Blue lobelia is an Annual with Sky-Blue Blossoms

It grows in groups about a foot wide. It can be planted in flowerbeds as a border or ground cover, or in pots and window boxes, where it will cascade over the sides. It's especially attractive in a hanging basket, where it will trail down. Blue lobelia can grow in zones 2 to 11 and produces an abundance of bright blue flowers. It's sometimes thought that blue lobelia won't bloom in the heat; but some varieties, including Magadi Blue, Magadi Blue with White Eye, and Lucia Dark Blue, are heat tolerant. Blue lobelia can thrive in full sun, partial sun, or shade, and is notable for being easy to grow, just requiring more frequent watering in hot weather.

Blue Lobelia is a Striking Addition to the Garden Majesty

Seeking that ‘stand out’ plant that will make your visitor’s eyes pop? Look no further than Blue Lobelia, an annual whose flowers that are a truly vibrant, beautiful blue that blooms continuously throughout the summer but is easy to care for, and does well in the ground, containers or window boxes.

Start by sowing seeds or buy fully grown plants. Place them in either a sunny or partially sunny spot in the garden, add a little slow-release fertilizer, water well but don’t over water. This is not a plant that likes being over watered! They are about six to eight inches when you plant them but can spread to nearly twenty-four inches by mid-summer so you can trim them to about half height if desired.
Great news, you can even overwinter your plants by keeping them indoors in a sunny location. They will bloom all winter and be ready for re-location come spring. That’s two sets of plants for the price of one!

You can even start new plants by setting 4-inch stem cuttings in moist soil in a shaded spot until the new roots form. With minimal effort, your new Lobelias are ready to come spring.
