- Toxicity
To humans
The plant known as Allium insubricum, commonly referred to as the wild onion, is not generally considered toxic to humans. However, it is important to note that members of the Allium family can cause unpleasant reactions in some individuals when consumed in large quantities or if someone has a sensitivity to this group of plants. Symptoms of such a sensitivity may include gastrointestinal distress such as nausea, vomiting, and diarrhea. More severe reactions, while rare, could occur in individuals with a particular allergy to this type of plant.
To pets
Allium insubricum, or the wild onion, is toxic to pets, particularly cats and dogs. Members of the Allium genus, including onions, garlic, leeks, and chives, contain compounds known as thiosulfates which can be harmful to pets if ingested. Symptoms of Allium toxicity in pets include gastrointestinal upset like vomiting and diarrhea, as well as more serious conditions such as lethargy, abdominal pain, and an elevated heart rate. One of the most dangerous consequences is the potential for oxidative damage to red blood cells, leading to hemolytic anemia. If a pet ingests this plant, prompt veterinary attention is crucial.

- Water
The Lombardy garlic needs to be watered regularly to maintain moist soil, particularly during the growth and blooming periods. Water the plant deeply once a week, providing about 1-2 gallons depending on the size of the plant and the weather conditions. During hot, dry spells, you may need to water the Lombardy garlic twice a week, ensuring that the water penetrates to the roots without causing waterlogging. Reduce watering after the blooming period as the plant enters dormancy.
- Light
Lombardy garlic thrives in full sun, so it's best to position it in a spot where it can receive at least 6 hours of direct sunlight daily. Ensure that it's planted in an area with bright, unfiltered sunlight to promote healthy growth and vibrant blooms.
- Temperature
Lombardy garlic prefers temperate climates and can survive minimum temperatures down to about 20°F. The plant's ideal temperature range for vigorous growth is between 60°F and 70°F. It is important to protect it from temperatures below 20°F to prevent freezing damage.
- Pruning
Pruning Lombardy garlic is not often necessary but can be done to remove spent flower stalks and tidy up the plant. Prune back foliage to the base in late autumn after it has died down, to encourage new growth in the spring. Pruning immediately after flowering will help maintain the plant's appearance and prevent self-seeding if desired.

- Life cycle
Allium insubricum, commonly known as Insubric onion, begins its life cycle as a seed that germinates in well-drained soil, with a preference for sunny locations. Upon sprouting, it develops a root system and a shoot that grows into a slender stem. The leaves are typically narrow and grass-like, emerging early in the growth cycle. The Insubric onion produces a characteristic globular inflorescence composed of small, star-shaped flowers, usually blooming in late spring to early summer. After pollination, often by bees and other insects, the flowers develop into seed capsules containing black seeds that are eventually dispersed, continuing the propagation of the species. The plant is perennial, with bulbs lying dormant underground during the winter, to re-sprout the following spring.
- Propogation
Propogation time
Spring-Early Summer
Propogation: Allium insubricum, commonly known as the Lombardy garlic, is typically propagated through division of its bulbs. The ideal time to propagate is during its dormancy period after the foliage has died back, usually late summer to early fall. To propagate by division, the clumps of bulbs are carefully dug up and individual bulbs are gently separated, ensuring that each bulb retains a portion of the root system. These bulbs can then be replanted immediately at a depth of about two to three inches (5-7.5 cm) and spaced approximately six to eight inches (15-20 cm) apart to allow for sufficient growing space. Water the newly planted bulbs moderately to help establish them. This method utilizes the plant's natural reproductive strategies and typically results in a high success rate for new plant growth.
