Whether you're planning a garden, picking out wedding bouquets, or helping a kid with a school project about plants, a sorted list of flowers makes things easier. The 50 flowers below cover garden classics, wildflowers, tropical blooms, and flowering shrubs - all arranged A through Z. From the showy dahlia to the delicate forget-me-not, these are the varieties you'll find most often at nurseries, florists, and growing in gardens around the world.
Need to sort your own flower list? Maybe you're organizing inventory for a garden center, building a planting schedule, or creating labels for a botanical display. Paste your list into the tool above and it'll alphabetize everything instantly. Works with any number of items, no sign-up required.
How Many Flower Species Exist?
Botanists estimate there are roughly 400,000 known species of flowering plants (angiosperms) on Earth. That number keeps climbing as researchers discover new species in remote rainforests, mountain ranges, and even backyards. The 50 on this page are among the most widely cultivated and recognized - the ones you'd find at a typical garden center or in a florist's cooler.
Some entries on this list are actually genera containing hundreds or even thousands of species. "Orchid" alone covers about 28,000 species, making Orchidaceae one of the two largest families of flowering plants. Roses include over 300 species and tens of thousands of cultivated varieties. So when we say "50 flowers," we're really covering an enormous range of botanical diversity under familiar names.
Flowers by Bloom Season
Timing matters in a garden. Spring leads off with crocuses and daffodils pushing through the last of winter's cold, followed by tulips, bluebells, lilacs, peonies, and magnolias. It's the biggest show of the year for bulb flowers. Summer brings the heavy hitters - roses, sunflowers, lilies, lavender, dahlias, hibiscus, and hydrangeas fill gardens with color from June through August. Fall slows things down but doesn't stop entirely - chrysanthemums, asters, marigolds, and some dahlias keep blooming until the first frost.
A handful of flowers bloom year-round in the right conditions. Carnations are available from florists every month of the year because commercial growers produce them in climate-controlled greenhouses. Orchids, bird of paradise, and geraniums (in mild climates) also provide continuous color. If you're planning a garden that includes fruit trees, pairing bloom seasons between flowers and fruit blossoms creates a pollinator-friendly landscape that stays active from early spring through fall.
Flower Families Worth Knowing
The Asteraceae family (daisy family) dominates this list with asters, black-eyed Susans, chrysanthemums, dahlias, daisies, marigolds, sunflowers, yarrow, and zinnias. These composite flowers share a distinctive structure - what looks like a single bloom is actually dozens or hundreds of tiny flowers (florets) packed together on a single head. That's why sunflower "seeds" form in spiral patterns across the face of the flower.
The Ranunculaceae family (buttercup family) contributes anemones, buttercups, clematis, delphiniums, and ranunculus. Many members of this family contain alkaloids that make them mildly to seriously toxic - so they're beautiful to look at but not great choices if you have pets that chew on plants. The Iridaceae family gives us irises, crocuses, and freesias, all growing from bulbs or corms and putting on their show mostly in spring.
Roses stand alone in the Rosaceae family on this list, though that family also includes many fruit-bearing plants like apples, strawberries, and cherries. The connection isn't coincidental - both roses and fruit trees produce flowers that attract pollinators, and the rose hip (the fruit of a rose) is edible and packed with vitamin C.
