Seasonality
|
– Spring: Emerges late—often not until May
– Summer: Peak flowering from July through September
– Fall: Foliage may turn shades of orange-red before dormancy
– Winter: Dormant—top growth dies back; root system overwinters |
Ideal For
|
– Late-season drama
– Pollinator-friendly gardens
– Accent in borders
– Rain gardens |
Leaf Description
|
– Color: Deep wine-purple to nearly black
– Shape: Maple-like, deeply lobed leaves
– Texture: Smooth, thick, and leathery
– Seasonal Color: Retains deep purple through summer, turning red-orange in fall |
Flower Description
|
– Color: Deep scarlet red with darker eye
– Size: 8–9 inches across
– Shape: Broadly rounded petals, slightly overlapping, with prominent central stamens
– Bloom Period: Mid-summer to early fall
– Duration: Each bloom lasts one day, but plant blooms in succession for several weeks |
Planting Instructions
|
– Best Time to Plant: Spring or early fall
– Soil Preparation: Enrich with compost or organic matter; ensure good drainage but consistent moisture retention
– Planting Depth: Same depth as in the nursery container; firm soil gently around roots
– Spacing: Space 36–48 inches apart to allow for mature width and airflow
– Mulch: Apply 2–3 inches of mulch to conserve moisture and insulate roots |
Pruning & Maintenance
|
– Deadheading: Optional—each bloom lasts 1 day, but blooms continuously without deadheading
– Fall/Winter Pruning: Cut back to 4–6 inches above ground after first frost or in early spring before new shoots emerge
– Stem Removal: Remove weak or crossing stems to encourage airflow and structure |
Water Needs
|
– Moisture Needs: Consistently moist soil preferred; avoid drought
– Establishment: Water 2–3 times per week during first growing season
– Mature Plants: Water weekly, more in heat or dry spells
– Soil Preference: Tolerates average to clay soils as long as moisture is retained |
Light Needs
|
– Ideal Exposure: Full sun (minimum 6 hours of direct sun daily)
– Effect of Light: Full sun enhances flower production and deepens leaf coloration
– Tolerates: Light shade, but may reduce blooming and lead to leggier growth |
Harvesting
|
– Cut Flowers: Flowers are large and beautiful, but short-lived in arrangements (1 day)
– Best Use: Use cut stems for dramatic but brief displays
– Seed Harvest: Possible if not deadheaded; collect after capsules dry on plant |
Fertilizing
|
– Timing: Apply in early spring as new growth emerges and again in midsummer
– Type: Balanced, slow-release fertilizer (e.g., 10-10-10)
– Frequency: Twice per season; over-fertilizing can lead to foliage overgrowth at the expense of blooms |
Pollination
|
– Pollinated by: Bees, butterflies, and hummingbirds
– Pollination Type: Self-fertile but enhanced by cross-pollination from insects
– Seed Set: Possible but not typically used for propagation due to hybrid origin
– Ornamental Value: Primarily grown for flowers and foliage, not seed production |
Companion Plants
|
– Salvia nemorosa – offers vertical blue spikes to contrast the red blooms
– Pennisetum (Ornamental Grasses) – adds texture and movement
– Echinacea (Coneflowers) – long-blooming, attracts pollinators alongside hibiscus
– Rudbeckia – sunny yellow blooms pair beautifully with red flowers
– Sedum ‘Autumn Joy’ – late-season color match
– Coreopsis – for low-maintenance, sunny companions
– Russian Sage (Perovskia) – adds airy texture around the bold hibiscus form |
