Florist Guide to Impatiens

Impatiens, renowned for their vibrant colours and ability to thrive in shady conditions, are a popular choice for both garden beds and containers. This florist guide covers the essential aspects of caring for and arranging these delightful blooms.

Botanical Overview

• Scientific Name: Impatiens walleriana

• Common Names: Busy Lizzie, Touch-Me-Not

• Family: Balsaminaceae

Varieties

Several varieties of Impatiens are available, most notably:

• Impatiens walleriana: The traditional variety with a wide range of colours.

• New Guinea Impatiens: Larger flowers and sturdier foliage, suitable for sunnier spots.

• SunPatiens: A hybrid variety that thrives in full sun and offers more colour resilience.

Light Requirements

Impatiens prefer partial to full shade. They can tolerate early morning sun but should be protected from the harsh midday rays. Lack of adequate light can lead to leggy growth and reduced blooming.

Soil Preferences

Well-draining, rich, and loamy soil is ideal for Impatiens. A soil pH between 6.0 and 7.0 promotes healthy growth. Adding compost or well-rotted manure can enhance soil fertility and structure.

Watering Guidelines

Impatiens require consistent moisture but are sensitive to waterlogging. Water regularly, ensuring the soil remains evenly moist but not soggy. Allow the top inch of soil to dry out between waterings to prevent root rot.

Fertilisation

Feed Impatiens with a balanced, water-soluble fertiliser every 4-6 weeks during the growing season. A high-phosphorus fertiliser can encourage blooming but must be balanced with nitrogen for healthy foliage.

Pest and Disease Management

• Common Pests: Aphids, whiteflies, and spider mites may infest Impatiens. Regular inspections and natural insecticidal soap can help control these pests.

• Diseases: Powdery mildew and downy mildew can affect Impatiens, especially in humid conditions. Ensure good air circulation and avoid overhead watering to mitigate these issues.

Arranging Impatiens

Impatiens can be used effectively in floristry as cut flowers or for decorative accents in arrangements. Consider the following when arranging:

• Colour Palette: Combine various colours for a vibrant effect or select monochromatic hues for a more elegant look.

• Foliage: Include lush greenery to complement the blooms and provide contrast.

• Containers: Choose containers that allow for good drainage; ceramic or terracotta pots work well.
