  • water dropWater

    Gladiolus 'Las Vegas,' commonly known as Sword Lily, requires moderate watering. During the active growth period in spring and early summer, water the Sword Lily once a week with about 1 gallon of water per plant, ensuring that the soil is moist but not waterlogged. As the flower spikes develop, you may need to increase watering. After blooming, reduce the frequency of watering to allow for a period of dormancy. It's crucial to avoid overwatering, which can lead to bulb rot.

  • sunLight

    Sword Lily thrives best in full sunlight conditions. Planting them in a location that receives at least 6 hours of direct sunlight per day will result in robust growth and optimal flowering. Avoid shady spots, as inadequate light can lead to weak plants and poor blooming.

  • thermometerTemperature

    Sword Lily prefers warm temperatures and grows best in a range between 60°F to 90°F. The plant can withstand minimal temperature drops but is not frost-tolerant; it should not be exposed to temperatures below 40°F. Ideally, maintain the garden area within these temperature ranges for healthy growth.

  • scissorsPruning

    Pruning Sword Lily involves removing spent flower spikes to encourage more blooms and to prevent the plant from using energy to set seeds. Cut the flower stalk down to the base after the flowers have faded, which is typically once the blooming season ends in late summer. Annual removal of old, non-productive corms in the early spring is also recommended to promote vigorous growth.

  • circleLife cycle

    The Gladiolus 'Las Vegas', also known as the Sword Lily, begins its life cycle when a corm, a type of bulbous storage organ, is planted in fertile, well-drained soil during spring after the threat of frost has passed. The corm germinates, sending up sword-like foliage and a tall flower spike as it enters the vegetative growth stage, drawing nutrients and energy from the soil and sun. During the flowering stage, which occurs in the summer months, brightly colored blooms appear along the flower spike, attracting pollinators and possibly leading to seed formation if flowers are fertilized. After flowering, the plant enters a period of senescence; the foliage turns yellow and dies back as the plant redirects energy back into the corm for dormancy. Throughout the dormant stage, the corm rests underground during fall and winter, conserving energy for the next growing season. The cycle begins anew when environmental conditions are favorable, with the existing corm producing new shoots or new corms developing from the base of the old one to produce fresh growth.

      Spring to Summer

    • The most popular method of propagating Gladiolus 'Las Vegas', commonly known as the Gladiolus, is through its corms. Propagation is typically done in the spring after the threat of frost has passed. Gardeners dig up the corms, which are swollen underground stems that store energy for the plant. Each corm can produce multiple plants. To propagate, the old corm from the previous year is removed from the bottom of the new one. The new corms, along with any small cormels that have formed, are then planted about 4 to 6 inches deep (about 10 to 15 cm) and spaced 5 to 6 inches apart (about 12 to 15 cm). They should be placed in well-draining soil with good sunlight to ensure the best growth and flower production.
