Purple Oxalis leaves are edible and have a tangy, lemony flavor due to their oxalic acid content. They can be used to add a zesty taste to salads, sandwiches, and garnishes. The leaves are also excellent when mixed into sauces, soups, and stews, providing a fresh, citrus-like accent to dishes. While they can be eaten raw, it’s recommended to consume them in moderation due to the oxalic acid, which can interfere with mineral absorption in large quantities.
Our Purple Oxalis plants are shipped in 4" biodegradable coconut coir planters that can be planted directly in the soil, promoting strong root growth and ensuring an eco-friendly start.
