Let’s look at 59 types of blue flowers available for you to consider when choosing a plant for your garden or floral arrangement.
1. Hydrangea
Hydrangeas are large, beautiful flowers that do best in USDA hardiness zones 3 to 9.
These flowers are unique in that you can get blue blooms depending on the pH of the soil – acidic soil under pH 5.5 produces blue flowers, depending on the hydrangea species.
Hydrangeas bloom in the summer and fall. Its sunlight needs vary depending on the hardiness zones and species, and it may require anything from full sun to full shade. Blue hydrangeas symbolize apology, gratitude, and understanding.
2. Cornflower
Also known as the bachelor’s button, the cornflower is a plant native to Europe. This flower does best in USDA hardiness zones 2 to 11 and requires full sun to partial shade to grow and flower properly.
These annual flowers bloom in the spring and summer for about ten weeks. If you decide to deadhead them, you can increase their bloom time for a few weeks.
These wildflowers are a good option to plant if you want to attract bees and butterflies to your garden. Additionally, they make popular cut flowers due to the brightly colored blooms, with blue being a particularly popular color.
3. Dwarf Morning Glory
Native to South America, the dwarf morning glory is also known as blue daze. This flower is an excellent choice if you’re looking for types of blue flowers that provide ground cover for your garden.
A perennial plant, the dwarf morning glory grows best in USDA hardiness zones 8 to 11. However, you can also grow the dwarf morning glory as an annual in cooler zones.
This member of the morning glory family is a great option if you plan on attracting pollinators like butterflies and bees. The flowers always bloom blue, making this an excellent choice if you’re looking for a true-blue flower.
It should be planted in the spring and requires full sun to grow well. If the conditions are right, this plant will take only a few weeks to grow fully.
4. Iris
The iris is among the best-known and most popular among the different types of blue flowers worldwide. It is named after the Greek goddess of the rainbow and is available in various hues and shades – including blue.
These gorgeous flowers do best in USDA hardiness zones 3 to 9 and require full sun to partial shade, depending on the temperature and the hardiness zone. Iris flowers are used around the world and are considered to be purifying in Japan.

An easy-to-grow plant, the lobelia is easy to care for and doesn’t require deadheading. It has been prized for its medicinal uses for centuries. However, if you’re growing lobelia for medicinal purposes, it’s essential to be careful – in high doses, it is toxic to animals and humans.

Additionally, their flowers are available in several colors, including blue, allowing homeowners to add a bright splash of color to their houses without demanding too much space.

8. Blue Hibiscus
Despite its name, the blue hibiscus isn’t actually a Hibiscus.
Though the plants look similar, the blue hibiscus is actually related to mallow plants. These fast-growing plants do best in USDA hardiness zones 9 to 11.
The other thing to remember with the blue hibiscus is that this plant isn’t a true-blue plant – that is to say, the flowers aren’t actually pure blue.

This plant is relatively easy to grow and care for, though it does require some pruning. These plants are native to Australia.
9. Balloon Flower
Also known as platycodon, the balloon flower is named for the balloon-shaped buds of this flower before it blooms. This plant is native to Asia and Russia and does best in USDA hardiness zones 3 to 8.
