Reduce fertilizer to avoid excessive foliage at the expense of flowers. Maintain moderate water.
Seed Set & Dormancy
Variable; varies by climateAs temperatures cool in fall, flowering diminishes. Plants can be left to self-seed or cut back for tidiness.
Allow some flowers to set seed for self-propagation if desired. Cut back dead growth in late fall or early spring. Mulch lightly in cold zones if needed.
