BIG & BEAUTIFUL! Mixed colors. Our mix offers an enormous color range, including the most delicate pastels, bold hues and almost unimaginable bicolors. Their sword-like foliage and tall, impressive flower spikes, make striking accents in the mixed flower border. Glads are easy to grow, requiring only full sun and good drainage. Hardy in zones 8-11; elsewhere treat as an annual, or dig them in the fall and store over winter.
