Also referred to as wild iris or fortnight lily, this fast-growing clumping plant has large, white iris-like flowers with a mauve centre and distinctive yellow spots on each petal.
	
	
Will happily grow in both gardens and pots but looks most striking when planted en masse.
	
	
	
Almost indestructible, this is a top plant-and-forget pick.
	
	
	
 Available in a 140mm pot.
