Summer wouldn’t be summer without these lovely flowers, dahlias. Their beautiful flowers come in almost any color imaginable, from pale pastels to vibrant shades. They are also come in a range of flower shapes, from small tight balls to waterlily-like blooms the size of dinner plates. They are perfect for adding late summer color to gardens from July to October and look perfect in any style of garden. They also look especially great with summer blooming plants such as roses, cosmos, sunflowers, rose of Sharon, hibiscus, and bulbs such as iris, lilies, gladiolus, begonias, crocosmia, and freesia. Dahlias are also very brilliant and prolific cut flowers. The more you cut them, the more flowers they produce.

I have written a guide on how to grow these lovely flowers in your garden or yard!

About Dahlias

The dahlia originated in Mexico, where it was known to the Aztecs and recorded by Europeans in the late 16th century. Two centuries later the Spanish introduced it to Europe. It was, however, a quite different plant from the dahlia we know today.

One of the original species, Dahlia imperialis, had single lilac-colored or reddish flowers and grew in a tree-like form to a height of 6-18 feet. Smaller species were also discovered, including Dahlia coccinea, which had single red flowers. From several of these single-flowered species, the modem plants with their large, complex blooms were developed. The plant was called dahlia in honor of the eminent Swedish botanist Dr. Andreas Dahl.

I remember my aunt grew lots of dahlias back in the seventies. I was looking for a good guide to grow them myself now. This was what I was looking for! Lots of thanks! Jack
