Lithodora diffusa 'Grace Ward'

Grace Ward Lithodora is blanketed in stunning blue star-shaped flowers with white eyes at the ends of the stems from late spring to mid summer. Its small tomentose narrow leaves remain grayish green in colour throughout the year.

Grace Ward Lithodora will grow to be only 4 inches tall at maturity extending to 6 inches tall with the flowers, with a spread of 18 inches. Its foliage tends to remain low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years. As an evergreen perennial, this plant will typically keep its form and foliage year-round.

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 particular about its soil conditions, with a strong preference for sandy, acidic soils. It is somewhat tolerant of urban pollution. Consider covering it with a thick layer of mulch in winter to protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid. 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.

Grace Ward Lithodora is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
