Wayside Gardens Gladiolus Passos Bulbs

These gladioli reach a mature height of up to 58 inches. Given their significant height, it is recommended to stake them or plant them in a sheltered area to prevent the tall flower spikes from toppling over in strong winds.

Yes, 'Passos' is well-suited for containers. Ensure your pot is deep enough to accommodate the 4-inch planting depth and has excellent drainage to prevent the bulbs from rotting.

In zones colder than 7, these bulbs are not winter-hardy. You can still enjoy them as annuals, or dig up the bulbs in the fall after the first frost, store them in a cool, dry place, and replant them in the spring.

For the longest-lasting arrangements, cut the spikes when the bottom one or two florets begin to open. The remaining buds will continue to open sequentially once placed in a vase.

While they thrive in full sun, they can also tolerate partial shade. Providing at least six hours of direct sunlight daily will yield the most robust spikes and the most vibrant coloration.

Each order contains 12 Gladiolus 'Passos' bulbs, which is an ideal quantity for creating a dense, high-impact grouping in a garden bed or a large container display.
