Montbretia (Crocosmia 'Lucifer')
Explosive scarlet blooms define Montbretia, Crocosmia 'Lucifer'. A striking Iridaceae bulb, indispensable for summer color contrast.
Complete Plant Information
Overview
Crocosmia ‘Lucifer’ stands out in the summer garden with its fiercely brilliant, scarlet-red blossoms. This Alan Bloom hybrid, often referred to by its common name Montbretia, offers vertical accent and tropical heat, making it instantly recognizable. Its gladiolus-like foliage provides excellent texture even when not in bloom.
This cormous plant thrives when situated where its vibrant color can be best appreciated against cooler greens or blues. While categorized as a bulb, proper winter care is essential, especially at the colder edge of its hardiness range. The strong, upright flower scapes of Crocosmia ‘Lucifer’ deliver reliable color from mid-summer well into August.
For gardeners seeking high-impact color and excellent material for fresh arrangements, Montbretia is a superb choice. Its dramatic presentation adds necessary contrast to traditional perennial borders, ensuring the garden remains dynamic during the peak heat of the season.

How to Grow
Plant the corms of Crocosmia ‘Lucifer’ in the spring, ensuring this occurs only after all danger of frost has passed in your region. Successful cultivation requires medium-moisture, moderately fertile, and crucially, well-drained soil. Space the corms approximately 6 inches apart and bury them around 3 to 4 inches deep.
During the growing season, aim to maintain medium soil moisture, especially when the plant is actively developing its fantastic scarlet flower spikes. While Crocosmia ‘Lucifer’ strongly favors full sun for the best bloom performance, consider planting it where it receives afternoon shade if you garden in extremely hot summer climates, which prevents scorching.
Maintenance is generally moderate. Be aware that rabbits may find the foliage appealing, so protection might be necessary. For guaranteed winter survival, particularly in Zone 5, gardeners should plan to lift the corms in autumn after foliage dies back. Store them in a dry medium, much like gladiolus, in a cool, frost-free location until the following spring planting season.
Landscape Uses
Montbretia is most impactful when naturalized or planted formally in substantial groups. The recommendation is to plant clumps of at least 12 individuals to create a bold sweep of color that effectively contrasts with other border residents. Its vertical habit makes it perfect for plugging gaps or adding height midway through a mixed perennial border.
Because it forms dense clumps, Crocosmia ‘Lucifer’ works well as a mid-scale structure plant in the landscape. If you anticipate needing to lift the corms for winter storage, growing this variety in containers is a convenient alternative, streamlining the end-of-season care routine. It also serves as a high-quality, showy specimen for cutting gardens due to its excellent performance as a good cut flower.

Noteworthy Characteristics
Crocosmia is a genus of about 7 species of cormous plants originating from the grasslands of South Africa. They are widely esteemed as good fresh cut flowers frequently incorporated into professional floral arrangements. The genus name originates from Greek words, krokos (saffron) and osme (a smell), referencing the scent of dried flowers steeped in warm water. ‘Lucifer’, specifically, is an Alan Bloom hybrid known for its foliage and flowers reminiscent of gladiolus. It forms dense clumps featuring tubular, nodding, one-sided flowers of brilliant scarlet red borne along stiffly arching flower stems reaching up to four feet tall.
Tolerances
Potential Problems
The primary concern regarding the foliage of Crocosmia ‘Lucifer’ involves spider mites. These pests can cause considerable damage, leading to discoloration and impairing the plant’s ability to flower normally if an infestation is left unmanaged. Regular inspection, especially during hot, dry spells, is crucial for early detection.
Another significant issue is herbivory; rabbits often browse the foliage enthusiastically. Consuming the leaves directly impedes the plant’s photosynthetic ability, which in turn restricts the energy stored in the corms, negatively impacting next year’s performance and blooming potential. Implementing physical barriers or repellent strategies early in the season may be necessary where rabbits are numerous.
Frequently Asked Questions
What hardiness zones is Montbretia suitable for?
Crocosmia ‘Lucifer’ is generally hardy in USDA Zones 5 through 9, though extra winter protection like heavy mulching is recommended for survival at the colder end of this range.
How large does Montbretia grow?
This striking variety typically achieves a mature height between 2 and 4 feet, with a modest spread of 1 to 2 feet at maturity.
What sun exposure does Crocosmia ‘Lucifer’ need?
For the most intense scarlet coloration and robust growth, Crocosmia ‘Lucifer’ requires full sun. However, it will tolerate light or partial shade, particularly appreciated during intense summer heat.
When does Crocosmia ‘Lucifer’ bloom?
This plant delivers its fiery display of scarlet red blooms steadily throughout the summer months, generally blooming from June right through August.
Conclusion
Crocosmia ‘Lucifer’ is an essential performer for adding vertical interest and explosive, warm color to the mid-to-late summer garden. Whether used in drifts or containers, the unique structure and brilliant hue of this Montbretia variety ensure high visual impact. Always check your local climate to confirm that USDA Zone 5-9 compatibility matches your growing conditions before planting your corms this spring.
Companion Planting
When designing a border around Crocosmia ‘Lucifer’, selecting complementary shapes and colors enhances its dramatic presentation. Pair the upright, fiery spikes with plants that offer softer textures or cooler tones, such as blues and purples. Consider planting near Salvia nemorosa cultivars or softer purple Nepeta for textural contrast that complements the tubular, scarlet flowers.
The moisture requirements of Montbretia are medium, making it a good partner for many classic perennials that appreciate consistent watering but demand sharp drainage. Avoid planting with extremely drought-tolerant species, as Crocosmia ‘Lucifer’ may struggle if allowed to dry out excessively during its peak growth phase.
Seasonal Care Calendar
Spring is the critical time for planting Crocosmia ‘Lucifer’ corms, ensuring they go into the ground after the final frost. Focus on providing well-drained soil mixed with some aged compost to encourage strong root development for the season ahead. Water regularly but avoid saturation as new shoots emerge.
Summer maintenance centers on enjoying the spectacular bloom time from June to August. Deadheading spent flower scapes is not strictly necessary but can help tidy the plant and redirect energy. Keep soil consistently moist during dry spells to support the high water needs of the developing foliage and flowers.
In autumn, address winter preparation based on your hardiness zone. If overwintering ‘Lucifer’ in place (Zones 7-9), apply a thick layer of protective mulch once the foliage begins to die back. For colder zones (5-6), plan to lift the corms before the ground freezes completely to ensure their survival until the next planting season.
