    Ornamental Features

    Japanese Painted Fern's attractive ferny bipinnately compound leaves emerge deep purple in spring, turning silver in colour with showy burgundy variegation throughout the season. Neither the flowers nor the fruit are ornamentally significant. The deep purple stems are very colorful and add to the overall interest of the plant.

    Landscape Attributes

    Japanese Painted Fern is a dense herbaceous fern with a shapely form and gracefully arching fronds. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

    This is a relatively low maintenance plant, and usually looks its best without pruning, although it will tolerate pruning. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.

    Japanese Painted Fern is recommended for the following landscape applications;

    • Mass Planting
    • Border Edging
    • General Garden Use
    • Groundcover
    • Naturalizing And Woodland Gardens

    Planting & Growing

    Japanese Painted Fern will grow to be about 18 inches tall at maturity, with a spread of 24 inches. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 15 years.

    This plant does best in partial shade to shade. It prefers to grow in moist to wet soil, and will even tolerate some standing water. It is particular about its soil conditions, with a strong preference for rich, acidic soils. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone over the growing season to conserve soil moisture. This is a selected variety of a species not originally from North America, and parts of it are known to be toxic to humans and animals, so care should be exercised in planting it around children and pets. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
