Planting

Can plant in either early spring or early fall in an area that provides consistently moist soil. Add peat moss to the soil when planting. Water more frequently when first planted.

Soil

Grows well in damp soil, in marshy areas, and along water features. 

Light

Prefers shade to part shade. 

Care

If soil is nutrient-rich, no fertilizer is needed, but would benefit from a layer of compost each year.
