Glamini® Gladiolus Silvia's warm, golden-yellow flowers are a spectacular addition to the summer garden. Growing 24-26" tall, this gladiolus variety is half the height of the old-fashioned glads, but still stands out at a distance. Since Glaminis are so short and naturally sturdy, they don't need to be staked, making them perfect for mixed borders, annual beds, tropical gardens, and even containers. Give them plenty of sun, well-drained fertile soil, and plant a batch of bulbs every other week in early spring for continuous gorgeous blooms. Deer tend avoid. Lift in the fall in zones 3-7.
