Impatiens
Impatiens walleriana
The name comes from the Latin "impatient" — ripe seed pods burst at the slightest touch, flinging seeds up to 20 feet (a feature called explosive dehiscence).
How to care for impatiens
Choose downy-mildew-resistant varieties like 'Beacon' or 'Imara XDR' — classic walleriana was decimated by downy mildew starting in 2011. Water deeply and consistently; impatiens collapse dramatically from drought but revive when watered.
