Why Choose This Style for Rhode Island?

Moderate maritime climate with less extreme temperatures

🌱

Long growing season influenced by ocean warmth

💚

Adequate rainfall reducing irrigation needs

Climate Adaptation for Rhode Island

Rhode Island's cottage gardens peak in late spring (May-June) with roses, peonies, and irises, followed by summer displays of daylilies, phlox, and hydrangeas. Coastal gardens benefit from moderated temperatures while inland areas experience greater extremes. Plant in spring or early fall for best establishment. Protect coastal gardens from salt spray and wind. The maritime climate allows for extended growing seasons and diverse plant selection.

Key Challenges
  • Salt spray and wind in coastal areas requiring salt-tolerant plants
  • Sandy or rocky soils in many areas needing amendment for fertility
  • Occasional nor'easters bringing wind and salt damage
  • High humidity in summer promoting fungal diseases
  • Variable winter temperatures with potential freeze-thaw cycles
Regional Advantages
  • Moderate maritime climate with less extreme temperatures
  • Long growing season influenced by ocean warmth
  • Adequate rainfall reducing irrigation needs
  • Ocean breeze providing cooling in summer
  • Excellent conditions for many cottage garden favorites

Key Design Principles

Abundant Mixed Plantings

Layer plants densely with tall hollyhocks and delphiniums at the back, mid-height roses and hydrangeas in the center, and low-growing catmint and thrift at the front. Allow plants to intermingle naturally while considering wind exposure in coastal locations.

Romantic Color Palette

Embrace soft pastels (pinks, lavenders, blues) that complement the coastal light, mixed with vibrant jewel tones and white blooms. Create drifts of repeating colors throughout the garden. Include silvery foliage plants that tolerate salt spray.

Vertical Interest with Climbers

Train climbing roses, clematis, and honeysuckle on arbors, trellises, and weathered fences. Use vertical elements to maximize bloom space and create charming focal points. Choose sturdy structures that withstand coastal winds.

Curved Informal Pathways

Design winding paths of brick, gravel, or bluestone that invite exploration. Edge with sprawling plants that soften hard lines. Create discovery moments with benches, driftwood accents, or coastal-inspired garden art.

Succession of Blooms

Select plants for continuous flowering from early spring bulbs through fall asters. Combine spring ephemerals, summer perennials, and fall bloomers. Deadhead regularly to extend bloom periods in the long maritime growing season.

Traditional Cottage Elements

Incorporate white picket fences, weathered arbors, vintage containers, and bird-friendly features. Use reclaimed materials and nautical accents. Blend cottage charm with coastal New England character.
