Allium validum aka Swamp Onion

Swamp Onion grows vertically and new growth emerges from the top of the plant.

Swamp Onion’s native range is the Northern Hemisphere, South America, and Africa.

Swamp Onion should be watered regularly, allowing the soil to dry out between waterings.

Swamp Onion loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Swamp Onion thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Pacific Onion.

No additional humidity is required for the Swamp Onion. Plants take in most of their water through their roots, not their leaves, therefore, watering the soil is the most effective way to supply humidity to your plants.

Repotting the Swamp Onion is necessary either when it has doubled in size or once every year, whichever happens first. With fresh potting soil replenished annually, the plant will receive all the necessary nutrients, rendering the use of fertilizer unnecessary. Keep in mind that the source of a plant's energy is the sun, not fertilizer.
