Impatiens walleriana, mixed‑color African impatiens, produces masses of bright flat‑faced blossoms across red, pure white and vivid pink‑magenta shades. Dense glossy green foliage forms bushy mounded clumps that stay neat throughout the growing season.
These flower seeds create reliable‑flowering annuals that shine in partial shade, where many sun‑demanding flowers struggle to perform. They work beautifully mass‑planted in shaded garden beds, arranged in patio pots and hanging baskets, or used to fill gaps along dim borders. Consistent moisture is important, yet soggy ground easily triggers stem rot. Avoid intense full mid‑day sun which can scorch leaves. With suitable temperature and moisture, plants keep blooming steadily over a long summer period. Planting Instructions Soil Preparation Pick spots with partial shade or dappled filtered sunlight. Humus‑rich, loose, well‑drained loam soil brings best results. Mix compost into low‑fertility planting ground. Prevent water‑logged low‑lying positions. Slightly acidic soil is preferred.
Seed Pre‑treatment No cold stratification required.
Sowing Method Start indoors 8‑10 weeks before last frost date. Press tiny seeds onto moist soil surface, do not cover with soil, impatiens seeds need light for germination. Keep 20‑25 cm spacing between mature plants. Direct outdoor sowing is difficult due to small seed size; indoor seed starting is recommended.
Germination Condition Optimal germination temperature:20‑24°C. Seedlings emerge within 10‑21 days. Maintain high humidity during sprouting, avoid direct strong sunlight.
Daily Maintenance Partial shade or filtered light is ideal; protect from harsh mid‑day heat. Keep soil evenly moist, never let substrate become waterlogged. Apply diluted gentle fertilizer during active growth. Remove faded blooms casually. Watch for downy mildew under overly cool damp conditions.

FAQ Q1: Do impatiens walleriana seeds need covering soil? A1: No, seeds require light to germinate, only press onto moist growing medium surface. Q2: Can African impatiens grow under full sun? A2: It tolerates soft morning sun, intense mid‑day sunlight will burn leaves and weaken growth. Q3: Why do stems turn soft and collapse? A3: Over‑watering and poor drainage cause stem rot; keep soil moist but never saturated. Q4: Is direct outdoor sowing recommended? A4: Not ideal, seeds are extremely tiny; indoor starting gives much higher success rate. Q5: What disease should be watched for? A5: Downy mildew may break out in cool humid weather; improve air circulation among plants.
