The iris is admired for its elegant, ruffled petals and striking colours, making it a favourite in gardens and floral arrangements. However, many other flowers share similar petal structures, hues, or growth patterns, leading to frequent misidentifications.
If you've ever spotted a flower that looks like iris but weren’t sure what it was, this guide will help. We’ll explore 30 flowers that resemble irises and highlight their unique characteristics, from petal shape to leaf structure and blooming season.
1. Blackberry Lily
The Blackberry Lily, also known as Iris domestica, is a captivating perennial that stands out with its distinctive features. Unlike traditional irises, its flowers are star-shaped with six flaring petals, typically in vibrant shades of orange adorned with red spots, resembling a leopard's skin.
These blooms appear in mid to late summer, each lasting only a day, but the plant produces a succession of flowers over several weeks. The foliage consists of sword-shaped, medium-green leaves that grow in a fan-like arrangement, reaching up to 10 inches in length.
After flowering, the plant develops pear-shaped seed pods that split open to reveal clusters of shiny black seeds resembling blackberries, hence the common name.
2. African Iris
The African Iris, or Dietes iridioides, is an evergreen perennial admired for its resilience and ornamental appeal. Its flowers are white with yellow and blue markings, resembling a small Japanese Iris.
Each bloom is short-lived, typically lasting only a day, but the plant produces a succession of flowers from spring through autumn, often in two-week intervals. The foliage is composed of narrow, sword-shaped leaves that form fan-shaped clumps, providing a graceful, grass-like appearance.
3. Yellow Flag
The Yellow Flag, or Iris pseudacorus, is a robust aquatic plant native to Europe, western Asia, and northwest Africa. It produces bright yellow flowers that bloom in late spring to early summer, each consisting of three large, drooping sepals and three smaller, upright petals.
The foliage is tall and erect, with sword-shaped leaves that can grow up to 3 feet in length, creating a striking vertical accent in gardens and along pond edges. This iris thrives in moist soils and can tolerate standing water, making it ideal for wetland areas.
4. Japanese Iris
The Japanese Iris, known scientifically as Iris ensata, is celebrated for its large, showy blooms and elegant form. The flowers, which appear in early to mid-summer, are typically flat and can reach up to 8 inches in diameter, showcasing a range of colours from deep purple and blue to white and pink.
The petals are broad and slightly ruffled, giving the flower a delicate, graceful appearance. The foliage consists of narrow, sword-shaped leaves that are taller and more slender than those of many other iris species, adding a refined texture to garden landscapes.
Japanese Irises prefer consistently moist, acidic soils and are often planted near water features to accommodate their moisture needs.
5. Gladiolus
Gladiolus, commonly referred to as "glads," are popular flowering plants known for their tall spikes of blooms and sword-like foliage.
The flowers, which bloom from late spring to early autumn, are funnel-shaped and arranged in a one-sided spike, displaying a wide array of colours, including red, pink, orange, yellow, purple, and white.
Each bloom consists of six petal-like tepals that can be ruffled or frilled, adding to their ornamental appeal. The leaves are long, narrow, and pointed, resembling those of irises, but they tend to be stiffer and more erect.
6. Crocosmia
Crocosmia, often known as montbretia, is a perennial that adds a fiery touch to gardens. Its arching flower spikes bear funnel-shaped blooms in vibrant shades of red, orange, or yellow, differing from the typical iris palette.
The petals are arranged in a slightly asymmetrical fashion, creating a dynamic appearance. The plant's sword-like leaves closely resemble those of irises, but they tend to be narrower and more pliant. Crocosmia blooms from mid to late summer, extending the flowering season beyond that of many irises.
7. Siberian Iris
The Siberian iris is a hardy, long-lived type of beardless iris consisting of clumps of narrow, sword-like leaves and slender stems that reach heights up to 4 feet (1 m). The graceful, grass-like leaves remain attractive long after the flowers have faded.
Siberian irises bloom slightly later than the bearded iris, providing a color bridge to summer perennials. Unlike bearded iris, whose foliage becomes ratty and ugly after the plants finish blooming, Siberian iris maintains its elegant waving foliage through the season, resembling an ornamental grass.
8. Louisiana Iris
Louisiana irises are a group of iris species native to the wetlands of the southeastern United States. They come in a variety of sizes, growing anywhere from 12 to 60 inches tall, as well as a variety of colors.
All varieties are native to the lower Midwest and southern United States. The flowers have the standard iris shape, with three standards and three falls, and lack beards.
9. Dutch Iris
Dutch irises were developed in the Netherlands from parent species native to Spain and Morocco. They are the most popular with florists, but many gardeners have even showier types available to them in their flowerbeds.
The colors of Dutch Irises range from purple to blue, yellow to brown and white to pink, and they bloom late spring into early summer.
10. Blue-eyed Grass
Blue-eyed grass, despite its name, is not a true grass but a member of the iris family. It features delicate, star-shaped flowers in shades of blue or violet, each with a yellow centre, creating a charming contrast. The blooms are smaller than those of typical irises, measuring about 1 to 2 centimetres across.
Its foliage consists of slender, grass-like leaves that grow in clumps, enhancing its grassy appearance. Blue-eyed grass blooms from late spring to early summer, adding a subtle yet beautiful touch to gardens.
11. Daylily
Daylilies are renowned for their vibrant, trumpet-shaped flowers that bloom for just a single day, hence their name. Unlike irises, which typically have a three-petal structure, daylilies display six tepals—three petals and three sepals—that are often recurved.
They come in a wide spectrum of colours, including shades of yellow, orange, red, pink, and purple. The foliage consists of long, arching, grass-like leaves that emerge from the base, forming dense clumps.
Daylilies have an extended blooming period, with different cultivars flowering from late spring to late summer.
12. Orchid Iris
The Orchid Iris, also known as the Fringed Iris, is admired for its delicate, fringed petals that resemble orchid blooms. The flowers are typically pale blue to white, adorned with yellow and purple markings, and measure about 2 inches across.

Butterfly Irises bloom intermittently from spring through autumn, with each flower lasting only a few days, but the plant produces numerous blooms over its long flowering period.
14. Crested Iris
The Crested Iris is a charming, low-growing species native to the eastern United States. It features delicate, pale blue to lavender flowers with a white patch and a yellow or orange crest on each fall (the outer petals).
The blooms are about 1 to 2 inches wide and appear in early spring. Unlike taller bearded irises, the Crested Iris has a dwarf stature, with sword-shaped leaves that are 6 inches long, forming an attractive ground cover.
This species prefers partial shade and well-drained, humus-rich soil, making it ideal for woodland gardens or shaded borders.
15. Yellow Daylily
The Yellow Daylily, also known as Lemon Lily, is a fragrant species distinguished by its bright yellow, funnel-shaped flowers that bloom in late spring to early summer. Each flower has six tepals that open widely, measuring about 3 to 4 inches across.
The plant's foliage consists of narrow, arching, linear leaves that form dense clumps, similar to other daylilies. The Yellow Daylily is valued for its hardiness and ability to thrive in a variety of soil conditions, provided they are well-drained.
16. Spuria Iris
The Spuria Iris is one of the tallest members of the iris family, reaching heights of 3 to 5 feet (90-150 cm).

18. Leopard Lily
The Leopard Lily is a striking perennial native to California, known for its vibrant, downward-facing, orange to red flowers with maroon spots, resembling a leopard's coat. Each bloom has six recurved tepals, creating a turk's cap shape, and measures about 2 to 3 inches across.
The plant's foliage consists of whorled, lance-shaped leaves arranged along tall, erect stems that can reach heights of 3 to 7 feet. Leopard Lilies bloom in early to mid-summer, adding a bold splash of colour to gardens.
