A small, dense shrub featuring soft, wooly round leaves paired along the stems; small, inconspicuous flowers in summer; very drought tolerant, great for rock gardens and raised beds
Grecian Horehound has attractive grayish green foliage with hints of silver which emerges white in spring. The small fuzzy round pinnately compound leaves are highly ornamental and remain grayish green throughout the winter. Neither the flowers nor the fruit are ornamentally significant.
Grecian Horehound is a dense multi-stemmed evergreen shrub with a mounded form. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.
This shrub will require occasional maintenance and upkeep, and can be pruned at anytime. It is a good choice for attracting bees and butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.
Grecian Horehound is recommended for the following landscape applications;
- Mass Planting
- Rock/Alpine Gardens
- General Garden Use
- Container Planting
Planting & Growing
Grecian Horehound will grow to be about 18 inches tall at maturity, with a spread of 3 feet. It has a low canopy. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years.
This shrub should only be grown in full sunlight. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is particular about its soil conditions, with a strong preference for poor, alkaline soils, and is able to handle environmental salt. It is somewhat tolerant of urban pollution. This species is not originally from North America. It can be propagated by division.
Grecian Horehound makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a canvas of foliage against which the thriller plants stand out. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
