Gladiolus, often affectionately shortened to “glads,” is a genus of perennial flowering plants prized for its tall, sword-like foliage and dramatic, densely packed flower spikes. The genus includes roughly 300 recognized species, the vast majority native to southern and central Africa, along with hundreds of additional cultivated hybrid varieties developed over more than a century of breeding. A single gladiolus stem can carry between 12 and 20 individual blooms in the largest cultivars, opening in succession from the bottom of the spike upward over a period of several weeks.
Gladiolus plants grow from round, symmetrical corms rather than true bulbs, and a healthy corm typically reaches flowering size within about 10 to 12 weeks of planting. Height varies considerably by type, with the largest grandiflora hybrids reaching 3 to 4 feet tall and producing flowers up to 6 inches across, while dwarf and nanus types stay closer to 18 to 24 inches with more modestly sized blooms. Because of their height and top-heavy flower spikes, taller gladiolus varieties often require staking to prevent the stems from bending or snapping in wind and rain.
Color range across the genus is extraordinarily broad, spanning pink, purple, red, yellow, green, white, and orange, along with a large number of bicolor and tricolor combinations that display contrasting throat markings or petal edging. Ruffled and heavily textured petal forms have become increasingly popular in modern breeding, adding visual complexity to what was traditionally a smoother, more uniform flower shape. Gladiolus corms also multiply steadily underground, with a single planted corm capable of producing several new cormlets around its base by the end of a single growing season.
Bloom timing depends heavily on planting schedule, since gladiolus corms are typically planted in succession from spring through early summer to extend the overall flowering window into fall. Most gladiolus varieties are hardy as perennials only in zone 7 and warmer, meaning gardeners in cooler regions commonly dig up and store corms indoors over winter before replanting them the following spring. As popular cut flowers, gladiolus stems can last 7 to 8 days in a vase when properly conditioned, making them a longstanding favorite for both garden borders and floral arrangements. Below are 50 different types of gladiolus, each known for its own color, size, or growth habit.
Types of Gladiolus
Priscilla
Priscilla is a tricolored cultivar featuring a white background with pink-edged petals and a soft yellow throat, with more than a dozen florets typically arranged along a single strong, erect spike. This variety performs well in both garden borders and container plantings, thriving in full sun with plenty of water during the growing season. Priscilla can also tolerate partial shade, making it more adaptable than many other large-flowered gladiolus types.
Traderhorn
Traderhorn produces heavy flower stalks that typically require staking, since the weight of the blooms can cause the stems to flop without support. This variety is easily grown from corms and thrives in full sun, remaining hardy in zones 7a through 10b. Traderhorn’s corms benefit from being dug up and stored indoors in colder climates.
Claudia
Claudia is a hot, deep red variety that is not among the tallest gladiolus types, making it well suited to natural planting schemes rather than formal, staked borders. This cultivar pairs particularly well with cannas and dahlias for a striking late-summer garden display. Claudia is typically planted between March and May for blooms from July through October.
David Hills
David Hills displays warm apricot and orange tones that make it a strong fit for mixed borders alongside other warm-toned summer perennials. This variety is a popular choice for cutting gardens thanks to its reliable stem strength and vibrant coloring. David Hills blooms during the peak of the summer gladiolus season.
