What the dahlia means
Dahlias are native to Mexico and Central America, where they were grown long before Spanish contact, and the dahlia has been Mexico's national flower since 1963. They reached Europe in the late 18th century and were named for the Swedish botanist Anders Dahl. Victorian flower dictionaries gave them mixed readings, from dignity and elegance to instability, perhaps because they were then a fashionable novelty. Today dahlias are often given to mark lasting commitment and creativity, though these are modern florist associations rather than old tradition.
Flower meanings come mostly from Victorian floriography, and they vary between books, eras, and cultures.

Keeping it fresh
Mid-summer to first frost; imported stems fill in at other times of year.
- 1 Dahlias barely open after cutting; choose blooms that are already nearly fully open.
- 2 Many growers dip fresh stem ends in hot water for about a minute to help them last.
- 3 Recut stems and change the water daily; dahlias are short-lived and cloud water quickly.
- 4 Keep in a cool spot out of direct sun.
