Japanese anemone ‘Splendens’

Anemone hupehensis var. japonica ‘Splendens’ (Japanese anemone ‘Splendens’) grow best in full-sun to part-shade, although too much shade can cause taller plants to become floppy if not otherwise supported. Plants attract many kinds of pollinators but are most attractive to honeybees and bumble bees.

Anemone hupehensis var. japonica ‘Splendens’ or Japanese anemone. Despite its common name, this member of the Ranunculaceae is actually native to China and considered naturalized in Japan for centuries. In its native and naturalized range, A. hupehensis var. japonica inhabits scrub lands, grassy slopes, and stream banks.

Anemone hupehensis var. japonica grows to 75 cm (2.5 ft) tall with a 45 cm (1.5 ft) spread. Japanese anemone grows well in soil of an average fertility and medium moisture, with some improvements in flowering when grown in slightly alkaline soils. The species and most cultivars grow in USDA Zones 4-8, with overwinter mulching helping plant survive winters in colder climates.

Individual plants under garden conditions can quickly form large, dense colonies. The root system of Japanese anemone is fibrous, but will produce prolific suckers. Plants should be installed in an area where either control of suckering can be managed or a large colony is desired.

‘Splendens’ produces spectacular pinkish-white to pale-rose flowers on multi-branched inflorescences from August to September/October. Plants attract many kinds of pollinators, but are most attractive to honeybees and bumble bees. At one time, Lurie Garden had three Japanese anemones in its plant palette–A. hupehensis var. japonica ‘Splendens’, A. hupehensis ‘Praecox’, and A. x hybrida ‘Honorine Jobert’. Currently, only ‘Splendens’ remains. Garden staff wonder if hybridization among the three cultivars promoted by the plethora of pollinators drawn to plants has resulted in introgression of the three cultivars into one color form.
