Buying Guide
What to consider when selecting purple leaf fountain grass:
- Climate and hardiness: Check zone recommendations. Some varieties are best treated as annuals in cooler regions, while others are true perennials in warmer climates.
- Sun and soil: Most purple fountain grasses prefer full sun and well-drained soil. Good drainage helps prevent root rot in wetter areas.
- Size and mature height: Compare height and spread to ensure the plant fits borders, containers, or designated focal areas.
- Maintenance needs: Drought-tolerant options reduce watering but may require occasional pruning or deadheading to maintain form.
- Color and texture: Select forms with strong maroon or smoky purple tones to maximize contrast in mixed plantings.
- Container suitability: If planting in pots, choose compact varieties with slow to moderate growth to avoid frequent repotting.
