It prefers well-drained soil.
A sunny place is suitable from autumn to spring, and a cool, airy place in partial shade in summer.
For plants in the ground, it is good to plant them under deciduous trees.
For potted plants, water thoroughly when the soil surface dries; for plants in the ground, rainfall is sufficient unless summer brings a long spell of sunny weather and the soil becomes severely dry.
Apply slow-release fertilizer in spring when the shoots emerge and after flowering.
Pests and diseases include powdery mildew, rust, leaf miners, goldenrod lace bugs, spider mites and aphids.
