Tall Bearded Iris 'Sea Power': A 1998 Keppel Introduction

Tall Bearded Iris 'Sea Power'

Hybridized by Keppel and registered in 1998, Iris 'Sea Power' emerges from one of America's most prolific and celebrated iris breeding programs. The Keppel family (particularly Keith Keppel) has introduced hundreds of acclaimed cultivars, consistently pushing the boundaries of color, form, and garden worthiness.

Botanical Classification

• Family: Iridaceae (eye-rid-AY-see-ee)
• Genus: Iris (EYE-ris)
• Cultivar: 'Sea Power'
• Type: Tall Bearded Iris (TB)

The Keppel Breeding Program

Keith Keppel's Oregon-based program is legendary in iris circles. His cultivars are known for exceptional branching, high bud counts, novel color breaks (including the "broken color" and "luminata" patterns), and remarkable vigor. A 1998 introduction like 'Sea Power' benefits from decades of meticulous selection and represents the cutting edge of late-1990s TB breeding.

Anticipated Features

The evocative name 'Sea Power' suggests a cultivar with commanding presence—perhaps deep blue or violet tones reminiscent of ocean depths, or possibly a dynamic color combination that shifts like tidal waters. Modern Keppel introductions typically exhibit the full suite of contemporary TB traits: broad, heavily ruffled falls; strong, multi-branched stalks with 9+ buds; clean, disease-resistant foliage; and reliable increase.

Garden Culture

Follow standard tall bearded iris culture: full sun, well-drained soil, shallow planting. Keppel cultivars are noted for adaptability across climate zones. In hot summer regions, some afternoon shade may benefit bloom longevity. Fertilize sparingly with low-nitrogen formula. Divide clumps every 3–4 years to maintain the vigorous growth that characterizes Keppel lines.
