The world of flowers that start with H is vibrant, colorful, and full of surprises! Familiar blooms like hibiscus, hyacinth, and honeysuckle, each belonging to a distinct genus of plants, are just some of the H varieties that will brighten your garden and expand your flower knowledge. In this list, you’re sure to find several that will suit your taste and your landscape.

Gorgeous Flowers That Start With H
1. Hibiscus (Hibiscus rosa-sinensis)
Chinese hibiscus, a perennial species from the mallow family, also goes by the name of these flowers. They are well-known for their large, funnel-shaped flowers, which come in a wide range of colors, including red, pink, yellow, orange, and white.
Gardeners grow hibiscus as a houseplant that thrives in warm temperatures and blooms during spring and early summer when sunlight increases.
2. Hellebore (Helleborus spp.)
Other names of hellebore include helleborus, Christmas rose, or lenten rose. These flowers are native to Asia, Morocco, and Europe, and feature cup-shaped flowers in shades of white, purple, yellow, red, and pink.
They thrive in areas with well-drained soils and receive light to moderate shade.
3. Honeysuckle (Lonicera spp.)
People love honeysuckles for their sweet fragrance and tubular or trumpet-shaped flowers that attract all types of pollinators, especially bees and butterflies.
You can plant them as fast-growing vines to cover fences and walls, and they can easily find a spot in your garden if you enjoy their scent.
Just be aware: some species, like the Japanese honeysuckle, may invade and take over other plants.
4. Helenium (Helenium autumnale)
These golden blooms with velvet-textured petals are also called Helen’s flower and sneezeweed. Helenium is a perennial plant native to many regions in the United States and Canada.
Yellow flowers are abundant in the wild, but some hybrids have been cultivated to suit ornamental gardens that come in other shades like orange, red, gold, and even brown. They’re at their best under a full sun in fertile, moist soils.

5. Helichrysum (Helichrysum bracteatum)
Helichrysum is commonly referred to as Golden Everlasting, Immortelle, Paper Daisy, and Everlasting Flower. It gets these monikers because it retains its gorgeous colors even when dried, extending its lifespan almost indefinitely when used in floral arrangements.
Like daisies, helichrysum features a central yellow disk, with petals available in yellow, white, pink, or orange colors. It blooms from late spring to early winter.
6. Heliotrope (Heliotropium arborescens)
Native to Peru, heliotrope is cultivated as a summer bedding plant, a houseplant, or a border plant in many areas. They form clusters of tiny bright blue, purple, or white flowers that give off a tender, vanilla-like scent.
All parts of the heliotrope are poisonous, but they can only be toxic to humans if consumed in large amounts.
7. Hyacinth (Hyacinthus orientalis)
Hyacinth may just be one of the most beloved fragrant flowers that start with H, thanks to its natural beauty. It’s a spring-flowering bulb native to eastern Mediterranean areas like Lebanon, Syria, and Turkey, but it quickly gained popularity in Europe after it was introduced there.
Hyacinths have spikes that produce bell-shaped flowers in white, orange, yellow, blue, or lavender colors. It can bloom anytime from March to May.
8. Hydrangea (Hydrangea macrophylla)
Also called Hortensia or Snowball Plant, hydrangeas are native to Asia, particularly Japan, China, and Korea. Some refer to them as “mop-head” hydrangeas since they produce mop-head clusters of small ball-shaped blooms.
They grow best in areas with deep or partial shade and good drainage. Interestingly, the color of the flowers depends on the soil pH or acidity. Blue hydrangeas emerge from acidic soil, while pink flowers bloom from areas with alkaline soil.

9. Heather (Calluna vulgaris)
Calluna vulgaris, also known as Scotch Heather, is a low-growing plant that is best used as a ground cover. It originated from Europe and can be an iconic sight once groups of it blanket the moorlands and heaths.
The feathery flowers often come in shades of pink or light violet, but some white varieties also exist. Its nectar is a valuable food source for insects like bumblebees and butterflies.
10. Hesperis (Hesperis matronalis)
Also called Dame's Rocket, Hesperis is a biennial plant characterized by its showy, scented flowers in white, pink, or purple colors. It’s very fragrant and easily grows in areas with well-drained soil and full sun to part shade.
Hesperis is an excellent flower for cottage gardens or meadows. Just note that some areas outside of Missouri list it as a noxious weed that should not be grown where it can disseminate.
11. Heuchera (Heuchera spp.)
Heuchera or Coral Bells are versatile perennials with tiny bell-shaped white or pink flowers. However, they are also prized for their colorful foliage that ranges from deep purple to lime green.
Heuchera is easy to grow as it blooms in various conditions, such as full sun, full shade, rich soil, clay, salt, etc. Once established, this plant may be drought-tolerant. Plant them in pots or shade gardens to enjoy their beauty.
12. Hepatica (Hepatica nobilis)
This charming woodland flower is also called Liverleaf, Ivy Flower, and Liver Moss. It features dainty blue or purple flowers with white stamens that bloom during early spring.
Hepatica can be a beautiful addition to city or rock gardens, borders, or planted in containers en masse to maximize its visual appeal.

13. Houttuynia (Houttuynia cordata)
The Chameleon Plant and Rainbow Plant are the common names by which Houttuynia is known. This groundcover from Asia features showy leaves with unusual fall colors and small white flowers, accompanied by a green spike in the center.
It grows best under full sun but can tolerate shade. The leaves and stems have some medicinal uses, particularly in China, where they’re used against health issues such as fever, cough, and pneumonia.
14. Hardenbergia (Hardenbergia violacea)
This plant originates from South Australia and is also known by the names Coral Pea, False Sarsaparilla, Happy Wanderer, and Vine Lilac. It has purple flowers that bloom from late winter to early spring, providing color and attracting pollinators in a time when little else is flowering.
Hardenbergia is excellent to use on fences and trellises.
15. Hoya (Hoya carnosa)
Garden enthusiasts know Hoya—often called the Honey Plant or Wax Plant—for its thick green leaves and the waxy texture of its star-shaped flowers. These blooms are typically pink or white with red centers and would emit a sweet smell.
Hoya grows as a vining evergreen that clings to trees or rocks outdoors, and gardeners often grow it in hanging baskets or pots indoors.

16. Hedychium (Hedychium coronarium)
Our last entry for flowers that start with H is the Hedychium, which is also called Ginger Lily or White Garland Lily. This tropical plant has large, striking white flowers that emit a luxurious fragrance, but they only last a day.
Hundreds of them can appear when they bloom from late summer to early fall. These flowers are perfect for Mediterranean gardens, containers, beds, and borders.
