Stands up to heat, humidity, and rain beautifully, and blooms heavily all summer. No More "Sudden Death" VincasUntil now, Vinca has been prey to "sudden death" in humid, rainy, or very hot climates. Now the cure has been discovered, and Cora™ is ready to thrive in most damp and moist conditions without turning a petal. Cora™ was the only Vinca to survive until frost in punishing garden trials in Dallas.Winner of the Dallas Arboretum's "Flameproof" award for outstanding performance in extreme heat. This is a plant that can take climate stress of all types in stride. It's a whole new day for this lovely, long-blooming plant!A new series called Cora is about to put the joy back into growing Vinca or periwinkles. If you have ever planted periwinkles that quickly shriveled and died, the likely culprit was a disease called aerial phytophthora. There are other disease possibilities, but this is the most likely cause of growers' unhappiness with what was one of our most beloved annuals. The variety did as expected in university gardens, showing off its durability and beauty. In addition to the disease resistance, I am happy to report that the flowers themselves are quite large and very showy. Flowering heavily all summer (and sometimes in late spring and early fall as well), this plant is eye-catching and very, very easy to grow.The leaves are dark green and glossy, contrasting with the gorgeous flowers. Even though the Cora is disease resistant, there is no use planting too early. Wait until the soil has warmed and the plant is able to expand out of its rootball with vigor. Pay close attention to planting depth. Planting individual plants too deeply exposes the roots and stems to unfavorable growing conditions. Add a good layer of mulch after planting to stabilize soil temperatures and prevent rapid loss of moisture through evaporation. Mulch also will deter weeds from growing and competing for nutrients and water. Once established, the Cora vinca will tolerate droughts, so don't overwater. And now there is a trailing version - Cora® Cascade™ - that gives the same great heat-loving, disease-resistant performance in a form that is perfect for hanging baskets. With both Cora® and Cora® Cascade™, landscapers and gardeners can now look forward to a vinca that will thrive with strength and beauty all season long.Cora vinca plants reach 14 to 16 inches in height, with a spread of around 2 feet.
