 🌸 Meet Hardy Gladiolus byzantinus, a garden favorite with a little wildflower flair! Also known as Byzantine Gladiolus, this perennial produces gorgeous spikes of rosy-magenta, funnel-shaped blooms that bring a pop of color and a touch of cottage-garden charm to your landscape.

Unlike the traditional gladiolus you might be used to, this hardy variety can return year after year, gradually multiplying into fuller clumps over time. Its slender, sword-like foliage adds a fun architectural touch even when it's not in bloom, and those vibrant flowers are sure to catch your eye in late spring to early summer!
