Common names

- Toxicity
To humans
The common name for Oxalis enneaphylla 'Sheffield Swan' is Scurvy Grass. Like many species in the Oxalis genus, Scurvy Grass contains oxalic acid, which is toxic to humans if ingested in large quantities. It can be harmful due to its ability to bind with calcium in the body, potentially leading to calcium oxalate stones, commonly known as kidney stones. Symptoms of oxalic acid poisoning can include a burning sensation in the mouth and throat, difficulty swallowing, nausea, vomiting, diarrhea, and abdominal pain. In severe cases, kidney damage or failure may occur. While occasional small amounts as part of a diet may not be harmful, consuming larger quantities of the plant or its extracts can lead to these adverse effects.
To pets
Scurvy Grass contains oxalic acid, which is also toxic to pets such as dogs and cats, if ingested in significant amounts. The symptoms of oxalic acid poisoning in pets are similar to those in humans and can include vomiting, diarrhea, drooling, lethargy, weakness, tremors, and abdominal pain. Ingestion of large amounts of oxalic acid can lead to kidney failure in severe cases. Pets that consume Scurvy Grass should be taken to a veterinarian for appropriate care and treatment. As with humans, consuming small amounts may not cause immediate harm, but it is generally advised to prevent pets from ingesting this plant to avoid the risk of toxicity.

- Water
The Argentine sarsaparilla requires watering when the top inch of soil feels dry to the touch, typically once a week, though this may vary with climate and indoor conditions. Gradually pour water evenly around the base of the plant until it runs out of the drainage holes, which may be approximately 16-24 onzes for small to medium-sized pots or up to 1-2 gallons for larger pots, depending on pot size and plant's growth stage. During its dormancy in winter, reduce watering frequency to bi-weekly or even less, just to keep the soil slightly moist. Avoid letting the plant sit in water as this can lead to root rot.
- Light
The Argentine sarsaparilla thrives in bright, indirect light. A spot near an east or west-facing window where the plant can receive gentle morning or evening sunlight is ideal. Protect the plant from intense direct afternoon sun, which can scorch the delicate foliage.
- Temperature
The Argentine sarsaparilla prefers a cool to moderate temperature range, ideally between 50 to 75 degrees Fahrenheit. It can withstand minimum temperatures down to around 40 degrees Fahrenheit and should be protected from extremes above 80 degrees Fahrenheit, which could cause stress or damage.
- Pruning
Pruning the Argentine sarsaparilla is usually done to remove spent flowers or damaged foliage, enhancing the plant’s appearance and encouraging healthy growth. Light pruning can be carried out throughout the growing season as needed. The best time for more extensive pruning is in late winter or early spring before new growth begins.
- Cleaning
As needed
- Soil
The Scurvy-grass Sorrel thrives best in a soil mix with good drainage, consisting of a blend of loam, peat, and sand. Aim for a slightly acidic to neutral pH between 5.5 to 7 for optimal growth.
- Repotting
The Scurvy-grass Sorrel should typically be repotted every two to three years to refresh the soil and accommodate root growth. Overly frequent repotting can stress the plant.
- Humidity & Misting
The Scurvy-grass Sorrel prefers moderate to high humidity levels but is tolerant to a range of conditions; strive for 40-50% if possible for optimal growth.
- Suitable locations
Indoor
Keep in bright, indirect light with well-draining soil.
Outdoor
Plant in partial shade with well-drained soil and shelter.
Hardiness zone
7-9 USDA
- Life cycle
Oxalis enneaphylla 'Sheffield Swan', commonly known as Patagonian oxalis or Scurvy grass, begins its life cycle with seed germination in favorable conditions, typically in moist and well-drained soil with exposure to bright but indirect light. After sprouting, the seedling develops into a young plant with characteristic clover-like leaves, entering a vegetative growth phase where it focuses on establishing a strong root system and foliage development. During the flowering stage, which occurs in spring to early summer, 'Sheffield Swan' produces pale pink to white flowers with a distinct cup shape, attracting pollinators that aid in its reproductive process. Post pollination, the flowers develop into seed capsules that, when mature, rupture to disperse seeds for the propagation of new plants. In preparation for winter, the plant enters a dormancy stage where above-ground foliage dies back, and the bulbous underground structures store energy to survive the cold season. At the arrival of spring, Oxalis enneaphylla 'Sheffield Swan' re-emerges from dormancy, completing the cycle, and begins to grow and flower once more.
- Propogation
Propogation time
Spring-Early Summer
Oxalis enneaphylla 'Sheffield Swan', commonly known as the scented wood sorrel, is best propagated through division, which is the splitting of its bulb-like structures called corms. This is typically done in the fall after the leaves have died back or in early spring before growth begins. To propagate by division, carefully unearth the corms and gently pull apart the clusters, ensuring that each new section has at least one growth point. Replant the divided corms immediately at a depth of about 1 inch (2.54 centimeters), spacing them about 4 inches (approximately 10 centimeters) apart in well-draining soil with good exposure to sunlight. This simple method efficiently multiplies your scented wood sorrel plants while maintaining the health and characteristics of the parent plant.
