Meet the bold beauty of the bog garden: Dinner Plate™ Tub Tim Grob Japanese Iris. This extraordinary cultivar churns out plate-sized blooms—up to around 6 inches across—each petal a soft lavender-pink canvas veined in richer rose tones and punctuated by a bright yellow central signal. Rising on elegant sword-like foliage, these magnificent blossoms bring elegance and drama in equal measure.

While some perennials shy away from moisture, this Japanese iris flourishes in it. With its roots happily planted in consistently moist soil or near pond edges, it thrives where others falter. The finely textured foliage forms a sleek, upright clump, offering structure and grace even when the blooms have faded—making it both beautiful and practical for wet-garden sites.

Whether you're designing a serene water-garden border, a lush rain-garden oasis, or a cutting bed full of drama, this plant delivers. With deer-resistance built in and performance tailored to wetter spots, Dinner Plate™ Tub Tim Grob Japanese Iris turns challenging landscapes into gallery-worthy displays—delivering both impact and elegance season after season.

DINNER PLATE™ TUB TIM GROB JAPANESE IRIS Homeowner Growing & Maintenance Tips

  • Recommended Soil:
    • Rich, humus-filled loam or clay that retains moisture yet drains well.
    • Soil should stay consistently damp (even boggy) during the growing season.
    • Slightly acidic to neutral pH is best; avoid highly alkaline or bone-dry soils.

  • Sun Exposure:
    • Full sun to partial shade (ideally at least 6 hours of sun).
    • In hot climates, a bit of afternoon shade helps keep blooms fresh and foliage crisp.

  • Irrigation Needs:
    • Requires steady moisture; never allow the soil to dry out during active growth and bloom.
    • Ideal for pond edges, stream banks or depressions where water lingers.
    • After bloom, maintain dampness but avoid prolonged full immersion of rhizomes in freezing climates.

  • Feeding & Nutrients:
    • In early spring, apply a balanced, slow-release fertilizer to support strong shoots and blooms.
    • Mix in compost or well-rotted manure at planting to boost fertility.
    • After flowering, a light feeding helps store energy for next year's show.

  • Pruning & Maintenance:
    • Remove faded flower stalks to tidy the display and direct energy back into the plant.
    • After foliage dies back, trim leaves to ~4–6″ above the soil level in late fall.
    • Every 3–4 years, divide clumps in late summer to maintain vigor and bloom size.
    • In colder zones, apply mulch or ensure a protective cover so rhizomes are not forced to sit submerged in freezing water.

Interesting Notes About DINNER PLATE™ TUB TIM GROB JAPANESE IRIS

  • Plate-Worthy Blooms: The 'Dinner Plate' in the name isn't hype—it's literal size with show-stopper impact.
  • Bog-Garden Specialist: This variety thrives in conditions many plants balk at—wet, heavy soils or pond margins where constant moisture rules.
  • Vein Artistry: Lavender-pink petals finely veined with deeper rose and accented by a vivid yellow signal give each bloom the look of hand-painted porcelain.
  • Water Iris Heritage: As a cultivar of Iris ensata, this plant comes from the Japanese water-iris tradition—historically grown at pond edges and appreciated for its broad, flat blooms.
  • Critter-Friendly Choice: While many prizes in the garden invite deer and rabbits, this cultivar carries the bonus of deer resistance—letting you enjoy the show without extra pest-drama.
