Soiree® Vinca (Catharanthus roseus) is a premium, heat-loving annual prized for its masses of small, colorful blooms and glossy green foliage. Unlike traditional vinca, the Soiree series features a compact, mounding habit covered with hundreds of flowers from spring until frost. It thrives in hot, humid conditions and continues blooming when many other annuals slow down. Excellent for garden beds, borders, containers, and hanging baskets, Soiree Vinca attracts butterflies and requires minimal maintenance once established. Its drought tolerance and nonstop color make it a standout performer for summer landscapes.
