sword lily 'Green Star'


Gladiolus 'Green Star' is a striking plant known for its showy, vibrant blooms. The flowers are a vivid lime-green, which is a color rarely seen in the gladiolus family. They are arranged in a classic sword-like spike, which gives the gladiolus its name from the Latin word for "sword." Each flower spike bears multiple trumpet-shaped blossoms that open in succession from the bottom up. These green blossoms are often accented by a delicate white throat, adding contrast to the individual flowers. The leaves are long, slender, and sword-shaped, complementing the tall flower spikes with their linear form. They are a bright green in color, which provides a lush backdrop for the dramatic flower spires. The overall effect of the Gladiolus 'Green Star' is a striking vertical element with a refreshing palette that stands out in any garden display.

  • water dropWater

    Sword lilies, including the Gladiolus 'Green Star', should be watered deeply once a week, providing about 1 to 1.5 inches of water each time to ensure the soil stays moist but not waterlogged. During hot, dry spells, increase watering frequency to maintain consistent soil moisture. Allow the top 2 inches of soil to dry out between waterings to avoid overwatering which can lead to bulb rot. It's best to water early in the morning to reduce evaporation and prevent disease. For potted sword lilies, water until you see excess water running from the drainage holes, indicating the soil is thoroughly moistened.

  • sunLight

    Sword lilies thrive in full sun, which means they need at least 6 to 8 hours of direct sunlight per day. Position them in a spot where they will receive plenty of light without being shaded by taller plants or structures. They can tolerate partial shade but flowering may be compromised. The ideal location is in an open area that is not obstructed from the sun's rays for most of the day.

  • thermometerTemperature

    Sword lilies prefer temperatures within the range of 60-80 degrees Fahrenheit and can tolerate a minimum temperature of around 50 degrees Fahrenheit. To encourage flowering, maintaining temperatures within this range is ideal. They are not tolerant of frost, so in areas with cold winters they need to be dug up and stored inside or protected with mulch.

  • scissorsPruning

    Prune sword lilies by removing spent flower spikes just above the leaves to encourage the remaining buds to open and to maintain a neat appearance. Prune damaged or yellowing leaves at the base. The best time for pruning sword lilies is after they have finished flowering, typically in late summer or early fall. Regular pruning also helps prevent diseases by promoting good air circulation.

  • bambooSoil

    Sword Lily 'Green Star' thrives in a well-draining soil mix consisting of two parts loam, one part sand or perlite for drainage, with an added amount of organic matter like compost. The ideal pH range for the soil should be slightly acidic to neutral, between 6.0 to 7.0.

  • plantRepotting

    Sword Lilies do not require frequent repotting; they are typically annuals grown from corms which are planted anew each spring. After flowering, corms are lifted, dried, and stored for the next season.

  • circleLife cycle

    The 'Green Star' Gladiolus begins its life as a corm, a bulb-like underground storage organ, which is typically dormant through the winter. In the spring as temperatures rise, the corm sprouts and forms a sturdy spike with narrow, sword-shaped leaves and begins to develop flower buds. Throughout the summer months, the flowering stalk elongates and the trumpet-shaped flowers bloom in succession from the bottom up in shades of green and cream. After flowering, the plant focuses on photosynthesis and the replenishment of the corm for the next season. As autumn approaches, the foliage yellows and dries as the plant goes into dormancy. Over winter, the corm rests until favorable conditions return, when it can begin the cycle anew with the growth of a new shoot.

      Spring to Summer

    • Gladiolus 'Green Star', commonly known simply as gladiolus, is commonly propagated through the division of its corms. The best time for this is after the flowering has finished and the foliage has died back, which is typically in late summer or early fall. Once the corms are dug up, they can be separated, and the offsets, which are the small corms attached to the base of the parent corm, can be detached. These offsets can be stored in a cool, dry place over the winter and then planted about 4 to 6 inches (10 to 15 centimeters) deep in well-draining soil in the spring, when the threat of frost has passed. This ensures that the new plants have sufficient time to establish themselves during the growing season.
