SOWING INSTRUCTIONS
Depth:
Just cover; scarify by chipping or filing seed and then soak in warm water for about an hour prior to sowing.
Seed To Bloom:
14-16 weeks
Starting Indoors:
Start in pots 8 weeks before the last spring frost. Keep at about 70-80°F. Sterile germinating mix is the preferred growing medium to prevent fungal problems.

Direct sow after last spring frost in warmer areas (zones 7+).
WHEN TO SET OUTSIDE
2 weeks after last springtime frost.
PLACEMENT & CULTIVATION
Hibiscus 'Mahogany Splendor' adds depth and complexity to mixed borders, its deep burgundy red foliage the perfect backdrop to bright red flowers such as lobelia and hibiscus 'Texas Star'. Also outstanding as a hedge and container specimen. Full sun brings out the deep, rich coloring. It thrives in summer's heat and humidity—plant in a warm, sheltered spot in moist, well-drained soils. Teardrop-shaped buds open to burgundy flowers in longer season areas in late summer and fall. Self-sows where hardy.
Soil pH:
Prefers neutral but will tolerate slightly acidic to slightly alkaline
Fertilizer:
Mix in about 2" of compost prior to planting, and mix in about an inch each spring if growing as a perennial.
Diseases & Pests:
If aphids are a problem, hose down the plants daily until the insects are no longer present; neem oil is also effective at controlling an infestation.
