Evening gladiolus Gladiolus tristis
ABOUT
The Gladiolus tristis, commonly known as the evening gladiolus, is a distinctive and charming flowering plant. This species is noted for its elegant and tall flower spikes, which bear a stunning sequence of closely packed blooms. The flowers themselves are typically a creamy-yellow color that can sometimes age to a soft brownish hue. Each bloom exhibits a delicate and alluring fragrance, especially noticeable in the late afternoon and evening, hence the common name evening gladiolus. The petals of the evening gladiolus are unique; they have a trumpet-like shape with a subtle funnel form, characterized by their ruffled or wavy edges, which adds to their visual interest and charm. The individual blossoms are comprised of six tepals - three outer segments and three inner segments, which may sometimes display faint greenish or purple streaks or markings, adding to the plant’s beauty. The foliage of the evening gladiolus consists of sword-shaped leaves, which are narrow and linear, perfectly complementing the vertical silhouette of the flowering stalks. These leaves are a vibrant green color, which contrasts attractively with the creamy blossoms. The foliage grows in a fan-like pattern that radiates from the base of the plant, providing a lush backdrop for the flowers. Adding to its ornamental value, when in bloom, this plant provides an excellent visual display that is often used in cut flower arrangements because of its noteworthy appearance and delightful scent. It is a popular choice for gardens where its blooms can be enjoyed during the evening hours, filling the air with its heady fragrance.

WaterThe Night Gladiolus should be watered deeply once a week, ensuring that the soil is moist but not waterlogged. During the growing season, provide about 1 gallon of water per square foot of soil. Cut back on watering as the flowers begin to die back, and once the foliage has died down after flowering, withhold water entirely to allow the corms to rest in dry soil.
LightThe Night Gladiolus thrives best in full sun conditions. It should be planted in a spot that receives at least 6 hours of direct sunlight daily. Avoid placing it in full shade, as insufficient light can inhibit growth and reduce flowering.
TemperatureThe Night Gladiolus prefers a temperate climate with temperatures ranging from 50°F to 70°F. It can withstand minimum temperatures down to about 35°F, but freezing temperatures can damage the plant. The ideal temperature range encourages optimal growth and blooming.
PruningPrune Night Gladiolus to remove spent flower stalks to encourage more blooms and prevent seed formation. Pruning should be done immediately after the flowers fade. The best time for pruning the Night Gladiolus is in the late summer or early fall when the flowering has ceased.
CleaningAs needed
SoilNight Scented Gladiolus requires well-draining soil with a mix of loam, sand, and compost to mimic its natural environment. The ideal soil pH should be slightly acidic to neutral, around 6.0 to 7.0.
RepottingNight Scented Gladiolus corms should be lifted and stored after flowering and replanted the following spring; therefore, they are repotted annually.
Humidity & MistingThe Night Scented Gladiolus thrives in typical outdoor humidity levels but does not require any special humidity adjustments when grown outside in its preferred climate.
Suitable locationsIndoor
Ensure bright light and good air circulation for Night Scented Gladiolus.
Outdoor
Plant in sun, well-drained soil; mulch in zones under 8 USDA.

Life cycleGladiolus tristis, commonly known as "night gladiolus," begins its life cycle as a corm, which is an underground storage organ containing the embryonic plant. After a period of dormancy, typically triggered by seasonal changes, the corm sprouts in late winter to early spring, developing roots and shoots. The shoot grows into a tall, sword-shaped foliage, and the plant eventually produces fragrant, creamy-yellow flowers that typically bloom at night in late spring. Pollination of the flowers by nocturnal insects allows for the development of seeds. Once the flowering is finished, the plant enters a period of senescence; the foliage dies back, and the corm enters another dormancy phase during the hot, dry summer months. The corm can give rise to new plants either by seed dispersal or vegetatively, as the corm can produce small offsets which will grow into new plants the following season.
PropogationPropogation time
Spring to early summer
The most popular method to propagate Gladiolus tristis, commonly known as the evening gladiolus, is through corms, which are the plant’s bulb-like storage organs. These should be planted in the spring after the last frost when the soil has warmed up to at least 55 degrees Fahrenheit (about 13 degrees Celsius). Plant the corms about 3-4 inches (7.5-10 cm) deep, and around 6 inches (15 cm) apart in a sunny location with good drainage. As they grow, ensure that the plants are well-watered during dry spells and provide support for the flower stalks if necessary. After flowering, let the foliage die back naturally before digging up the corms, which can be stored in a cool, dry place and replanted the following spring.
