Have you ever wondered about how many beautiful flowers there are and which ones you can grow in your garden? There are perennials that flower year after year, biennials that last for two years and flower during the second, and annuals that only live for a year! Not to mention flowering trees and shrubs which definitely deserve a place in your growing scheme!

With so many wonderful names of flowers to choose from and learn about, choosing can seem like a difficult task! To make that a little easier, here is a list of flowering plants beginning with the letter C, plus a short description. 

#1 Calendula

Calendulas are lovely plants that are often referred to as pot marigolds, however, they aren’t marigolds at all! They are short-lived perennials that are native to Southern Europe and the Eastern Mediterranean and are usually grown as annuals.

They belong to the daisy family and have daisy-like flowers that bloom in large numbers. Their flowers are usually in bright shades of orange or yellow, but white and pink varieties can be found. Calendulas are known to deter insects, so are often planted in vegetable gardens alongside crops as a natural pest deterrent! 

#2 Calla Lily

Calla lilies, despite their name, are not actually true lilies. They are loved for their highly recognizable flowers which stand upright and are shaped like a trumpet! They come in many wonderful colors such as white, pink, red, yellow, orange, and purple, and can even be bi-colored. 

They like being in boggy areas so are perfect for planting around the edges of ponds or streams. Calla lilies are also good container plants and can be grown indoors too. Plant or position them in sunny areas, as although they can tolerate a little light shade, they won’t perform as well!

camellia bush
