Bloom: Large, showy, azure blue flowers in early spring and a lighter repeat bloom in late summer. Habit: 4-6" tall. Plant 12-24" apart for quick fill in. Exposure: Sun to shade. Site: Plant in average to moist, well drained soil. Spreading rate: Fast. Spreads by above-ground runners. Fertilizing: Feed in early spring and again lightly in early fall. Use a balanced fertilizer, preferably one containing a slow release nitrogen source. Always follow the manufacturer's label recommendations when making any applications of fertilizer. Be sure to rinse the fertilizer off the foliage. Watering: Regular summer water should be provided the first couple of years to ensure good plant establishment and to promote maximum growth. After that, water as needed. Pruning: Prune as necessary. Vinca can be trimmed down to 3-4" tall with a lawn mower if needed during winter. This will give you fresh new growth and a really nice looking planting with terrific bloom if done yearly. Foot traffic: Tolerates light foot traffic. Hardiness: -30° to -20° F. |
