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.
