The Story
Plant Bio
Agapanthus praecox, commonly known as Lily of the Nile, is a clump-forming perennial from South Africa, featuring strap-like, evergreen to semi-evergreen leaves and large, rounded umbels of funnel-shaped flowers on tall, leafless stalks. A particularly robust and free-flowering cultivar, 'Storm Cloud' is distinguished by its large, dramatic flower heads of deep, dark violet-blue flowers held on strong, upright stems. It is a taller variety than many modern compact hybrids.
