Combining and Arranging Fragrant Flowers for Maximum Impact

The secret to a showstopping and aromatically rich window box is layering scent and color. Consider the following arrangement tips:

• Mix Heights & Habits: Place taller, upright flowers (like miniature roses or lavender) at the back, with mounding plants (dianthus or phlox) in the middle, and trailing or spilling options (alyssum, nemesia) at the front or sides.
• Blend Seasonal Scents: Combine early, mid, and late-season bloomers for months of ongoing fragrance.
• Color Coordination: Contrasting colors pop, while analogous tones provide a calm, harmonious look.
• Don't Overcrowd: Fragrant flowers often need good air circulation for optimal scent.
• Save a Spot for Greenery: Foliage plants like scented pelargoniums add visual and olfactory interest.

Planting and Care Tips for Fragrant Window Boxes

• Use a High-Quality Potting Mix: Good drainage is vital, especially for lavender and heliotrope.
• Regular Deadheading: Remove spent flowers to prolong blooming and scent production.
• Feed Sparingly: Over-fertilization can induce leafy growth at the expense of flowers and scent.
• Water Properly: Consistent but not soggy moisture keeps roots healthy--avoid watering the foliage directly.
• Rotate for Sun: If possible, rotate your window box occasionally, so all sides receive enough light.
• Protect from Wind: Fragrant flowers are usually light and delicate, so ensure your window boxes are sturdy and sheltered from strong gusts.
