Byzantine Gladiolus

This is not your average gladiolus! Introducing Byzantine Gladiolus, a new addition to our already stellar lineup of traditional glads and other unique perennial plants. This striking heirloom glad features small, vivid magenta blooms that closely resemble orchids. Loads of these bright flowers cover tall, strong yet graceful spikes that never need staking. They make exceptional floral displays in full sun to part shade sites, such as mixed borders, seasonal cutting gardens and naturalized feature beds. Byzantine Gladiolus is easy to grow and is one of the most cold-hardy glads on the market. Plant in well-drained soil for best results.
