The glossy, dark green foliage forms a lush backdrop for the cheerful blooms, maintaining a tidy, attractive appearance throughout the season.
XDR: Extra Disease Resistance
The “XDR” in its name stands for Extra Disease Resistance. This series is specifically bred to resist aerial phytophthora, a fungal disease that often plagues vinca in humid climates. This trait ensures healthier plants, fewer maintenance concerns, and reliable performance in challenging summer conditions.
Best Growing Conditions
Sunlight
Thrives in full sun — at least 6–8 hours daily. Full sun promotes dense growth and abundant blooms, though light afternoon shade is tolerated in extremely hot regions.
Soil
Prefers well-drained soil. Sandy or average garden soils work well; avoid heavy, soggy soils that may cause root problems.
Heat and Drought Tolerance
This variety excels in hot, dry conditions where many annuals struggle, continuing to bloom through midsummer heat waves.
Planting Guide
- Timing: Plant in late spring after all danger of frost has passed.
- Spacing: Allow 12–18 inches between plants for proper airflow and room to trail.
- Soil Preparation: Loosen soil and amend with compost for improved drainage and fertility.
- Watering at Planting: Water thoroughly to settle roots, then reduce frequency as plants establish.
Watering and Fertilizing
- Watering: Moderate needs — water deeply during establishment, then let soil dry slightly between waterings. Avoid constant moisture.
- Fertilizing: Apply a balanced, water-soluble fertilizer every 4–6 weeks during the growing season to maintain healthy growth and blooms.
Maintenance and Care
- Deadheading: Not required; flowers are self-cleaning.
- Pruning: Trim trailing stems lightly if they become too long or to encourage fuller branching.
- Pests and Diseases: Naturally resistant to major diseases; occasional aphids or whiteflies can be managed with insecticidal soap or a strong stream of water.
Seasonal Performance
- Spring: Establishes quickly in warming soil and begins flowering early.
- Summer: Peak bloom period; thrives even in extreme heat and sun.
- Fall: Continues flowering until frost, offering late-season color when other annuals fade.

The trailing form and polka-dot blooms make this variety perfect for:
- Hanging baskets and window boxes: Creates cascading displays of white and pink.
