Titan-ium Mix

Vinca Seeds

The big, bold flowers in all 7 of the Titan-ium series colors are included in this mighty new vinca mix: Apricot, Blush, Dark Red, Polka Dot, Punch, Really Red, and White.

Titan-ium Mix vincas show their strength with strong resistance to the "sudden death" (aerial Phytophthora) that can hit vincas in rainy, humid or extremely hot climates. Rounded, well-branched 14-16 in. plants with glossy, deep green leaves grow 10-12 in. wide, begin blooming in early summer, and continue into fall.  Titan-ium Mix vincas also excel in hot, dry conditions. Count on long-lasting vibrant displays of low-maintenance color in your patio containers, garden beds and borders.

Growing Titan-ium Mix Vinca Seeds

Bee introduces how to plant

Plant Vinca Seeds: Sow Vinca seed indoors 10-12 weeks before your last frost. Starting your seeds later is fine. Use individual cells or flats. Press into soil and lightly cover. Vinca seeds need darkness to germinate. Cover flat with newspaper or place inside black plastic trash bag. Keep out of direct sun. Kept at 75-80°F., germination is in 10-21 days. Remove newspaper cover or trash bag and provide direct light as soon as the first seeds begin to sprout. When plants have 3-4 true leaves transplant into 2-3 in. containers. Place Vinca seedlings into the garden 12 in. apart when soil and air temperatures are consistently above 65°F.

Grow Vinca: Direct sowing Vinca seeds is not recommended. Give plants full sun. In southwest desert climates and the hottest regions of the deep south, afternoon shade is preferred. Vinca plants grow best in well-drained soil with average to low fertility. and tolerate drought, and high heat. In hot, humid climates 'Cora,' and 'Solar' vincas perform best. Flowers drop cleanly, no deadheading needed. Vinca plants are deer and rabbit resistant. Vinca flowers attract butterflies.
