Impatiens, also known as “Busy Lizzies” or “Touch-me-nots”, are popular annual flowers appreciated for their vibrant colors and shade tolerance. With over 1,000 species, this genus, scientifically named Impatiens (Latin for “impatient”) due to their seed capsules that burst open when touched, is a favorite for adding cheer to shady gardens.

Ideal Growing Conditions:

• Shade and Sunlight: Impatiens thrive in partial to full shade. They prefer locations that receive 2-4 hours of morning sun or filtered sunlight throughout the day, and afternoon shade. While they can tolerate heavy shade, they may produce fewer blooms. Avoid planting in full sun, which can scorch their leaves.
• Soil: They prefer moist, well-drained soil that is rich in humus. A slightly acidic pH between 6.0 and 6.5 is ideal, but they are not overly particular about soil pH. For container planting, use high-quality potting soil or a peat moss-based mix. If planting in the ground, amend heavy clay soil to improve drainage.
• Watering: Impatiens need regular watering to keep the soil consistently moist but not waterlogged. Avoid letting the soil dry out completely. In pots, ensure there is drainage to prevent root rot from standing water.
• Temperature: Being tropical plants, Impatiens are sensitive to cold. Plant them outdoors only after the last spring frost when nighttime temperatures consistently stay above 50°F (10°C).

Planting Impatiens:

• Starting from Seeds: For those starting from seeds, sow them indoors 8-10 weeks before the anticipated outdoor planting date. Use small pots or cell packs filled with moistened seed-starter mix or potting soil, placing seeds about 1/2 inch deep. Cover with plastic or glass to maintain moisture like a mini-greenhouse.
• Spacing: When planting seedlings or purchased plants, space them 10-12 inches apart in the garden to allow for adequate air circulation and growth.
• Planting Time: The best time to plant Impatiens is after the last spring frost.

Choosing Pots:

• Suitable Pot Types: Impatiens are well-suited for various containers, including plastic, metal, and non-porous materials that retain moisture. Pots that are 8 to 12 inches deep are generally a good starting size, depending on the variety. They also thrive in hanging baskets, window boxes, and deck railing planters, especially varieties with a larger spread.
• Drainage: Ensure that any pot you choose has drainage holes to prevent water from pooling at the bottom, which can lead to root rot.
• Potting Mix: Use a lightweight growing medium suitable for annuals or a peat moss-based potting mix to ensure good drainage and nutrient availability.

Care Tips:

• Fertilizing: Impatiens benefit from regular feeding. For potted plants, use a water-soluble fertilizer every 2-3 weeks during the growing season.
• Deadheading: While not strictly necessary, removing spent flowers (deadheading) can encourage more blooms and keep the plants looking tidy.
• Location: Place potted Impatiens in a location that receives partial shade, such as under shady trees or near shrubs that offer protection from direct sunlight.

In summary, Impatiens are a delightful addition to any shady garden spot or container. With their easy-going nature and continuous blooms, they bring color and life throughout the growing season. Remember to provide them with shade, consistent moisture, and well-draining soil, and you’ll be rewarded with a profusion of flowers.
