Erodium moschatum aka Musk Stork's Bill

Musk stork's-bill is an easy, undemanding plant. It requires full sun and well-drained soil and tolerates drought as well as moderately moist conditions. It self-seeds freely in suitable habitats and needs little active management.

Musk stork's-bill grows as an annual or biennial herb, reaching 10–60 cm in height, with a sprawling to erect stem habit. Growth is typical for a weedy annual, completing its life cycle within one to two years.

Prefers light (sandy) to medium (loamy), well-drained soils with a neutral to mildly alkaline pH. Tolerates both dry and moderately moist conditions. Does not require fertile or specially prepared soil, thriving in disturbed and nutrient-poor ground.

Flowers are pale purple to pink or red, 7–15 mm long, with 5 petals and 10 stamens, arranged in umbels of 6–12 blooms. In UK conditions, bloom time is typically July to August. Fruits are distinctive, splitting into 5 sections each with a long beak (10–40 mm) resembling a heron's bill.

The bruised leaves emit a strong, characteristic scent of musk — the trait that gives the species both its common name and its specific epithet moschatum. The scent is released on contact and is noticeable throughout the growing season.

Musk stork's-bill is well suited to outdoor cultivation in USDA zones 5–9. It is native to Eurasia and North Africa and has naturalized widely, including throughout much of North America (northeast US, Pacific coast states, parts of Canada), New Zealand, and Australia. It favors disturbed, open ground such as meadows, fields, roadsides, and waste areas, and can become weedy where conditions suit it.

Musk stork's-bill propagates readily from seed. As an annual or biennial, it completes its life cycle in one to two seasons and self-seeds prolifically in disturbed habitats. Seeds ripen from August to September in UK conditions.

The leaves are edible raw or cooked and can be added to salads or used as a potherb. PFAF rates edibility at 2 out of 5. The species is considered edible similarly to the related Erodium cicutarium.

Musk stork's-bill has been used medicinally as an astringent and febrifuge. A tincture of the plant has been employed in the treatment of dysentery. PFAF rates medicinal utility at 1 out of 5.

A green dye can be extracted from the entire plant without requiring a mordant. PFAF rates other uses at 1 out of 5.

The flowers of musk stork's-bill attract insects, including midges and other small pollinators. The flower structure — 5 petals with 10 stamens — is typical of insect-pollinated Geraniaceae.

Known insect associates include the midge Dasineura erodiicola (which causes flower galls), moths, weevils, aphids, leaf miners, and root-feeding beetles. Fungal pathogens recorded on the plant include powdery mildews and rust.

The species has 19 documented synonyms in GBIF, including multiple infraspecific varieties such as var. australe, var. maculatum, var. praecox, and var. scissifolium. The basionym is Geranium cicutarium var. moschatum L.

Hardy in USDA zones 5–9 and UK hardiness zone 6, indicating tolerance of moderate frost. As an annual or biennial of Eurasian and North African origin, it is adapted to temperate climates and mild winters.

Musk Stork's Bill’s native range is Mediterranean areas and southwestern Europe, including Britain.

Musk Stork's Bill should be watered regularly, allowing the soil to dry out between waterings.

Musk Stork's Bill requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Muskus Grass will be sure to bring you many years of beauty and enjoyment.

Musk Stork's Bill is not known to cause harm to humans or pets.
