Iris ‘Supreme Sultan’

Plant of the month: January

Grass garden

Iris is named for the Greek goddess of the rainbow, referring to the wide variety of flower colours found among the many species. Bearded irises, also known as Pogon irises, have stout surface rhizomes giving rise to fans of sword-shaped, usually broad leaves and simple or branched stems. These rhizomes must not be shaded by other plants but are tolerant of most soils, if well drained, and like full sun. A long, hot summer baking the rhizome will allow the plant to thrive and flower well. ‘Supreme Sultan’ has golden-yellow flowers with deep maroon falls and a light fragrance.
