Lithodora planted in gardens reaches heights of only 6 to 10 inches (15-25 cm.), but a single plant can eventually spread 24 to 36 inches (61-91 cm.). Lithodora is relatively easy to find in garden centers. Otherwise, plant Lithodora seeds directly in the garden, or start them indoors a few weeks ahead of time. You can also propagate cuttings from established plants in mid- to late summer.
As for the care of Lithodora, water the plant regularly and don’t allow the soil to become bone dry. However, beware of overwatering and avoid soggy, waterlogged soil. In order to bloom properly, the plant requires partial sun to full sun in cool climate regions, and part shade or partial shade in hot regions, especially during the hottest part of the day. It prefers a Mediterranean-ish climate and doesn't thrive in hot, humid regions.
An ideal soil would be made up of 45% minerals (sand, clay, silt), 5 % organic (plant and animal) material, 25% air and 25% water. The mineral portion would be loam (20 – 30% clay, 30 – 50% silt and 30 – 50% sand).
Prune Lithodora lightly if it looks straggly, or if the leaves are damaged by winter cold. Remove any blackened leaves that could prevent new growth and possible disease. The plant can also be cut back after the flowering period ends in mid to late summer to maintain the desired size. Remove any unwanted tall or leggy growth. When pruning, use sharp garden shears.
Temperatures between 65 (18 °C) to 75 F (23 °C) and nighttime temperatures between 50 t(10°C) to 60 F (15 °C).
