Nubia™ (‘Evipo079’) Clematis is a beautiful introduction from Raymond Evision. The large flowers are a deep crimson red, on a somewhat compact vine. Clematis Nubia™ is part of the Boulevard® series, and performs well on trellises and fences. A very cool use for Clematis is in combination with shrubs, where the plants can support the vine and display the flowers. Nubia™ should be pruned in late winter or early spring.
