Lilies are a type of long-stemmed perennial bulbous plant that produce stunning large flowers. Not all types of lilies have scented flowers. Lilies are classified into 9 main categories or divisions. Different types of lilies in these divisions have their own characteristics.
True varieties of lilies belong to the Lilium plant genus and grow from bulbs. Depending on the species of lily, these leafy flowering plants grow between 2 and 6 ft. (0.6 – 1.8 m) tall.
Lily Flowers
Lily flowers can be classified by flower form and flower aspect. Many lily flowers look like long funnels with large petals (tepals). Other types of lily flowers have petals that turn back on themselves (recurved tepals) such as the Turk’s-cap lily. Generally, lily flowers are divided into 3 aspects: down facing, out-facing, and up-facing.
The shape of lily flower can be trumpet-like facing upwards (left), or curved outside and facing downwards (right)
About Lilies
There are about 100 species of lilies in the genus Lilium.
The most popular kinds of lilies are hybrids in the Oriental, Asiatic, and Trumpet lily divisions.
Many plants have “lily” in their common name but they are not true lilies as they are not in the genus Lilium. For example, daylily is not a true lily as it’s a member of the genus Hemerocallis. Lily of the valley is also not a true lily as it’s a member of the genus Convallaria.
According to the FDA, lilies in the genus Lilium as well as daylilies are poisonous to cats. The entire lily plant is toxic: the stem, leaves, flowers, pollen, and even the water in a vase. Many types of lilies are also toxic for dogs and humans.
Types of Lilies: Lily Hybrids and Species
Knowing about all the different types of lily hybrids and flowers can help plan your garden landscape. For example, some varieties of lilies such as the Asiatic lily hybrids bloom earlier than others. Lilies in the Martagon division prefer shade and cooler climate, whereas Trumpet and Aurelian hybrids thrive in full sun and bloom late in the summer.
Here are the different lily plant families and the various types of hybrid lilies:
Asiatic Lilies (Asiatic Hybrid Lilies)
Asiatic lilies (Lilium asiatica), like all lilies, are a perennial type of flowering plant and they are one of the earliest types of lilies to bloom.
If you are looking for lilies that are easy to grow, then Asiatic hybrid lilies are one of your best choices. The tall lily stems can reach up to between 2 and 5 ft. (60 – 150 cm) and thrive in full sun. Also, these types of lily hybrids grow easily in most soil types.
One of the good things about Asiatic hybrid lilies is the number of flowers on each stem. You can expect to get between 4 and 6 large flowers on each Asiatic lily stem. Some Asiatic lily plants have classic lily bowl-shaped flowers and others have striking recurved tepals. Each of these striking flowers can be between 4” and 6” (10 – 15 cm) in size.
Asiatic lily blooms come in a wide variety of colors. Some stunning examples of Asiatic lilies have flowers with deep red and orange colors. Other Asiatic hybrid lilies have more delicate attractive pastel colors. When Asiatic lilies start to flower in June, you can expect the blooms to last until the middle or end of July.
If you want to plant Asiatic lily hybrids in your garden, choose an area where they get full sun. You should make sure that the soil drains well but is kept moist. You can also easily grow these types of hybrid lilies in pots.
Asiatic lilies are USDA hardy in zones 4-9.
Types of Asiatic Lily Hybrids and Cultivars
Orange lily (Lilium bulbiferum or fire lily)
Orange lily (Lilium bulbiferum or fire lily) has large orange-colored flower with triangular-shaped tepals that can grow up to 2.3” (6 cm) long. The unscented flowers on orange lilies are upward facing and the tepals form an attractive star shape. The anthers in the middle of the flower are not very pronounced.
Lilium ‘Navona’
Lilium ‘Navona’ is a type of white lily that produces very large white flowers with recurved petals. The showy white flowers on this Asiatic hybrid lily are up-facing. Contrasting yellow/orange anthers protrude from the flower. These flowers commonly feature in wedding bouquets.
Lilium ‘Black Out’
Lilium ‘Black Out’ is a stunning example of an Asiatic hybrid lily. Its large fiery-red tepals turn to deep red in the center of the bloom. On each long stem grows 4 or 5 upward facing flowers that are some of the darkest types of lily flowers you will find.
Asiatic ‘Pixie’
Lilium Butter Pixie
Asiatic ‘Pixie’ is a dwarf perennial lily hybrid that thrives in full sun and has very large pink, orange, or yellow flowers. Stems on this small Asiatic hybrid lily don’t grow taller than 18” (45 cm) and the upward facing blooms flower between late May and early June.

Martagon Lilies – Martagon Hybrid Lilies (Lilium Martagon)
Martagon hybrid lilies (Lilium martagon) belong to division II of lilies and produce exceptional blooming flowers.
Some Martagon lily hybrids can grow taller than Asiatic lilies with certain cultivars reaching 6 ft. (180 cm) tall. Generally, these lily cultivars produce a number of downward facing small flowers with between 12 and 50 flowers per stem!
Because Martagon lily flowers are strongly recurved, they are commonly called Turk’s cap. Their petals can be a variety of colors that include yellows, reds, pinks, lavenders, whites, and oranges. Some Martagon lily hybrid petals have speckles, others have stripes, and some are just a plain color.
Generally, Martagon lilies grow well in full sun with part shade. These lily plants also grow well in very shady areas so you can also plant Martagon lilies between shrubs or in shady areas of your garden.
Because they are easy to grow, Martagon lily hybrids are also good for the novice gardener.
Martagon lilies are USDA hardy in zones 4-8.
Types of Martagon Lily Hybrids and Cultivars

Candidum (Euro-Caucasian) Lilies – Division III
Lilies in the Candidum hybrid (Lilium candidum) division III are mostly related to European species of lilies. Compared to other classifications of lily hybrids, there are not many types of lilies in this category.
The most notable lily plant of this species is the Madonna Lily which, according to some reports, has been cultivated for over 3,000 years. The Madonna Lily grows to about 4 ft. (1.3 m) tall, and some can even reach 6 ft. 7″ (2 m) high!.
Lilium candidum ‘Madonna lily’
One of the striking features about Madonna Lily plant is its long trumpet-like white lily flowers. The flowers of the Madonna lily have large 6 petals. They can grow up to 3” (8 cm) long and are slightly recurved. This gives the out-facing blossoms a showy look as the long orange anthers point out from the center of the flower.

Depending on where you live in North America, American lily hybrids bloom at different times. In the warmer states, you can expect a variety of delightfully scented flowers in late spring and early summer. In the cooler states and Canada, you may have to wait until July to see your American lily hybrids blooming.
The flowers of American hybrid lilies come in a wide array of colors and petal patterns. Many of the American lilies have recurved petals that dangle down facing the ground. However, some hybrid American lily flowers have a Turk’s caps appearance, whereas others have petals that spread out and seem to reach to the skies.
Most American types of lily cultivars grow well in partial shade and are suitable for planting between shrubs or in wooded areas.
American lily hybrids are hardy in USDA zones 3-9.
Types of American Lily Cultivars and Hybrids

Longiflorum Lilies (Longiflorum Hybrids) – Division V
Easter Lily (Lilium longiflorum) with a white flower
The Easter Lily (Lilium longiflorum) is a large showy lily that has long, white trumpet-like flowers. Lily hybrids in the Longiflorum division generally grow well in full sun and are easier to grow in containers or pots rather than in the garden.
Easter lily flowers are often used as cut flowers in large bouquets. The Easter Lily stems grow between 24” and 36” tall (60 – 90 cm) and each leafy stem can produce a number of long fragrant white flowers.
Although Easter lily variety usually blooms in June or July, with special care, the lily can be ‘forced’ to bloom in the spring around Easter time.
Although the classic Longiflorum lily flower is white, a number of cultivars in varying colors have been developed.
Longiflorum lily hybrids are hardy in USDA zones 4-8.
Types of Longiflorum Lily Cultivars

Trumpet and Aurelian Lilies (Trumpet and Aurelian Hybrids) – Division VI
One of the most stunning and fragrant types of lilies are Trumpet and Aurelian hybrids.
All types of lilies classified as Trumpet hybrids have long funnel-like flowers in varying colors and shades. Trumpet hybrid lily flowers can be down facing, out-facing, or up-facing. Some of the flowers are also bowl-shaped; however, most of Trumpet lily varieties have flowers in the shape of a trumpet.
Depending on the type of Trumpet or Aurelian lily, the flowers can be between 6” and 10” (15 – 25 cm) long. Each long lily stalk can have between 12 and 15 flowers per stalk. So, planting Trumpet or Aurelian lily varieties can create showy flower displays in your garden.
The good thing about planting Trumpet or Aurelian lily hybrids in your garden is that they bloom late in the season. Therefore, you can enjoy wonderful blooms when many other plants have stopped flowering.
Unlike Asiatic classifications of lilies, most lilies in the Trumpet division have sweet-smelling blooms. Due to the fact these lily flowers have a strong scent, they may be too intense to have as cut flowers indoors if you are sensitive to smells.
Trumpet and Aurelian lily hybrids are hardy in USDA zones 4-9.
Types of Trumpet Lilies, including Aurelian Lily Hybrids
Lilium ‘Golden Splendor’
Lilium ‘Golden Splendor’ is a trumpet-flowered lily with large out-facing or down facing yellow flowers. Golden Splendor blooms are very fragrant and you can expect to get up to 20 flowers on each long lily stem.

Oriental Lilies (Oriental Hybrids) – Division VII
Oriental lilies are some of the most popular lilies to grow outdoors. For many people, Oriental hybrid lilies are the lily of choice. This is because these plants have stunning enormous flowers and sweet floral fragrances. However, compared to some other classes of lilies, Oriental hybrids may be trickier to grow.
Lily hybrids in the Oriental division differ from Asian hybrids because the flowers are generally larger and more fragrant. Varieties of Oriental lilies bloom from mid-summer and some may even continue flowering into the fall.
Usually, Oriental lily hybrids have outfacing flowers that are in varying shades of pink, red, orange, and white. However, one exception is the stunning Oriental Stargazer lily which has upward facing flat-faced flowers.
Some species of Oriental lilies can grow between 3 and 5 ft. (0.9 – 1.5 m) tall. Their blooms are among some of the largest of any type of lily.
Oriental lily hybrids are USDA hardy in Zones 3-8.
Types of Oriental Lily Hybrids and Cultivars

Other Hybrids (Interdivisional Hybrids) – Division VIII
Lilium LA Hybrid Samur is a type of interdivisional lily hybrid
Interdivisional lily hybrids are cultivated by crossing types of lilies from different divisions. This results in different kind of lilies, each with their own unique characteristics.
Some of the most popular interdivisional hybrids include:
LA lily hybrids are a cross between Lilium longiflorum and Asiatic lilies. This type of hybrid lily has large flat flowers that are mildly fragrant.
OT lily hybrids are cultivated by crossing Oriental lilies with Trumpet lilies. The flowers of lilies from this type are heavily scented with large, eye-catching trumpet blooms.
LO lily hybrids result from crossing Lilium longiflorum lilies with Oriental varieties. These lily hybrids have strong scents and trumpet-shaped flowers with curved petals.
Most Interdivisional lily hybrids are hardy in USDA zones 3-9 with some hardy in zones 4-8.
Species Lilies – Division IX
Lilies that are in the Species division are native lilies that grow in the wild. These wild lilies are the parents of all the hybrid lilies from the previous 8 divisions of lilies mentioned on this list.
In general, lily hybrids in the lower lily classifications are far easier to grow in gardens or containers than wild, species lilies.
There are also a number of flowering plants with beautiful flowers that have ‘lily’ in their name but are not true lilies. So, it’s good to remember that all true lilies are classified as being in the Lilium genus. Other types of plants such as Calla lilies, water lilies, daylilies, or lily of the valley are not true varieties of lily.
