Seedling
6-12 monthsYoung plants emerge with simple leaves and develop slowly. Initial growth is modest during first year.
Keep soil consistently moist. Protect from direct sun and strong winds. Be patient—seedlings develop slowly.
Juvenile/Establishment
12-24 monthsPlant develops its characteristic deeply lobed foliage and establishes a strong root system. Growth accelerates in year two.
Maintain consistent moisture. Apply 2-3 inches of mulch around base. No fertilizer needed if soil is amended.
Vegetative
Year 2 onwards (winter)Mature foliage is fully formed—dark green, finely divided leaves create an ornamental mounding habit. Plant reaches full size.
Water during dry spells. Remove any dead foliage in spring. Plant is generally low-maintenance.
Flowering
December-March (6-8 weeks)Nodding clusters of bell-shaped flowers appear, typically pale greenish-yellow with purple or maroon edges. Flowers are long-lasting and appear in late winter to early spring.
Flowers require cool temperatures to develop fully. Do not deadhead if you want self-seeding. Enjoy the ornamental effect.
Seed Development & Dispersal
March-JuneAfter flowering, seed pods develop and mature. Seeds mature and drop, with seedlings appearing nearby in favorable conditions.
Allow flowers to remain on plant if self-seeding is desired. Seedlings will appear in spring; thin or relocate as needed.
