Spectacular
Within the dahlia group as a whole, the Cactus dahlias have the most exceptional flowers. The have beautiful ‘spiny’ petals that are rolled up along 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 colours, 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.
