About Anemone × hybrida 'September Charm'

Anemone × hybrida 'September Charm' · also called September Charm Japanese anemone, pink single anemone · flowering

A graceful Japanese anemone bearing single, soft silvery-pink flowers with golden-yellow centres on tall, wiry stems from late summer well into autumn. It forms spreading clumps of dark, vine-like foliage and lights up shady and partly sunny borders when little else blooms. Once established it spreads steadily by runners and is reliably hardy.

Mature size: 75-120 cm tall in flower, spreading 45-60 cm and wider over time.

Indoor size vs how big it gets in the wild

Anemone × hybrida 'September Charm' is a garden shrub whose final size is set more by your secateurs than by the plant — pruning, not luck, decides how big it gets. Indoors and in a pot, expect 75-120 cm tall in flower, spreading 45-60 cm and wider over time.. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

Left unpruned it builds a woody framework that gets taller and wider every year; with annual pruning you hold it at whatever size suits the space.

Remove the oldest, thickest stems at the base each year to keep it open and within bounds.
Growing it in a large container rather than open ground naturally restricts the ultimate size.
