Dahlia Plant Features
Available in an almost unlimited selection of shapes, sizes, and colors, dahlias are a must-have plant for your garden. These versatile annuals work well in a wide variety of situations, from border edges to pots and planters. Dwarf types grow just 8 to 12 inches tall, while standard-sized dahlia varieties can produce dinner-plate sized flowers on 6-foot-tall plants. Flower colors include peach, red, lavender, white, yellow, orange, pink, and bi-color. Flower shapes vary from tiny pom poms to gigantic, corsage-worthy blooms. In frost-free regions, dahlias are tender perennials, but in most part of the country, dahlias are treated as annual bulbs that you can dig and save over the winter. Hardy from zones 7-11.

Dahlia Growing Instructions
Dahlias are sun worshippers. Plant them where they receive at least 6 to 8 hours of direct sunlight a day. They prefer a rich, slightly moist soil, but can tolerate drought if rainfall or irrigation is scarce. Tall dahlia varieties require staking to keep them from toppling during storms. Remove the flowers as they fade to encourage more bloom. Dahlia flowers are excellent for fresh bouquets.
Dahlia is not intended for human or animal consumption.
In the North, dahlias can be dug and saved over the winter. After the first frost blackens the foliage, dig the plants and wash away all the excess soil from the tuberous roots. Also, clip away the foliage. Then, plunge the tubers into slightly moist peat moss or sawdust and store in a cool, dark place over the winter. Check the roots during the winter and if they show signs of shriveling, sprinkle them with a tiny bit of water.
