How many flowers that start with G do you already know about? Two, three?
I know it can be challenging to come up with, say, five flowers that fit into this description. What’s even more frustrating is that many of us don’t remember what a lot of flowers look like, except maybe for tulips, roses, and daisies!
Now, it turns out that countless flowers start with the letter G. For instance, you’ve got Geraniums, Gardenias, Great Periwinkles, Garden Stocks, Gladiolus, and the list goes on. I review some of these flowers in some detail below.
If you’re curious to learn the secret lives of each one of those flowers that start with G, I’d be glad to help. In this article, I’ll be exploring the different features of eight blooms, so are you prepared to be blown away by their charm?
1. Geranium
You’ve probably heard of Geraniums since they’re popular flowers that start with G. But, just like me, you may not have had an idea if they’re big or small, what colors they come in, or how to take care of them. Let me enlighten you!
Geraniums are the top choices for many gardening lovers because they have vibrant colors that you can’t help but feel a little bit more cheerful when you spot them. These showy blooms come in shades of orange, purple, pink, red, white, and salmon, but you can also find bicolored varieties.
Better still, Geraniums adjust to all types of climates pretty fast. As long as you provide yours with direct sunlight and rich, medium-moisture soil, you should be covered!
However, one important fact you should keep in mind about this pretty flower is that it’s toxic to humans and animals. So, if you’re planning to plant it indoors or outdoors, ensure it’s not accessible by your pets or kids.
Other names of Geranium flowers include:
- Pelargonium (botanical name)
- Regal Geranium
- Annual Geranium
- Ivy-leaved Geranium
2. Gardenia
Gardenias are another flower species that are quite famous. Once you take a look at them, you’ll see why people from all over the world like them so much.

These flowers are tiny, delicate things with white petals and a wonderful fragrance that greets you as soon as you enter the garden. Talk about unrivaled feelings of coziness!
Gardenias prefer full sunlight and a warm, humid climate. They’re not exactly fans of dry soil, so you must be careful to keep the soil just moist enough to their liking without flooding it with water. If you do, it’ll end up being the perfect breeding ground for parasites and harmful microorganisms.
Just like Geraniums, Gardenias are known by other monikers besides this more popular one, and these are:
- Gardenia jasminoides (botanical name)
- Cape jasmine
3. Great Periwinkle
Want to add a lavender touch to your backyard flower garden? Well, I might just have the right flower for your needs; the Great Periwinkle is at your service!
This lovely bloom has pretty petals that form the shape of a star. These petals come in pale blue-lavender hues with white centers that create an eye-catching contrast.
Great Periwinkles are also pretty easy to grow because they’re widespread over the Northern Hemisphere. Therefore, no matter where you live in the United States, the weather should be suitable to maintain the well-being of these flowers.
Still, if you leave them without supervision for a long while, they can become invasive. So, you’d better watch out for the sake of the rest of your flowers!
Besides their rather expressive name, Great Periwinkles are also called:
- Vinca major (botanical name)
- Blue Periwinkle
- Bigleaf Periwinkle
- Large Periwinkle
4. Garden Stock
Garden Stock plants produce cute clusters of flowers that you can find in shades of pink, purple, red, or white. Yet, their pretty colors aren’t the only special features of these flowers because they’re well-known for their lovely perfume.
Because Garden Stocks are native to England, they prefer cool weather. As a result, your best bet is to grow them in the spring or the beginning of summer when the temperatures aren’t too high.

Again, their original habitat dictates that you plant Garden Stocks in partial sunlight since direct sun rays can be too harsh on them. Plus, you’ll need to offer them moist, well-draining soil to ensure they grow into happy and healthy blooms.
Garden Stocks have other names, too, such as:
- Matthiola incana (botanical name)
- Ten-weeks
- Gilly flower
- Hoary
5. Gladiolus
Want to introduce some bulb-shaped flowers to your garden that aren’t tulips? It’s time for you to consider going for Gladiolus flowers with their numerous color varieties, pretty ruffles, and tall stems.
Gladiolus flowers call South Africa their home, so it’s not surprising for them to demand full sunlight and soil that drains fast. Because of their immense hardiness, they can withstand drought periods. They’ll also handle a bit of shade, but not for too long.
More interestingly, Gladiolus flowers are winter-hardy to an extent, which I honestly didn’t expect out of an African-native flower. If you live in zones eight to ten, you’ll have to dig these flowers up in the fall and replant them in the spring to maintain their glory.
It’s also worth mentioning that Gladiolus flowers are toxic to humans and animals if ingested.
Thinking about the other names Gladiolus flowers have? Here you go:
- Gladiolus palustris (botanical name)
- Gladiola
6. Grape Hyacinth
Grape Hyacinths are uniquely shaped blooms that are sure to draw the attention of every visitor you invite on a tour of your garden. As the name suggests, these flowers appear in grape-shaped blue or purple blooms, and they make for an awesome groundcover.
You can come across Grape Hyacinths in other color variations, too, such as yellow and white.
Native to southeastern Europe, these flowers have special requirements if you want to grow them at home, but, thankfully, they’re low-maintenance. They only need full sun to partial shade, so you can keep them outdoors or indoors right next to a window.
In addition to that, Grape Hyacinths demand well-draining soil that doesn’t house other plants that could hag all the nutrients inside it. They also require humid surroundings; if you grow them indoors, make sure to mist them lightly every now and then.
Besides their interesting name, Grape Hyacinths also go by:
- Muscari armeniacum
- Bluebells
- Muscari
7. Globeflower
Slightly round like, you guessed it, a globe, the Globeflower is a must-have for people who admire unusual flower shapes and bright yellow color splashes in their gardens.

The Globeflower is European, and it likes its moisture to be pretty high. In its homeland, you can find it spread on the edges of ponds or water gardens, in bogs or ditches, or even in rain gardens.
Therefore, if you wish to recreate its natural habitat wherever you live, always make sure the soil you’re using is wet.
As for sunlight needs, keep in mind that different Globeflower versions require various levels of sun exposure. So, you should do some research on the specific species of Globeflower that you have to know how it likes its sun.
The Globeflower has several names you can refer to it by, including:
- Trollius
- Trollius europaeus
8. Gumamela
You may know the Gumamela flower by its other, more common name, which is the hibiscus. This pretty flower is famous for its large red petals and broad leaves. However, it’s also available in shades of pink and white based on the variety.
More interestingly, the Gumamela genus involves hundreds of species, so it’s not surprising to find peach, orange, and yellow flowers, too. These flowers are found in the tropical regions of the world, so they prefer their weather to be warm and inviting.
Ready to prepare a nice spot for this cute flower in your garden? Easy.
Hibiscus flowers are best kept in indoor containers during the summer and fall, where you can have better control of the temperature and humidity levels. You’ll also need to provide them with moist soil that drains well and full sunlight to partial shade.
Since the Gumamela flowers come in more than 300 varieties, you’re right to assume they have a wealth of names that people have given them over the years. These names include:
- Hibiscus rosa-sinensis (botanical name)
- China rose
- Chinese hibiscus
- Rose mallow
