The sword of a gladiator was known as a gladio, and it probably resembled the leaves or floral spikes of gladiolus. These narrow and pointed leaves stand nearly vertical, angling only slightly to the left and right of a single flower stalk that can get as tall as six feet. The floral spike supports several very colorful florets that are arranged to the left and right, but tend to lean toward the front.
The summer bloom can be red, pink, orange, yellow, greenish yellow or white, in bright or pastel hues, and often with multiple colors. Florets bloom upward from the bottom, so lower florets fade before upper florets open. Gladiolus is an excellent cut flower anyway. Taller blooms might need to be staked.
New bulbs should be planted about now, at least four inches deep, and about four or five inches away from each other. Gladiolus want well drained soil and full sun exposure.
