Annual Flowers that Start with G

Gaillardia (Gaillardia x Grandiflora)

Gaillardia is part of the daisy family, Asteraceae which is native to the Americas. While botanists consider this a short-lived perennial, many gardeners grow it as an annual. It thrives in full sun and grows to be just over a foot tall. It blankets the ground in brilliant color, hence the name!

Gardenia (Gardenia jasminoides)

The gardenia is one of the most iconic flowers that start with G. It’s a shrub that blooms with fragrant white rose-like flowers. This hard-to-grow shrub can grow outdoors, but only in ideal conditions. It’s considered an annual in most zones. Most gardeners prefer to grow them indoors because they are native to tropical regions.

Geranium (Pelargonium spp.)

This flower is not truly a geranium, rather it’s a pelargonium! It was erroneously dubbed “geranium” because the flowers bore a resemblance to wild geranium.

Pelargoniums are native to south Africa and can be grown in part sun or part shade. To keep the flower alive year-round, overwinter it indoors or take cuttings to regrow in spring. 

Gerbera daisy (Gerbera jamesonii)

Also native to South Africa, the Gerbera daisy can be grown indoors or outdoors as an annual. Florists like them for their bold colors and long-lasting flowers. They grow well in sunny spots indoors or in part shade outdoors. But be careful not to overwater, this flower is prone to root rot.

Globe Amaranth (Gomphrena globosa)

This tropical native from central America blooms all summer. It shows off sprays of pink, red, purple, and white globe-like flowers. The beautiful colors are from the bracts, not the flowers. It grows up to two feet tall and makes a colorful addition to any garden.

Gloxinia (Sinningia speciosa)

Also known as the African violet, gloxinia is usually grown as an indoor plant. This plant has velvety, vibrant flowers and it needs a dormancy period to rebloom. It’s a notoriously sensitive plant that hates cold water on its leaves.

Gypsophilia spp. (Baby’s Breath)

Some species of baby’s breath are perennial in Zones three to nine. However, most varieties are annuals. The plant’s multitude of white or pink flowers grow in mounds and is native to Europe and Asia. Some states classify baby’s breath as an invasive weed, so plant with caution!

Gas plant (Dictamnus albus)

A native to Europe, the gas plant has white, spidery flowers. It’s a herbaceous perennial that grows in Zones three to nine. When its seedpods dry in hot weather, they will emit a gas that’s flammable. That’s where it gets the name!

Gaura lindheimeri (Wand flower)

Germander (Teucrium spp.)

The germander is part of the mint family and is native to the Mediterranean. This shrub can reach towering heights of 8 feet. It’s drought-tolerant and does well in rocky or sandy soils. In Zones five to nine, it will return year after year. This is one of the tinier and delicate flowers that begin with G.

With proper care, it can bloom from spring through the end of summer. To remain vigorous, Geum needs to be divided yearly.

Giant barrel cactus (Echinocactus platyacanthus)

The rare globeflower stands out from the crowd with yellow and orange flowers. While it’s native to northern Europe, it can thrive in U.S. Zones three to eight. It does best in somewhat damp conditions and prefers cooler climates. It’s often found in meadows and swamps.

Globe thistle (Echinops spp.)

The globe thistle is a Dr. Seuss-like perennial from the Mediterranean. It will grow in Zones two to eight in full sun and free-draining soil. Its blue, spikey globe flowers seed freely after blooming. Some varieties can grow to be four feet tall.

Goatsbeard (Aruncus spp.)

It’s no surprise where this flower got its name! Its white, spiky blossoms resemble a goat’s beard. It grows in Zones three to eight and is native to North America. While it’s only in bloom for 10 days, it makes for a lovely cut flower, making it one of the special flowers that start with G.

Godetia (Clarkia amoena)

This fast-growing plant grows up to two feet tall and can be planted in Zones three to eleven. The godetia is one of the most beautiful prairie wildflowers native to North America. It grows best in full sun to partial shade.

The golden groundsel is mostly grown as a ground cover. It does especially well in wetter parts of the garden or in moist soils. Another U.S. plant, the golden groundsel is native to eastern North America. It spreads by rhizome, so if you plant it, make sure it doesn’t take over!

Goldenrod (Solidago spp.)

This quintessential North American native has over one hundred species. It’s easily propagated by rhizome or self-seeding. It’s both deer-resistant and pollinator friendly. Best of all, it has clusters of yellow flowers that look like bursting fireworks.

While the gooseneck loosestrife is a showy architectural plant, it is invasive in North America. This native to China and Japan is a fast-growing perennial that spreads by rhizome. It’s typically grown for flower arranging. Its tall white flowers resemble goosenecks, hence the name.

Grape hyacinth (Muscari armeniacum)

The bright purple blooms of the grape hyacinth arrive in spring. It is not actually from the hyacinth family, but is a bulb from the asparagus family. They’re native to Asia and perennial in Zones four to eight. As their name indicates, their bright purple flowers resemble tiny grapes.

Gumamela (Hibiscus rosa-sinensis)
