Clematis 'Isago'
Clematis 'Isago' is a captivating perennial vine that offers a spectacular, extended bloom season. Its luxurious 4–5 inch flowers appear twice yearly, first as fully double blooms in late spring, then as semi-double to single blossoms in late summer. This medium-growth vine thrives in rich soil with consistent moisture and shade at its roots, making it ideal for vertical gardening on fences or trellises. For best visual impact, plant against a dark background. This Group 2 Clematis blooms on both old and new wood, providing continuous color interest.
