Why Choose Blockbuster Blue Vinca?

This series was bred with gardeners in mind, offering strong genetics and adaptability to challenging summer conditions. The blue-periwinkle blooms add a unique color accent not always found in traditional vinca mixes, creating eye-catching displays when paired with pinks, whites, or apricots.

Key Features of Blockbuster Blue:

Distinctive blue-toned petals with soft, elegant hues.
Compact growth habit, about 10–12 inches tall and wide.
Heat and drought tolerance, perfect for hot summers.
Self-cleaning blooms, keeping plants fresh without deadheading.
Long-lasting color from late spring through fall frost.

How to Grow Vinca Blockbuster Blue from Seed

Growing vinca (periwinkle) from seed requires a little patience but rewards you with plants that thrive in summer conditions.

Sow Indoors: Begin 10–12 weeks before your last frost.
Soil: Choose a sterile, well-drained medium with a pH between 5.5–6.0.
Light & Temperature: Seeds germinate best in darkness at 75–78°F. Cover lightly and maintain steady warmth.
Transplanting: Move seedlings outdoors after frost danger passes and nights stay above 65°F. Space plants 8–10 inches apart.

Care and Maintenance

Once established, vinca requires little care to deliver months of color. Blockbuster Blue thrives with just a few basics:

Sunlight: Full sun for best color and bloom density, though it tolerates partial shade.
Watering: Deep, occasional watering—let the soil dry slightly between watering.
Fertilizer: Apply a slow-release fertilizer at planting, then lightly every 4–6 weeks.
Spacing: Keep 8–10 inches apart to promote airflow and reduce disease risk.

Pairing Blockbuster Blue with Other Varieties

This variety shines when planted alone, but it also mixes beautifully with other vinca cultivars. Try pairing Blockbuster Blue with apricot, white, or red vinca for a bold, colorful palette. For a truly designer look, combine it with patterned blooms like those in the Vinca Tattoo Series.

Perfect for Landscapers and Gardeners

Home gardeners: Add a unique blue-toned flower to containers, walkways, and garden beds.
Professional landscapers: Reliable for high-heat plantings and urban settings.
Bulk planting projects: Large packs are available for wide-scale landscaping needs.
