sword lily 'Prima Verde'


Gladiolus 'Prima Verde', commonly known as the sword lily due to its long, pointed leaves, exhibits a striking appearance. The plant has tall, upright flower spikes known as inflorescences that are adorned with multiple trumpet-shaped flowers. These blooms are nestled closely together, each emerging from its own narrow sheath along the stem. 'Prima Verde' specifically is known for its vibrant green blossoms, a unique and eye-catching hue for gladioli. The color is a fresh, lively shade of green, which stands out in garden settings and floral arrangements. Its foliage consists of sword-shaped leaves that grow at the base of the plant, forming a fan-like pattern. The leaves are a deep, rich green color, creating a lovely contrast with the lighter-toned green of the flowers. The overall appearance is a combination of elegance and exotic allure, which is why Gladiolus 'Prima Verde' is a popular choice for gardens and as a cut flower for bouquets and displays.

  • skullToxicity

    • To humans

      Gladiolus is not considered highly toxic to humans, but it can be mildly poisonous if ingested. Eating parts of the plant, particularly the corms (bulb-like structures), can cause symptoms such as nausea, vomiting, abdominal pain, and diarrhea due to the presence of certain alkaloids and saponins. Skin contact with the plant can sometimes result in contact dermatitis for sensitive individuals. It is generally recommended to avoid ingesting parts of the gladiolus plant and to handle it with care if you have sensitive skin.

    • To pets

      Gladiolus is considered mildly toxic to pets such as cats and dogs. If a pet ingests parts of the plant, especially the corms, it could experience symptoms such as drooling, vomiting, diarrhea, lethargy, and abdominal pain. The toxic compounds in gladiolus, which include alkaloids and saponins, are the cause of these symptoms. If you suspect your pet has ingested gladiolus, it is important to contact a veterinarian for advice on the appropriate course of action.

  • water dropWater

    Gladiolus, commonly known as the sword lily, requires consistent moisture especially during the growth and blooming periods. Water the plant deeply once a week, providing about 1 to 1.5 gallons for each plant to ensure the soil is thoroughly moistened to a depth of about 9 inches. In periods of hot, dry weather, additional watering is needed to keep the soil from drying out completely. Be careful to avoid overwatering as standing water or overly wet soil can cause bulb rot. Reduce watering once the blooming period is over and the leaves begin to yellow and die back.

  • sunLight

    Gladiolus thrives in full sun conditions, meaning at least 6 hours of direct sunlight per day. The best spot for the sword lily is in a garden area that is not shaded and receives uninterrupted sunlight throughout the day. Avoid planting them in areas that are heavily shaded as this can impact flower production and bulb health.

  • thermometerTemperature

    The sword lily prefers warm conditions and is hardy to USDA zones 7 through 10. Gladiolus can survive minimum temperatures of around 40 degrees Fahrenheit, but they grow best when daytime temperatures are between 60 to 80 degrees Fahrenheit. If the temperature dips below freezing, the bulbs should be dug up and stored in a cool, dry place during the winter.

  • scissorsPruning

    Pruning gladiolus involves removing spent flower spikes to encourage the plant to direct energy into bulb development rather than seed production. Deadheading, or cutting the flower stalks after blooming, should be done as soon as flowers begin to fade. Leave the foliage in place until it has died back naturally to allow energy to return to the bulbs for next year's growth. Prune during the mid to late summer once the plants have finished their blooming cycle.

    The Sword Lily, or Gladiolus 'Prima Verde', thrives in a well-draining and nutrient-rich soil mix. A blend of two parts loam, one part sand or perlite, and one part compost or peat is ideal. The pH should be slightly acidic to neutral, ranging from 6.0 to 7.0 for optimal growth.

    Sword Lilies, or Gladiolus 'Prima Verde', are generally grown from corms which should be planted annually. After the growing season, the corms can be dug up, stored, and then replanted in the spring.

    Sword Lilies prefer moderate humidity levels but are quite adaptable. To achieve the best growth, aim for a relative humidity of around 40-60%.

  • circleLife cycle

    The life cycle of the Sword Lily, Gladiolus 'Prima Verde', begins when a corm, an underground storage organ, is planted in the soil typically in the spring. After planting, the corm sprouts, and roots and shoots begin to develop, growing into green, sword-shaped leaves. The plant then develops a tall flower spike, adorned with funnel-shaped flowers that can bloom in succession from the bottom up. Following the flowering stage, if pollination occurs, the plant can produce seeds; however, most reproduction is done vegetatively through the corms. As the growing season ends, the foliage dies back, and the corm enters a dormancy period, conserving energy for the next season. The next year, the cycle restarts as new cormlets that have developed from the parent corm are detached and planted to grow new plants.

      Spring to Summer

    • Propogation: The most popular method of propagating the Gladiolus 'Prima Verde', commonly known as the Sword Lily, is through corms, which are specialized swollen stem bases. The best time to plant these corms is in the spring, after the danger of frost has passed, so they can establish themselves during the warmer growing season. To propagate, select healthy corms and plant them about 4 to 6 inches (10 to 15 centimeters) deep and about 6 inches (15 centimeters) apart in well-drained soil with good sun exposure. It is essential to ensure that the pointed end of the corm is facing upward. After planting, water the corms thoroughly to settle the soil around them. As the plants grow, they will produce new corms, which can be harvested and stored in a cool, dry place during winter for planting in the following season.
