101 Purple Flowers: Complete List With Names And Pictures
Thinking of adding some purple flowers to your garden, but aren't sure which ones to add? There are many different purple flowers you can plant in your garden, which is good news! There are annuals, perennials, and somewhere in between depending on your location or hardiness zone. In this massive guide, we look at our favorite purple flowers you can plant this season, with names and pictures of each!
Contents
Purple flowers can add plenty of contrasting color to a garden. When shades of red, white, pink, and orange dominate, adding a splash of purple is an effective trick that makes your entire display pop. Otherwise, if everything is a variation of the same colors, things quickly become washed out and drab.
That doesn’t mean you shouldn’t have a healthy display of many different species of flowers and assorted colors. But some shades of purple are very dramatic and can really enhance the look of your flower garden.
So the next question becomes, do you plant purple annual flowers, or perennial flowers? This list contains both, but we also have a dedicated list of purple perennial flowers if you aren’t interested in replanting new flowers each year.
With that being said, a big list like this one has its benefits! The following massive list has over 100 purple flowers to help you get the purple, indigo, violet, and lilac blasts of color that you need in your garden, container, or window box. From annual flowers to perennials, we’ve got them all covered with names, pictures, hardiness zones, and basic information on each. Let’s dig in!
Allium Ornamental
Scientific Name: Allium
- Plant Type: Perennial
- Geographic Origin: Eastern, Southwestern North America
- Plant Size: 2-3 feet tall
- Sun Exposure: Part sun to full sun
- Plant Zone: 3-9
The allium genus includes some familiar names like garlic, chives, and onions. There are also alliums, often hybrids, that are grown for their puffy, globular blossoms and long, single stalks. They’re often up to three feet tall, with their large flowers adding their purple hue and some lift to your garden. They hold their blooms for quite a while, and even when they fade, they are easy to spot and unique.
Alpine Betony
Scientific Name: Stachys Monieri
- Plant Type: Perennial
- Geographic Origin: Europe to Western Siberia and the Caucasus
- Plant Size: 18-24 inches tall
- Sun Exposure: Partial shade to full sun
- Plant Zone: 3-4
The Alpine betony comes from the mint family. The leaves are green and leather, and the flowers are spiked and tubular. These drought-tolerant flowers have long stems that shoot upward out of the leaves, terminating in a bright purple (or sometimes pink) flower. They attract plenty of pollinators. Animals like rabbits and deer tend to avoid them, so they are good for planting as a defensive border.
Anemone
Scientific Name: Anemone coronaria
- Plant Type: Herbaceous Perennial
- Geographic Origin: Temperate and subtropical locations throughout Europe and the Americas
- Plant Size: 12 inches or less, with 1-inch flowers
- Sun Exposure: Partial to full shade
- Plant Zone: 5-8
Anemones have thick, velvety leaves, usually clustered in groups of three. A trio of leaves gives rise to a dainty, thin stem with a single, small flower at the end. Spring blooms roughly coincide with the first warm rains after the cold winter.
When left undisturbed, these flowers thrive in the wild, and they seed and resprout each season. They’re relatively easy to grow, drought-tolerant, and also come in other colors, like blue, pink, white, and various shades of purple.
Anise Hyssop
Scientific Name: Agastache foeniculum
- Plant Type: Perennial
- Geographic Origin: North America Plains
- Plant Size: Up to 4 feet tall
- Sun Exposure: Part sun to full sun
- Plant Zone: 4-8
If you’ve ever cooked with anise, you might guess that this flower has a faint licorice scent, and you would be right. The flowers are conical, and one plant has a great number of them, attracting butterflies, bumblebees, hummingbirds, and other pollinators in droves. Their flowers range from pale purple to deep indigo, and they thrive in gardens, containers, raised beds, and meadows.
Annual Honesty
Scientific Name: Lunaria Annua
- Plant Type: Perennial
- Geographic Origin: Eastern, Southwestern North America
- Plant Size: 2-3 feet tall
- Sun Exposure: Partial shade to full sun
- Plant Zone: 5-9
The Annual Honesty flower is also known as the Silver Dollar. This plant can grow fairly tall, and its flowers are papery and abundant, making it an easy cut for a floral arrangement. Fragrant purple flowers appear in late spring, and globular moon-shaped fruits appear later in the middle part of summer.
The only potential downside to this flower is that it tends to quickly propagate once it’s sufficiently established in your garden. When left unchecked, it easily verges on becoming a nuisance.
Aster
Scientific Name: Aster
- Plant Type: Perennial
- Geographic Origin: New York and New England, Wild by region
- Plant Size: 1-8 feet tall
- Sun Exposure: Part sun to full sun
- Plant Zone: 3-10
The Aster plant is a daisy-like perennial that is quite attractive to butterflies. The blooms become abundant late in the season, from near the end of summer to early autumn, adding some color as some other plants start to fade. Their late blooms give rise to a nickname: Michaelmas daisies, as their flowers appear near the holiday of the same name in late September.
They have star-shaped flower heads, and depending on the specific cultivar, some asters can grow very tall.
Balloon Flower
Scientific Name: Platycodon grandifloras
- Plant Type: Perennial
- Geographic Origin: Japan, China, the Koreas, Eastern Siberia
- Plant Size: 2-2.5 feet tall

The flower blossoms are between two and four inches wide, with ribbed, tear-drop-shaped petals and a bright yellow center. They often maintain and produce blooms for months and are prized as ornamental plants in gardens and for bouquets. Sometimes, though considered annuals, they will resow on their own.
Geraldton Waxflower
Scientific Name: Chamelaucium uncinatum
- Plant Type: Shrub
- Geographic Origin: Australia
- Plant Size: 4-7 feet tall
- Sun Exposure: Full sun
- Plant Zone: 3-9
This evergreen shrub produces purple flowers and is often referred to as ‘Purple Pride.’ It blooms in late winter, and its small flowers tend to stick around through early spring. It doesn’t require much water, and it will survive in freezing winters, as long as the temperature never drops below about 25 degrees.
Gladiolus
Scientific Name: Gladiolus
- Plant Type: Annual
- Geographic Origin: Europe, Southern Africa
- Plant Size: 2-5 feet tall
- Sun Exposure: Full sun
- Plant Zone: 7-10
Gladiolus are fast-growing and can be quite tall, making them a great choice for small gardens where there is limited horizontal space. The flowers have sword-like petals, leading to their nickname, the sword lily. Vegetable gardeners add gladioli to their gardens to attract pollinators, as the blossoms are quite boldly colored and often purple.
Globe Artichoke
Scientific Name: Cynara cardunculus
- Plant Type: Perennial
- Geographic Origin: Mediterranean
- Plant Size: Up to 6 feet tall
- Sun Exposure: Full sun
- Plant Zone: 7-9
The globe artichoke has purple flowers, but it’s quite attention-grabbing even before it blooms. Young leaves are silvery and become greenish-gray as they grow, with 3-foot lengths being common. Tall flower stalks develop from nodes on the stem, and eventually, the enormous spiky flowers emerge.
Globe artichoke flowers have edible hearts. So, they are harvested before they open. If they are allowed to bloom, they put on quite a display, as huge, purple flowers emerge with hundreds of spiky petals.
Globe Thistles
Scientific Name: Echinops
- Plant Type: Perennial
- Geographic Origin: Parts of Southern Europe, Central Asia
- Plant Size: 2 to 6 feet tall
- Sun Exposure: Full sun
- Plant Zone: 3-9
Globe thistles grow well in shallow, rocky soil and are also tolerant of relatively dry conditions. Their flower heads are perched on the end of long, skinny stems. The flowers are spiky globes with dark blue to purple centers and many prickly whitish spines. They are quite attractive to both the human eyes and certain butterflies.
They can add excellent lift to your garden, and even after their bloom begins to fade, the seed heads add an interesting visual element.
Gloxinia
Scientific Name: Sinningia speciosa
- Plant Type: Perennial bulb
- Geographic Origin: Brazil
- Plant Size: 6 to 12 inches tall
- Sun Exposure: Part shade to full shade
- Plant Zone: 11-12
Gloxinia has exceptionally showy flowers and is often kept as a houseplant. They aren’t very tolerant of the cold, but container plants can be brought outside in warmer months. These are high-maintenance plants, but they’re also reliable seasonal bloomers that may even bloom twice in a year.
Florists’ gloxinia is a term for hybrid varieties that grow these trumpet-shaped flowers in shades of pastel colors, including different hues of purple. These hybrids also have extra-large flowers, with deep cups that have a pattern of varying colors, often fringed with white.
Hardy Geranium
Scientific Name: Geranium bohemicum
- Plant Type: Perennial/Annual/Biennial
- Geographic Origin: Southern Africa
- Plant Size: 1-3 feet tall
- Sun Exposure: Full sun to partial shade

Heliotrope
Scientific Name: Heliotropium
- Plant Type: Perennial
- Geographic Origin: Peru
- Plant Size: 2 feet tall
- Sun Exposure: Full sun to partial shade
- Plant Zone: 10-12
Heliotrope flowers appear in thick clusters and are often shades of purple or violet. They can also be mauve or white. Their leaves are verdant and soft, and the first blossoms appear in the summer after some of the spring bloomers have already slowed down.
The small flowers are clumped so tightly that they appear almost as one, and they hold on into the fall. If you have curious pets or kids, you may want to skip adding heliotrope to your garden, as the plant is highly toxic for humans, dogs, and cats.
Hellebore
Scientific Name: Helleborus
- Plant Type: Perennial
- Geographic Origin: Middle East
- Plant Size: 6 inches – 2 feet tall
- Sun Exposure: Partial shade, more sun in winter
- Plant Zone: 3-9
Hellebores thrive in locations that are well-shaded in summer and much sunnier in the winter. As such, the area under a deciduous tree that loses its sun blocking-rays in the fall is ideal. They bloom very early in the spring or sometimes even in late winter.
Naturally, hellebores come in many colors, but they have been hybridized and can be bought in specific colors, including purple. For instance, the ‘Phillip Ballard’ hellebore has dark blue, purple, and almost black flowers.
Hollyhock
Scientific Name: Alcea
- Plant Type: Annual
- Geographic Origin: Eastern, Southwestern North America
- Plant Size: 3 – 8 feet tall
- Sun Exposure: Full sun
- Plant Zone: 3-8
Hollyhock can grow quite tall, and even the shortest mature plants can be pretty tall. If you plant them from seed, you’ll have to be patient. They won’t bloom the first year, as they are harvesting and storing energy.
The next year, the stored energy will release in the form of dozens of colorful blooms up and down the tall stalks growing from their base of foliage. They spread and self-sow by dropping their seed at the end of each bloom, repeating the process. They do quite well with a bit of support, and some varieties like ‘Creme de Cassis’ are raspberry to purple in color, while others can be pink, rose, red, or even almost black.
Honeywort
Scientific Name: Cerinthe major
- Plant Type: Perennial
- Geographic Origin: Mediterranean
- Plant Size: 2-4 feet tall
- Sun Exposure: Partial shade to full sun
- Plant Zone: 7-10
Honeywort flowers are almost always deep purple, though the shade can vary a bit. The buds grow heavier and heavier as they develop and bloom, eventually getting so heavy that they hang toward the ground. The strong stems remain upright, and the nodding blooms often last from spring through the summer months.
Sometimes, the central flower is wrapped in colorful outer petals or bracts.
Hummelo Betony
Scientific Name: Stachys officinalis ‘Hummelo’
- Plant Type: Perennial
- Geographic Origin: Eastern, Southwestern North America
- Plant Size: 18-24 inches tall
- Sun Exposure: Full sun
- Plant Zone: 4-8
Hummelo is a specific variety of Stachys monieri. Low-growing textured leaves grow in clumps and give rise to long, slender stems. The foliage has a lot of texture, and the tall spiky stems develop conical, spiked, purple flowers in mid-summer. There is some debate about the correct scientific name for this species of betony.
Hyacinth
Scientific Name: Hyacinthus orientalis
- Plant Type: Perennial
- Geographic Origin: Eastern Mediterranean
- Plant Size: 6-8 inches tall
- Sun Exposure: Indirect to full sun
- Plant Zone: 3-9
Hyacinth bulbs require a long period of cool weather each year, or they won’t bloom. So, if you don’t get about thirteen weeks of weather with temperatures between 35 and 48 degrees, you will have to plant hyacinth in containers, making sure to bring them inside into a cold garage or even a refrigerator for the summertime.
They have narrow leaves and thick clusters of blue to purple flowers that explode in color each spring, as long as they have sufficiently cold weather. There are more than 2,000 hyacinth cultivars, including ‘Purple Sensation,’ which is bright purple.
Hydrangea
Scientific Name: Hydrangea macrophylla
- Plant Type: Perennial
- Geographic Origin: Asia, the Americas
- Plant Size: 2-9 feet tall
- Sun Exposure: Full sun with afternoon shade
- Plant Zone: 4-9
Hydrangeas are woody shrubs that have large, ruffled puffy flowers. The exact color of a hydrangea’s flowers depends on the pH of the soil it’s grown in and the exact species you have grown. Typically, the blooms are anywhere from white to pink, red, blue, and purple. Making the soil more acidic or base changes the color from year to year.
They can thrive either indoors or out, depending on the specific variety. The leaves are large and textured. Each flower is a puffy globe made of many small petals. Hydrangeas need pruning each year, or their woody stems can become a bit messy.
Italian Aster
Scientific Name: Aster amellus
- Plant Type: Perennial
- Geographic Origin: Europe
- Plant Size: 8-18 inches tall
- Sun Exposure: Full sun
- Plant Zone: 3-9
Italian aster has small flowers that have a bright orange center and many slender purple petals. They look almost like a cross between echinacea and a white-petaled daisy, and they’re really easy to grow in most home gardens.
Like many other flowering plants, deadheading the spent blooms will increase the likelihood of successive blooms. This relatively small and maintenance-free plant can easily spread, leaving your garden covered in purple flowers. That easy spread is also a potential downside if left unchecked.
Iris Pumila
Scientific Name: Iris Pumila
- Plant Type: Perennial
- Geographic Origin: Eastern, Southwestern North America
- Plant Size: 2-3 feet tall
- Sun Exposure: Part sun to full sun
- Plant Zone: 3-9
The pygmy iris, as Iris Pumila is commonly known, has blades of green foliage and deep purple flowers with a typically light and lacy texture. White and purple flowers are the most common, though some varieties may have blue, white, cream, or varied color patterns. They are perhaps a natural hybrid of Iris pseudopumila and Iris attica.
Lavender
Scientific Name: Lavandula
- Plant Type: Perennial
- Geographic Origin: Europe
- Plant Size: 2-3 feet tall
- Sun Exposure: Full sun
- Plant Zone: 5-9

When the conditions are warm and wet enough, these plants will even bloom year-round. Just keep in mind that they are quite thirsty, requiring up to 12 inches of water per week.
Lily of the Nile
Scientific Name: Agapanthus orientalis
- Plant Type: Perennial
- Geographic Origin: Eastern, Southwestern North America
- Plant Size: 1-4 feet tall
- Sun Exposure: Full sun to partial shade (especially in warm areas)
- Plant Zone: 9-11
Lily of the Nile requires fairly warm conditions, so they won’t grow in areas that see hard winters. They have long stems topped with airy flower heads, formed into puffs of many tiny flowers with curved petals. They are fragile, so the blooms don’t last long, but they’re quite vibrant.
The flower clusters can range from bright shades of purple to blue or white. Their slender stems make them excellent for cutting and placing into tall vases.
Lily Turf
Scientific Name: Liriope muscari
- Plant Type: Perennial
- Geographic Origin: Eastern, Southwestern North America
- Plant Size: 6-12 inches tall
- Sun Exposure: Shade, to part sun to full sun
- Plant Zone: 5-10
Liriope leaves remain verdantly green all year long, so even when they’re not blooming, they add a splash of color to the landscape of your garden. These tough, short plants have strong root networks and can help with erosion control. The grass-like leaves are blade-like, tinged with yellow, and may have stripes.
The flowers range from white to purple and blue, with varying shades in between being common. The sturdy stems develop dense, tight spikes of miniature, bell-shaped flowers, and blooms can occur from spring to fall, depending on the variety.
Lungwort
Scientific Name: Pulmonaria officinalis
- Plant Type: Perennial
- Geographic Origin: Europe and Asia
- Plant Size: Up to ten inches tall
- Sun Exposure: Partial shade to full sun

Lungwort is a relatively short woodland plant that has dainty, small, often purple flowers at the end of slender, woody stems. The plant’s dappled leaves loosely resemble the shape of human lungs, hence the name. The deep bell of the flowers is almost funnel-shaped.
Both the flowers and leaves can have variegated patterns that add to their dramatic presentation. Since they’re usually quite short, they’re commonly used along garden borders.
Lupine
Scientific Name: Lupinus
- Plant Type: Perennial
- Geographic Origin: Mostly North America
- Plant Size: 3-4 feet tall
- Sun Exposure: Full sun to partial shade
- Plant Zone: 4-8
Lupine grows wild, thriving in wide open, breezy meadows. There are many hundreds of species that bloom in various colors, including every shade of purple. The lupine name derives from the Latin word for wolf, owing to a belief that these plants used up much of the nutrients in their soil, almost like a predator.
The tall, conical spire of this wildflower grows quickly, and there are annual and perennial varieties to choose from. Many have purple flowers.
Meadow Sage
Scientific Name: Salvia nemorosa
- Plant Type: Perennial
- Geographic Origin: Europe and Asia
- Plant Size: 1-3 feet tall
- Sun Exposure: Full sun
- Plant Zone: 3-9
This species of Salvia often has purple flowers on top of its spiky racemes. They grow in clumps, and trimming the stems below spent blooms can encourage a second, late-season bloom. They are very attractive to bees and butterflies during their showy blooms. There are many cultivars, so you should make sure to purchase one with your preferred color.
