Establishment (Year 1)
4-6 monthsPlant develops a root system and basal foliage clump with lobed, deeply cut leaves. Little to no flowering.
Keep soil consistently moist. Mulch around the base. Deadhead any early flower buds to encourage root development. Fertilize lightly with balanced fertilizer.
Vegetative Growth (Early Summer)
May-JuneDense mounding habit develops with multiple stems emerging. Foliage is lush, deeply lobed, and green. Plant reaches 12-18 inches.
Water regularly. Apply balanced fertilizer in spring as growth begins. Monitor for slugs and spider mites. Stake if in exposed locations.
Flowering (Late Summer to Fall)
August-OctoberTall, branching stems (2-3 feet) emerge with semi-double deep pink flowers at the top. Dark burgundy center stamens are visible. Multiple blooms open progressively.
Deadhead spent flowers to encourage continued blooming. Water consistently during this stage. Stake tall stems if needed. High phosphorus fertilizer supports flowering.
Seed Development & Dormancy (Late Fall to Winter)
October-MarchFlowers fade and seed heads develop. Foliage yellows and dies back. Plant enters winter dormancy with underground rhizomes intact.
Leave seed heads for visual interest and wildlife benefit. Cut back dead foliage in late fall or early spring. Apply winter mulch (3-4 inches) in colder zones. Do not disturb dormant crowns.
Division & Rejuvenation (Spring)
March-AprilNew shoots begin emerging from the soil in early spring as temperatures warm. Colonies can be divided at this stage.
Divide established plants (3+ years old) in early spring before new growth. Each division should have 2-3 growth buds. Replant divisions at the same depth and water in well.

Fun Facts
- 🌱 Japanese anemones are not native to Japan but to China; they were extensively cultivated and refined in Japanese gardens, hence the common name.
- 🌱 Pamina is a hybrid cultivar, the result of crossing Anemone vitifolia with Anemone tomentosa, creating more robust plants than either parent alone.
- 🌱 The deep pink 'Pamina' cultivar was developed in Europe and is sometimes called 'Pamela' in older literature; it remains one of the most popular dark pink selections for fall gardens.
