    Description:

    This shrub or subshrub is primarily grown for its stunning iridescent purple foliage; leaves have contrasting black veins and a silver cast when mature; pinch stems to promote bushiness; best foliage color in part shade; can be overwintered indoors

    Ornamental Features

    Persian Shield's attractive large glossy pointy leaves emerge deep purple in spring, turning purple in colour with distinctive black veins and tinges of silver the rest of the year. It features dainty spikes of violet trumpet-shaped flowers rising above the foliage from late fall to late winter. The fruit is not ornamentally significant.

    Landscape Attributes

    Persian Shield is a multi-stemmed annual with an upright spreading habit of growth. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.

    This plant will require occasional maintenance and upkeep, and is best cleaned up in early spring before it resumes active growth for the season. It has no significant negative characteristics.

    Persian Shield is recommended for the following landscape applications;

    • Mass Planting
    • General Garden Use
    • Container Planting

    Planting & Growing

    Persian Shield will grow to be about 3 feet tall at maturity, with a spread of 3 feet. Although it's not a true annual, this fast-growing plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.

    This plant does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil pH, but grows best in rich soils. It is highly tolerant of urban pollution and will even thrive in inner city environments. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This species is not originally from North America. It can be propagated by cuttings.

    Persian Shield is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
