Tall Bearded Iris 'Midnight Oil': A 1997 Keppel Introduction

Tall Bearded Iris 'Midnight Oil' is a striking cultivar introduced in 1997 by hybridizer Keppel. This variety continues the quest for the elusive "black" iris, offering a deep, lustrous color that shines in the garden.

Deep, Lustrous Color

'Midnight Oil' displays large, ruffled flowers of a very dark, glossy purple-black. The color is intense and uniform, with a matching dark beard. The petals have a satiny texture that catches the light, revealing subtle undertones. Stems are tall (36-40 inches), sturdy, and well-branched with a good bud count (7-9).

Garden Performance

This iris is vigorous and reliable. It prefers full sun and well-drained soil to develop its darkest pigmentation. 'Midnight Oil' increases at a moderate rate and forms handsome clumps. It is an excellent choice for creating dramatic contrasts in the perennial border, pairing beautifully with silver foliage, white flowers, or bright chartreuse.
