Oxalis ‘Iron Cross’ is so-called for its quatrefoil leaflets, emblazoned with a dark purple, cross-shaped motif at the centre. Each leaf has a mesmerising nyctinastic habit, opening fully in the sunshine and folding shut at night. In addition to the fascinating foliage, this Oxalis flaunts striking, carmine-pink flowers dangling from long, fine stems. This rewarding plant proves highly versatile, thriving in rock gardens, containers, and borders, as well as making an easy-going, ornamental houseplant. Often referred to as the ‘Good Luck’ plant for its resemblance to a four-leaved clover, you will feel fortunate to add Oxalis ‘Iron Cross’ to your collection.

The dramatic foliage of Oxalis ‘Triangularis Purpurea’ truly sets this plant apart, creating a striking backdrop to the rose-pink, trumpet-shaped blooms. This remarkable species flaunts heart-shaped, trifoliate leaves of burgundy-black, each adorned with imperial purple markings at the centre. The decorative, nyctinastic leaves provide a captivating spectacle as they awaken with the sun and close at night, opening and shutting like butterfly wings. Oxalis are versatile and multi-purpose – equally well-suited to rock gardens, patio pots, hanging baskets, and borders, they also make stunning houseplants. Capitalise on the distinctive, intense colouring by planting alongside lush greenery or contrasting, yellow flowers for an eye-catching summer display.
