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 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.
Oxalis grows best in sun or part shade and are ideal plants for rockeries, containers and borders. They can also be grown indoors in pots in colder regions.
Plant the bulbs in late spring into any well-drained soil, 5 cm deep and 10-15 cm apart. Add a handful of slow-release fertiliser to the soil or compost if you are growing in pots. Provide regular watering to keep the soil evenly moist.
In very cold regions, the bulbs should be lifted and stored in a frost-free place for winter.
