Malva pusilla

Malva pusilla distribution

Malva pusilla, commonly known as the small mallow or little mallow, is a species of flowering plant in the Malvaceae family. This plant is native to Europe and Asia but has been introduced to many other parts of the world, including North America and Australia, where it is often considered a weed.

Description

Malva pusilla is an annual or biennial plant that typically grows to a height of 15-45 cm. The leaves are roundish, with 5–7 lobes, and are arranged alternately on the stem. The flowers are small, with a diameter of about 5 mm, and are pale pink or white in color. They have five petals and are borne in the leaf axils. The fruit is a disc-shaped schizocarp, which splits into several mericarps (segments) when mature.

Habitat and Distribution

Malva pusilla prefers habitats that are disturbed, such as fields, gardens, roadsides, and waste areas. It thrives in a variety of soil types but is commonly found in moist, nutrient-rich soils. As a cosmopolitan species, its distribution spans across temperate and subtropical regions worldwide.

Ecological Impact

While Malva pusilla is often regarded as a weed in many regions, it plays a role in the ecosystem by providing food for various insects and animals. However, its aggressive growth can outcompete native vegetation, leading to reduced biodiversity in some areas.

Uses

Historically, Malva pusilla has been used in traditional medicine to treat various ailments due to its anti-inflammatory and soothing properties. The leaves can be used in salads or as a cooked green, although it is not as commonly consumed as its relative, Malva sylvestris (common mallow).

Management

Control of Malva pusilla typically involves mechanical removal, such as hand-pulling or hoeing, before the plant sets seed. In agricultural or landscaped areas, herbicide application may be considered, though care must be taken to avoid impact on non-target species.

Taxonomy

The taxonomy of Malva pusilla has been subject to revision, and it has been known by several synonyms, including Malva rotundifolia. It belongs to the genus Malva, which comprises around 30 species of herbaceous plants.
