Impatiens walleriana, commonly known as Busy Lizzie, is a tender, shade-loving perennial usually grown as a warm-season annual for nonstop blooms. Native to the moist understories of eastern Africa, it forms compact, mounding plants 20–45 cm tall with succulent stems and glossy, serrated, oval leaves. Flowers appear freely from late spring until frost in a wide palette—white, pink, coral, red, lavender, and bi-colors—in single or double forms. The genus name refers to its explosive seed capsules that disperse seeds when touched. Garden impatiens thrive in evenly moist, well-drained, humus-rich media and are particularly valued for brightening deep shade and containers. While historically ubiquitous in bedding schemes, the species has faced downy mildew outbreaks; newer resistant series help restore dependable performance. With proper moisture, filtered light, and good airflow, plants remain lush and floriferous for months. Indoors, they make cheerful seasonal houseplants when given bright, indirect light and consistent hydration.

How to care for Busy Lizzie
Water
Keep the root zone consistently moist but never waterlogged. Water thoroughly until excess drains, then allow the top 2–3 cm of mix to dry before watering again. Increase frequency in heat and containers, and decrease in cool, low-light periods. Always use pots with drainage and empty saucers promptly. Water at the base, preferably in the morning, to keep foliage dry and reduce disease pressure. Brief midday wilting can occur in hot weather; if soil is moist, plants usually recover by evening.
Light
Provide bright, indirect light to part shade. Outdoors, 2–4 hours of gentle morning sun with afternoon shade is ideal; avoid harsh midday/afternoon sun that scorches leaves. In deep shade, plants remain healthy but flower less. Indoors, place near an east- or bright north-facing window, or diffuse south/west light with sheer curtains. Rotate pots periodically for even growth. Excessive sun causes leaf scorch and wilting; too little light leads to stretching and sparse blooms.
Nutrients
Mix compost or a slow‑release balanced fertilizer into the potting medium at planting. During active growth, feed every 2–3 weeks with a balanced liquid fertilizer at 1/4–1/2 strength (e.g., 10‑10‑10 or 15‑5‑15). Reduce feeding during extreme heat or low light to avoid soft, leggy growth, and pause in winter or when growth slows. Flush the potting mix monthly with clear water to prevent salt buildup. Include micronutrients (especially iron and magnesium) if leaves pale despite adequate nitrogen.
Temperature
Ideal temperatures are 18–24°C (65–75°F). Growth slows below 10°C (50°F), and frost is fatal. In very hot weather (>30°C/86°F), provide deep shade, consistent moisture, and mulch to prevent stress and flower drop. Best outdoors year-round in frost-free climates (USDA 10–11); elsewhere grow as a summer annual or indoor seasonal. Avoid cold drafts and sudden temperature swings. Night temperatures of 16–20°C (60–68°F) help sustain steady flowering.
