This guide introduces some of the best annuals suited for low-water gardening in Zone 6, along with planting tips to ensure their success.

Understanding Zone 6 and Water Needs

Zone 6, according to the USDA Plant Hardiness Zone Map, experiences average minimum winter temperatures between -10°F and 0°F. This zone supports a wide variety of plants, but water conservation remains important, especially during dry summer months. Choosing drought-tolerant annuals can reduce your watering needs and promote a sustainable garden.

  • Marigolds: Hardy and vibrant, marigolds tolerate dry conditions once established.
  • Sweet Alyssum: Produces fragrant white flowers and prefers well-drained soil with minimal watering.

Planting Tips for Success

To maximize the success of low-water annuals in Zone 6, follow these planting tips:
