Flowers for Specific Conditions
Full Sun (6+ hours of direct sunlight daily)
- Sunflowers: Thrive in full sun; sow seeds directly in the soil after frost. They’re drought-tolerant once established.
- Zinnias: Perfect for sunny spots; they require regular watering at the base to prevent fungal issues.
- Lavender: Loves sunny and dry conditions; avoid overwatering as it prefers well-drained, slightly alkaline soil.
- Roses: Ensure they get at least 6 hours of sun daily. Water deeply but infrequently to encourage deep root growth.
Partial Shade (3-6 hours of sunlight daily)
- Begonias: Excellent for shaded spots; keep soil consistently moist but not soggy.
- Hydrangeas: Do well in morning sun and afternoon shade; mulch to retain soil moisture.
- Impatiens: A classic choice for shaded areas; water regularly to keep soil moist.
- Fuchsias: Great for hanging baskets in shaded spots; avoid letting the soil dry out completely.
Drought-Tolerant Flowers
- Lavender: Ideal for hot, dry climates. Space plants to allow for good airflow.
- Sedums (Stonecrop): Low-maintenance and thrive in poor, dry soil.
- Yarrow: Offers long-lasting blooms; prefers poor to moderately fertile soil.
- California Poppy: Self-sowing annual that tolerates drought and blooms profusely.
Cool-Weather Flowers
- Pansies: Plant in early spring or fall; they thrive in cooler weather and add cheerful color.
- Snapdragons: Best planted early in the season; tolerate light frost and provide vibrant blooms.
- Primroses: Perfect for cool, shady gardens; water them consistently.
- Sweet Alyssum: Hardy and fragrant; thrives in cool conditions and self-seeds readily.
Wet Soil Tolerance
- Iris (Siberian or Louisiana): Ideal for damp or boggy soil; plant rhizomes just below the surface.
- Canna Lilies: Tolerate wet feet and provide a tropical look; great for pond edges.
- Astilbe: Perfect for wet, shady areas; provide consistent moisture.
- Marsh Marigolds: Naturally thrive in wet or marshy soil conditions.
Tips for Popular Flowers
Roses
- Soil: Slightly acidic (pH 6-6.5), rich, and well-drained.
- Fertilizing: Apply a balanced fertilizer during the growing season. Avoid over-fertilizing to prevent weak growth.
- Pruning: In early spring, prune deadwood and shape the plant for better airflow.
Tulips
- Bulb Care: Plant in fall before the first frost; ensure good drainage to prevent rot.
- Post-Bloom: Let foliage die back naturally to nourish the bulb for next year’s growth.
Peonies
- Spacing: Space plants well to prevent fungal diseases.
- Support: Use stakes or hoops for large blooms to prevent flopping.
- Dividing: Divide mature plants every 8-10 years in the fall.
Marigolds
- Pest Control: Companion plant near vegetables to deter pests.
- Maintenance: Deadhead regularly for continuous blooms.
