Impatiens: Growing Colorful Shade-Loving Annuals for Gardens and Containers

White and orange impatiens

Impatiens are delightful annuals that shine as houseplants or summer bedding plants. Known as "Busy Lizzie," their name derives from the Latin for their explosive seed pods—the slightest touch sends ripe seeds flying. Impatiens thrive in shade and moisture.

Planting Impatiens

• Plant transplants after the last spring frost in humus-rich, moist, well-drained soil. Provide wind shelter.
• Closer spacing yields taller plants (6–30 inches). For low, mounding bedding plants, space 8–12 inches apart.
• Amend soil with compost or slow-release fertilizer before planting.
• For containers, use sterile soilless mix for optimal drainage.

Essential Care

• Water consistently: This is the #1 rule. Keep soil moist but not soggy. Dry plants drop leaves; overwatering invites fungal diseases.
• Container plants need more frequent watering.
