Helping You Become a More Successful Gardener
Dahlia, Pinnate Dahlia
This entry has yet to be reviewed and approved by L2G editors.
Pinnate dahlia's simple green leaves on tall herbaceous stems are accented by beautiful, circular and daisy-like flowers in summer and fall. From the mild mountainous regions of Mexico southward to Colombia, it is a tender perennial with bulbous underground tubers. The nearly evergreen foliage is described as single, oval and pointed green leaves. When the weather is warm it will produce rounded, daisy-like flowers that are red, orange, yellow or white in color. It is advantageous to remove the old buds from spent flowers to encourage continued flowering.
Dahlias prefer well-drained, fertile soil and full to partial sun. The most beautiful flowers occur when nights are comfortably cool and days warm and sunny. Cultivars of pinnate dahlias are often grown from divisions of tuberous roots and cuttings to preserve their unique characteristics, or grown from seed to create new, interesting colored or shaped flower heads. All dahlias are cold sensitive and their tuberous roots should be lifted and overwintered in cool dry locations where winters are harsh. In hot, humid subtropical regions the dahlia is best grown in the late fall and winter with the start of the dry season.
