Single Dahlia's Overview
Single Dahlia's produce blooms that have a single outer ring of florets - that occasionally overlap - around a central disc, that superficially resemble daisies. These florets can be either flat or slightly curved and judges of professional shows look to see if the overlaps are all in the same direction. The central disc can have up to three rows or very small bright-yellow or orange coloured flowers. The florets can be a whole range of colours or a mixture of two, making them a perfect addition to flower borders to provide late summer colour architectural interest to almost all garden styles. Regular watering and cutting flowers from this plant will improve performance. These plants may need staking; however, pinching out the growing tips in early summer will help it develop a bushier habit. The genus Dahlia contains around 20,000 cultivars are predominantly derived from D. pinnata and D. coccinea. Most Dahlias are divided into groups based on the form of their flower heads, from dwarf varieties to tall bushes and even tree specimens. This group of cultivars can have the abbreviation (Sin) or the number 1 included in the name.
