montbretia 'Vulcan'


The 'Vulcan' variety of Crocosmia is a striking perennial plant that is admired for its vibrant floral display and elegant foliage. The plant features long, arching stems that are adorned with slim, sword-shaped leaves, which are a rich green in color and present a graceful, linear appearance. As the plant matures, it produces showy sprays of flowers that tend to bloom from the bottom up along the stem's length. The flowers of the 'Vulcan' Crocosmia are truly the centerpiece of the plant's beauty. They exhibit bold, fiery hues ranging from a rich red to a deep orange, creating a warm and intense display that can catch the eye from afar. Each trumpet-shaped flower shows off a flared and slightly ruffled edge, which adds to their dramatic allure. The inside of the blossoms may reveal a throat with a lighter shade or contrasting color, often yellow or golden, which further accentuates the flower's beauty. These fiery blooms are arranged in branched clusters, also known as inflorescences or flower spikes, that gracefully bend over at the tips due to the weight of the flowers, lending the plant an elegant and cascading effect. The overall appearance of the Crocosmia 'Vulcan' is one of vibrancy and movement, as if the blooms were emulating flames dancing in the breeze. This plant can serve as a vivid addition to gardens, attracting pollinators like hummingbirds and butterflies while providing a dazzling splash of color in borders, beds, or as cut flowers in arrangements. Its summer blooming period adds to the garden's interest during a season when many other plants have already finished their floral show.

  • water dropWater

    The Montbretia 'Vulcan' should be watered deeply to saturate the root zone, generally this means applying approximately 1 inch of water. This deep watering promotes strong root growth. During the active growing season in spring and summer, water once a week, especially in the absence of sufficient rainfall. Cut back on watering as the plant goes dormant in the late fall and winter; during this time, you may only need to water every 2-3 weeks, if at all, depending on the climate. Always check the top inch of soil for moisture before watering to avoid over-watering.

  • sunLight

    Montbretia 'Vulcan' thrives in full sun, which means it should receive at least 6 hours of direct sunlight each day for optimum growth and bloom. The best spot for the plant would be an area that is protected from strong winds but has unobstructed exposure to the sun. If grown in too much shade, the plant may not produce as many flowers and can become leggy.

  • thermometerTemperature

    Montbretia 'Vulcan' prefers moderate temperatures and grows best in zones 5 through 9. The plant can withstand minimum winter temperatures down to about -20 degrees Fahrenheit. During the growing season, a temperature range between 60 and 80 degrees Fahrenheit is ideal for this plant. Extreme temperatures above 90 degrees Fahrenheit may stress the plant, while temperatures below 15 degrees Fahrenheit may damage or kill the corms.

  • scissorsPruning

    Montbretia 'Vulcan' benefits from pruning to remove spent flower stems and encourage reblooming. Deadhead faded flowers consistently throughout the blooming period. In late fall or early winter, after the foliage has died back, cut the plant down to the ground to tidy up the garden and remove any diseased or dead plant material. Pruning is typically done once a year at this time.

  • circleLife cycle

    Crocosmia 'Vulcan,' also commonly known as Montbretia 'Vulcan', begins its life as a corm, a bulb-like underground storage organ, which sprouts in spring. As temperatures warm, foliage emerges, forming sword-shaped green leaves and establishing the plant's presence. During the summer, Montbretia 'Vulcan' produces stems that bear vibrant red to orange funnel-shaped flowers, attracting pollinators such as hummingbirds and bees, and providing aesthetic value. After flowering, the plant sets seed, although in many cultivated varieties, including 'Vulcan,' sexual reproduction is often less viable, and they primarily propagate vegetatively through corm offsets. In the fall, the foliage dies back with the onset of cooler temperatures, and the corm enters a period of dormancy throughout the winter. The dormant corms conserve energy to resprout the following spring, thereby completing the life cycle and continuing the plant's perennial growth pattern.

      Spring to Summer

    • The most popular method of propagation for Crocosmia ‘Vulcan’, commonly known as montbretia, is by dividing its corms. The best time to do this is in the spring, after the last frost date when the soil has warmed up. To propagate, dig up the clump of corms and gently separate them into smaller clusters. Each cluster should have at least one growing point. Replant the corm clusters at a depth of approximately 3 to 5 inches (7.5 to 12.7 centimeters) and space them about 6 to 8 inches (15.2 to 20.3 centimeters) apart in well-drained soil. Water the newly planted corms thoroughly to encourage root development. With this method, montbretia can quickly establish itself and start to bloom in the following flowering season.
