(Clematis) For years, Silmakivi™ is one of Garden Crossings favorite! Silmakivi™ Clematis stands only 6-8 feet tall, but puts on a huge show. This clematis is perfect for a container or small garden trellis. A free flowering cultivar, Silmakivi™ has an abundance of 6 inch flowers that are pale lavender blue with lighter blue stripe. Silmakivi™ is a long blooming variety, beginning in June and continuing through September! Hardy in zones 4-9, Silmakivi™ prefers to be planted in full sun. My favorite spot for this clematis - a focal point planted around my mailbox.
