Life History
Garlic mustard is a cool-season obligate biennial herb. Seeds germinate in early spring (April-May) of the first year resulting in initially high seedling densities. Natural mortality during the first year results in only 2%-4% of the plants surviving to flower the following spring. Garlic mustard is self- or cross-pollinated and a single plant can populate an entire site. Adult plants set and disperse seed in late spring (May-June) the second year and produce an average of 165-868 seeds. The seeds are dormant for 20 months germinating in early spring of year four.

It is hardy to zone 0 and is not frost tender. It is in flower from April to June, and the seeds ripen from June to August. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, flies, Lepidoptera (Moths & Butterflies). The plant is self-fertile. It is noted for attracting wildlife.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in full shade (deep woodland) or semi-shade (light woodland). It requires moist or wet soil.

Cultivation :-
Prefers a damp rich alluvial soil. Succeeds in damp shady places where few other herbs will grow. A good woodland edge plant, it also grows well in the bottom of hedgerows and will self-sow freely in suitable conditions. On a calm day the plant emits a strong smell of garlic. This is especially pronounced if the leaves are bruised. This species is an important food source for the orange-tip butterfly.

Seed – sow outdoors in situ either in spring or autumn.
