German Madwort Plant Care

German Madwort (Asperugo procumbens) belongs to the Boraginaceae family within the Asperugo genus. German Madwort is native to Europe and temperate parts of Asia. German Madwort is also known as Climbing Madwort, Madwort.

German Madwort displays a low spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. German Madwort produces small blue star-shaped flowers in clusters.

Leaf size: approximately 1 inches.

Water a young or newly planted German Madwort every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

German Madwort thrives in full sun to partial shade.

Asperugo procumbens tolerates temperatures of 60–80°F. German Madwort prefers humidity levels of 40–60%.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for German Madwort to prevent waterlogging, which leads to root rot and fungal issues.

Feed German Madwort every 8 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to partial shade and well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

German Madwort is suited to USDA Zone 13a.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

German Madwort can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune German Madwort while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

German Madwort is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

German Madwort can be propagated through seeds, division of clumps.

German Madwort grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. German Madwort is native to Europe and temperate parts of Asia. In cooler regions, grow German Madwort as a houseplant or bring it indoors before the first frost.
