Bearded irises have 'beards' on each of the falls (lower petals) of the flowers. Iris 'Rajah' has gorgeous and very distinctive bicoloured flowers, with butter-cup-yellow standard petals and maroon yellow-flecked falls with orange-yellow beards. Flowers have a spicy and fruit fragrance.
Grow it in a mixed herbaceous border or gravel garden, ideally dotted through herbaceous plants in groups of three or five.
For best results grow Iris 'Rajah' in well-drained soil in full sun, and mulch with well-rotted manure or garden compost annually.
