In terms of cultivation, Actaea ‘White Pearl’ prefers partial to full shade; the recommended soil is moist, clayey. For Actaea ‘White Pearl’, regularly check the soil around the root ball: it should remain fresh.

The flowering (October) and spread of 50 cm will serve as benchmarks for distributing other plants around this plant.
