Beauty in the landscape

Gardeners from many countries have chosen to grace their homes, landscapes, and garden plots with dahlias, one of the longest blooming flowers in cultivation. No doubt, many reasons exist for their choice. While many grow dahlias solely as a decorative planting, others are more interested in artistic arrangement and cut flowers.

For decorative landscaping; they may use them as focal points in the home garden where they may select a plant that possesses a huge bloom, 12 inches or more in diameter, and thereby create a conversation piece. Still, others may concentrate on border plantings (12 inches or so in height) or mass planting of one variety for a special effect. Some find additional uses by using the dahlia for screens where the selected variety is crucial. The landscaping potential is great and the few examples above serve mainly to pique the imagination. In one home garden, the gardener has successfully groomed a small growing dahlia waterlily formation to cascade to the ground near his pool. The number of possibilities abounds including patio dahlias that are specially grown in ornamental troughs, pots, and tubs.

Softening the hardscape

Artistic arrangement adds another dimension to the dahlia. Flower arrangers vie for certain dahlia varieties that allow them to interpret for their thematic arrangement since the dahlia offers so much variation in form, size, and color. For special occasions, one or more baskets of dahlias will set off an event, whether it is for a church service, wedding, funeral, or community meeting. The cut flower comes into its own, though, for the gardener who desires to grow a few plants for house decoration. Whether for the professional or the amateur, the cut flower needs certain qualities, such as vigor, abundant bush habit, adequate stem length, many blooms from the beginning to the end of the season, a long vase life, and insect and disease resistance. Additionally, when the bloom is cut at an immature stage, it must successfully continue its development in water. Color is the dominant quality and gardeners’ preferences will vary greatly. For cutting purposes, small (4-6 inches in diameter), Miniature (2-4 inches in diameter), pompons, and open-centered dahlias function best as cut flowers. Still, it depends on the purpose for which that a gardener grows dahlias.
