The Dahlia’s flowering period also contributes to its great popularity: they can be adding color to your garden from the end of July until the first frost – long after other flowers are spent.

Within the dahlia group as a whole, the Cactus dahlias have the most exceptional flowers. They have beautiful ‘spiny’ petals that are rolled up more than two-thirds of their length. Sometimes, the petals are straight from the base to the tip, but they can also curve inward or outward. The petals are often narrow and pointed, and some have deeply incised tips. These are the ones known as spider dahlias, and they make real eye-catchers!

The petals are not top-heavy because they contain little water. This means that dahlias remain standing up nice and straight even when it rains.
Tips!
- Dahlias are available in a wide range of different heights and colors, and they can be used for many purposes. They prefer a sunny location, and planting them is a breeze. Dahlias will grow almost anywhere: among your perennials, in pots, and in borders!
- Before planting, add some compost to the soil to amend it.
- Repeatedly removing spent flowers will ensure that new buds and flowers will appear and put on the best possible display.
- If you live in a cold area, and you want to save your tubers for next spring, you may dig them up before the first frost and store them over winter before replanting them next spring. Store them in boxes, covered with moistened sand in a cool, dark, frost-free place where the temperature remains between 45-50 °F (7-10°C).
- Height: 40 to 150 cm; Flower size: 4-12 in. wide (10 to 30 cm)
