Buying Guide: Key Considerations For White-Flower, Drought-Tolerant Plants

- Watering and establishment: Most plants require regular watering until established. After establishment, choose drought-tolerant varieties to minimize irrigation needs.
- Soil and drainage: Ensure well-draining soil to prevent root rot, especially for succulents and flowering perennials in containers or beds.
- Plant type and space: Ground covers like Purslane need space to spread; shrubs like Viburnum Odoratissimum require room to grow; consider mature size when designing borders.

- Pollinator appeal: Coneflowers and irises support bees and butterflies, enhancing garden biodiversity.
- Maintenance: Some plants require pruning or deadheading to maintain shape and encourage rebloom; others are low-maintenance with minimal input.
