100+ Beautiful Flowers That Start With B (With Pictures & Names)

Flowers that start with B form one of the largest and most varied groups in the entire alphabet. This guide brings together 100 real flowers, from the delicate Baby’s Breath to the bold Bird of Paradise. Each entry includes a checked botanical name, native range, bloom time, and toxicity note. Whether you garden, arrange bouquets, or just love plant names, this list has something new on nearly every line.

This article is built for several kinds of readers at once. A home gardener can use it to fill a bed with reliable, colorful choices. A florist can use it to find fresh B-letter stems for a bouquet. A parent or pet owner can use it to spot risky plants like Bleeding Heart or Baneberry. A curious plant lover can simply enjoy how wide this one letter’s range turns out to be.

The flowers below are organized in several useful ways. A master alphabetical list comes first, followed by a full comparison table covering all 100 entries. After that come category sections for garden favorites, indoor plants, florist picks, rare finds, and toxic plants, each with real photo captions built in. Color groups and life-cycle groups follow near the end, before a full FAQ section.

Quick Answer: Top Flowers That Start With B

If you only remember a few names, start here. Black-Eyed Susan is a garden classic, prized for cheerful yellow petals and tough, easy care. Bee Balm draws hummingbirds and bees all summer with its shaggy red or pink blooms. Baby’s Breath remains the top filler flower in florist bouquets worldwide. Bird of Paradise brings a bold, tropical shape that few other flowers can match. Bluebell carpets shaded woodlands across Western Europe each spring. Bougainvillea covers walls and fences in vivid papery color through warm months. Balloon Flower earns its name from puffed buds that pop open into star-shaped blooms. Bleeding Heart rounds out the list as a shade-garden favorite, though every part of it is toxic.

Garden Favorites Among Flowers That Start With B

Garden favorites are the flowers gardeners plant season after season without fail. Black-Eyed Susan leads this group, since it blooms for months and tolerates poor soil with ease. Bee Balm draws hummingbirds and bees from the moment its shaggy blooms open each summer. Blanket Flower brings hot red-and-yellow rings to dry, sunny beds with almost no upkeep. Butterfly Bush rounds things out as a shrub that pulls in butterflies from across the yard.

Black-Eyed Susan (Rudbeckia hirta) opens into golden-yellow petals around a dark brown center from midsummer into fall. It self-seeds easily, often returning without any replanting. Image caption: Golden Black-Eyed Susan flowers in a sunny summer border.

Bee Balm (Monarda didyma) sends up shaggy, tubular red or pink flowers that hummingbirds visit constantly. Its crushed leaves release a strong, minty scent similar to bergamot. Image caption: Bright red Bee Balm blooms buzzing with pollinators.

Blanket Flower (Gaillardia aristata) blooms in fiery red-and-yellow rings that keep flowering through summer heat. It handles drought and poor soil better than most border perennials. Image caption: Red and yellow Blanket Flower blooms in a dry garden bed.

Butterfly Bush (Buddleja davidii) grows into a large shrub covered in long, cone-shaped purple flower spikes. Butterflies and bees swarm it from midsummer through the first fall frost. Image caption: Purple Butterfly Bush spikes attracting a monarch butterfly.

Indoor Plants Among Flowers That Start With B

Indoor flowers need to handle lower light and steady room temperatures. Wax Begonia is a strong choice, since its glossy leaves and small blooms thrive in a bright but shaded spot. Bird of Paradise makes a dramatic statement plant, with tropical orange-and-blue blooms shaped like a bird’s crest. Bromeliad adds long-lasting color from a rosette of leaves that needs very little watering. Bletilla, a hardy ground orchid, rounds out the group with a surprisingly easy indoor bloom.

Wax Begonia (Begonia semperflorens) produces small red, pink, or white flowers above glossy, rounded leaves nearly year-round. It tolerates both bright and partly shaded indoor spots well. Image caption: Pink Wax Begonia blooms above glossy green leaves.

Bird of Paradise (Strelitzia reginae) forms a bold, upright plant topped with orange-and-blue crane-shaped flowers. It needs a large pot and several years to reach flowering size indoors. Image caption: Orange and blue Bird of Paradise flower in a bright room.

Bromeliad (Guzmania lingulata) holds a bright red or orange flower spike at its center for weeks at a time. It needs very little soil, since it draws much of its water through its leaves. Image caption: Red Bromeliad flower spike on a windowsill.

• Wax Begonia — glossy leaves, small blooms nearly year-round
• Bird of Paradise — dramatic tropical statement plant
• Bromeliad — long-lasting color, low watering needs
• Bush Violet — soft blue-purple blooms for a shaded room
• Bletilla — surprisingly hardy ground orchid for a bright pot

Bird of Paradise and Bletilla both reward patience, since neither blooms quickly from a young plant. Wax Begonia and Bush Violet are far more forgiving, flowering within weeks of planting. Bromeliad remains the lowest-maintenance of the group, tolerating real neglect between waterings.

Florist Favorites Among Flowers That Start With B

Florists choose flowers for strong stems, long vase life, and dependable color. Baby’s Breath is the most widely used filler flower in the entire cut-flower industry. Balloon Flower adds an unusual puffed bud stage that opens into a star-shaped bloom in the vase. Bouvardia offers clustered white or pink blooms often used in wedding bouquets. Barberton Daisy, better known as Gerbera Daisy, brings some of the boldest, cleanest color of any cut flower.

Baby’s Breath (Gypsophila paniculata) produces a cloud of tiny white flowers on thin, branching stems. Florists use it to soften and fill space around larger focal blooms. Image caption: A cloud of tiny white Baby’s Breath flowers.

Bouvardia (Bouvardia longiflora) grows in clusters of small, star-shaped, fragrant white or pink flowers. It remains a popular choice for bridal bouquets due to its soft color and scent. Image caption: Clustered white Bouvardia flowers in a bridal bouquet.

Barberton Daisy (Gerbera jamesonii) opens into large, flat blooms in nearly every bright color available. Its long, sturdy stems make it one of the easiest daisies to arrange. Image caption: Bold orange Barberton Daisy flower in a vase.

• Baby’s Breath — classic filler flower for nearly any bouquet
• Balloon Flower — puffed buds that open into star shapes
• Bouvardia — fragrant clusters favored for weddings
• Barberton Daisy — bold, flat blooms in bright colors
• Bells of Ireland — unusual green bell-shaped spikes for texture

Baby’s Breath and Bells of Ireland both work as supporting players, adding texture rather than a focal point. Bouvardia and Barberton Daisy instead take center stage in most arrangements. Balloon Flower sits between the two, useful both as an accent and a quiet focal bloom.

Rare Flowers That Start With B

A handful of B-flowers rarely show up outside specialist growers or native plant sales. Himalayan Blue Poppy is famous among gardeners for its true-blue color and its reputation as difficult to grow outside cool, damp climates. Baboon Flower is a South African bulb sold mostly through specialty catalogs, prized for unusual purple-blue blooms. Blue Throatwort remains uncommon in home gardens despite its cloud of small, star-shaped purple flowers. Bergenia is easy to overlook until its pink spring blooms rise above thick, leathery leaves.

Himalayan Blue Poppy (Meconopsis betonicifolia) produces papery, true-blue petals around a golden center in early summer. It needs cool, moist, acidic soil that is hard to replicate outside its native range. Image caption: Rare true-blue Himalayan Blue Poppy in bloom.

Baboon Flower (Babiana stricta) sends up short spikes of purple, blue, or red flowers from a small South African bulb. Its common name comes from baboons that were once seen digging up the corms to eat. Image caption: Purple Baboon Flower blooms in a spring bulb bed.

Bergenia (Bergenia crassifolia) holds thick, leathery leaves year-round and pink flower clusters each spring. It tolerates cold winters better than most other flowering ground covers. Image caption: Pink Bergenia flower clusters above leathery leaves.

• Himalayan Blue Poppy — famously difficult true-blue bloom
• Baboon Flower — rare South African bulb, unusual color
• Blue Throatwort — uncommon cloud of small purple stars
• Bomarea — climbing Andean relative of Peruvian Lily
• Bracted Honeysuckle — rare native shrub with dark berries

Himalayan Blue Poppy and Baboon Flower both demand very specific growing conditions that most home gardens cannot easily provide. Blue Throatwort and Bomarea instead simply remain hard to find, rather than hard to grow. Bergenia is the most forgiving of the group, tolerating neglect far better than its rarity would suggest.

Flowers That Start With B and Need Caution

A meaningful group of B-flowers carries real toxicity risk, especially around kids and pets. Baneberry produces bright, eye-catching berries that are highly toxic if eaten in any amount. 

Bleeding Heart contains toxic alkaloids throughout the plant, most concentrated in the roots. Bluebell bulbs closely resemble edible alliums but carry real cardiac-affecting toxins instead. Bloodroot gets its name from a red sap that is toxic and can irritate skin on contact.

Baneberry (Actaea rubra) produces small white spring flowers followed by shiny red or white berries in summer. Every part of the plant, especially the berries, is highly toxic if eaten. Image caption: Bright red Baneberry berries on a woodland stem.

Bleeding Heart (Lamprocapnos spectabilis) forms rows of heart-shaped pink or white flowers along an arching stem each spring. The entire plant, especially the roots, is toxic if ingested. Image caption: Pink heart-shaped Bleeding Heart flowers on an arching stem.

Bluebell (Hyacinthoides non-scripta) carpets shaded woodlands with nodding, fragrant blue flowers each spring. Its bulb closely resembles an edible onion but is toxic if eaten. Image caption: Carpet of blue Bluebell flowers in a spring woodland.

• Baneberry — highly toxic berries; keep children and pets away
• Bleeding Heart — toxic alkaloids throughout, most concentrated in roots
• Bluebell — toxic bulb resembling edible alliums
• Bloodroot — toxic red sap, irritates skin on contact
• Bittersweet Nightshade — toxic berries, common in hedgerows
• Bog Rosemary — toxic nectar and foliage, grayanotoxin risk

Baneberry deserves the most caution here, since even a few berries can cause serious illness. Bleeding Heart and Bluebell both look harmless enough to tempt curious children or pets. Even so, all six of these are best kept out of reach in homes with toddlers or grazing animals nearby.

Color-Based Groupings of Flowers That Start With B

Grouping flowers by color helps with planning a themed bed or bouquet. Blue and purple tones dominate this letter more than almost any other. Bluebell, Bachelor’s Button, Blue Star, and Himalayan Blue Poppy all bring cool blue-purple shades that pair beautifully in a calm, layered border.

Yellow and gold flowers bring warmth and stand out from a distance. Black-Eyed Susan, Butter Daisy, and Blanket Flower all lean into bright gold and yellow tones, making them easy to spot from across a garden. These work well near a patio, where bold color reads clearly from a seated view.

Pink and red flowers suit romantic or high-energy garden themes equally well. Bee Balm and Blood Flower both bring fiery red tones that draw hummingbirds from a distance. Bleeding Heart softens that energy with a gentler pink, and Barberton Daisy adds a bold, flat red bloom nearby.

White flowers add calm, quiet contrast to any of the groups above. Baby’s Breath, Bells of Ireland, and Bird’s Eye Primrose all bring soft white or cream tones to a bed or bouquet. Bouvardia adds fragrance to this group, making it a favorite choice near patios and entryways.

Life-Cycle Groupings of Flowers That Start With B

Knowing a flower’s life cycle helps you plan how often to replant a bed. Annuals complete their life cycle in a single season, so they need fresh seeds or plants each year. Perennials return from the same roots for years, while bulbs store energy underground between bloom cycles. Shrubs and woody vines take the longest to establish but reward patience with repeat yearly blooms.

Life Cycle Type	Example Flowers
Annual	Bachelor’s Button, Baby Blue Eyes, Bells of Ireland, Basket Flower
Perennial	Black-Eyed Susan, Bee Balm, Blazing Star, Bergenia
Bulb	Bluebell, Baboon Flower, Bomarea, Byzantine Gladiolus
Shrub or Woody	Butterfly Bush, Bougainvillea, Beauty Bush, Bristly Locust

Annuals like Bachelor’s Button and Basket Flower reward gardeners who enjoy fresh planting each spring. Bulb types such as Bluebell and Bomarea need a period of dormancy to bloom each year reliably. Shrubs and woody plants take the longest of all four groups to reach a full, established size.

Botanical Name Crosswalk for Flowers That Start With B

Botanical names matter more than most gardeners expect. Common names shift by region, but a botanical name stays fixed everywhere in the world. This matters most when ordering online, since the wrong common name can return a completely different plant. The crosswalk below pairs common names with correct botanical names and plant families for accurate, confident searching.

Common Name	Botanical Name	Plant Family
Baby’s Breath	Gypsophila paniculata	Caryophyllaceae
Black-Eyed Susan	Rudbeckia hirta	Asteraceae
Bee Balm	Monarda didyma	Lamiaceae
Bleeding Heart	Lamprocapnos spectabilis	Papaveraceae
Bluebell	Hyacinthoides non-scripta	Asparagaceae
Bird of Paradise	Strelitzia reginae	Strelitziaceae
Bougainvillea	Bougainvillea glabra	Nyctaginaceae
Butterfly Weed	Asclepias tuberosa	Apocynaceae
Baneberry	Actaea rubra	Ranunculaceae
Bloodroot	Sanguinaria canadensis	Papaveraceae
Baby Blue Eyes	Nemophila menziesii	Boraginaceae
Bluebonnet	Lupinus texensis	Fabaceae
Barberton Daisy	Gerbera jamesonii	Asteraceae

This shortlist shows how varied the plant families really are, even within one letter. Bleeding Heart and Bloodroot both sit in the same poppy family, which explains their shared toxicity pattern. Bluebonnet stands apart in the pea family, connecting it to other toxic legumes despite its cheerful spring color.

Flower Meanings and Symbolism

Flowers that start with B carry rich symbolism across many cultures. Bee Balm has long been linked to healing and comfort, since Indigenous communities in North America used it in traditional remedies. Its bright red color also draws a strong link to energy and attraction, fitting for a flower that hummingbirds cannot resist. Black-Eyed Susan, by contrast, is often tied to encouragement and justice, sometimes given as a message of support during hard times.

Bluebell holds a gentler, more wistful meaning across British and Irish folklore. Old stories warned that walking through a bluebell wood could lead someone astray, giving the flower a quiet, mysterious reputation. Baby’s Breath, on the other hand, symbolizes everlasting love and purity, which is exactly why it appears in so many wedding bouquets around the world.

Bleeding Heart carries perhaps the most literal symbolism of any flower on this list. Its heart-shaped blooms are widely read as a symbol of love, loss, or emotional vulnerability. That contrast between beauty and real toxicity gives Bleeding Heart a symbolism that feels earned rather than simply decorative.

Decision Guide: Which Flower That Starts With B Should You Choose?

Choosing the right flower often depends on where it will grow and who will be near it. The table below matches common situations to a flower pick from this list, along with a short reason for the match. Use it as a starting point, then check the full comparison table above for growing details.

Your Situation	Recommended Flower	Why It Fits
Sunny summer border	Black-Eyed Susan	Tough, reliable, long bloom time
Hot, dry rock garden	Blanket Flower	Drought-tough with fiery color
Indoor bright room	Wax Begonia	Blooms nearly year-round indoors
Fragrant cut flowers	Bouvardia	Sweet scent, wedding-ready blooms
Native pollinator bed	Bee Balm	Feeds hummingbirds and bees all summer
Household with pets	Black-Eyed Susan	Non-toxic and easy to grow
Shaded woodland bed	Bluebell	Naturalizes well in shade, but toxic if eaten
Fence or trellis cover	Bougainvillea	Fast-growing, vivid warm-climate color

Notice that Black-Eyed Susan appears twice in this table, once for sunny borders and once for pet-safe homes. That overlap is not an accident, since the same traits that make it easy to grow also make it low-risk indoors and out. Bluebell, by contrast, is stunning in a shaded bed but needs careful placement, since it appears again in the caution section above.
