Dwarf dahlias: what are the best varieties?
Stars of borders and pots
Contents
Their small size makes Dwarf Dahlias essential for pot planting on a balcony, on a sunny terrace, or grouped in threes or fives along the edge of a flowerbed mixed with other varieties and even for making bouquets. ‘Happy Single’, ‘Gallery’ Dahlias or Dwarf Cactus, which are the best? Discover all our tips for choosing your Dwarf Dahlia from our collection.
The great advantages of dwarf Dahlias
Small in size, Dwarf Dahlias are big on ease of cultivation! Low-maintenance, they require neither staking, nor pinching, nor pruning – simply remove the faded flowers – and offer better resistance to wind than their giant cousins, the giant dahlias. Moreover, they bloom for a long time, from summer until frost. They are radiant in the foreground of a flowerbed or as a border and sensational in pots on a sunny terrace or balcony.

A matter of size
In the large family of Dwarf Dahlias, there are small and… small: the Dwarf Dahlias, which do not exceed 40 cm in height, and the semi-dwarfs that reach a maximum of 80 cm. Both are used in pots, in window boxes, or grouped along the edges of flower beds. All very floriferous, they stand out from afar as they guarantee an endless season of flowers. They form compact bushes and offer an abundance of small or large flowers in a wide range of colours.
Among them are the ‘Gallery’ Dahlias, about 45 cm tall, the Dwarf Cactus Dahlias, ranging from 50 to 60 cm, and the ‘Happy Single’ Dahlias, which do not exceed 60 to 80 cm. Also essential are the 60 cm tall Collarette Dwarf Dahlias and the Anemone-flowered Dwarfs, which do not exceed 40 cm at ripeness.

And flowers!
The flowers of Dwarf Dahlias are replicas of the tall varieties. Reminiscent of cactus flowers, water lilies, or even anemones, their shape and diameter (approximately 6 to 12 cm) vary depending on the variety. All offer bouquets of cut flowers for arrangements. Among them, we can distinguish:
- Simple dwarf dahlias (Landscape): their flowers are single like the ‘Happy Single’ with vibrant colours and purple foliage.
- Double dwarf dahlias: with solid-coloured or variegated flowers featuring two rows of petals. This category includes the opulent and colourful ‘Gallery’ Dahlias.
- Dwarf Cactus: they offer an abundance of large flowers with elongated petals in a wide range of colours.
- Dwarf dahlias with a collar: their flowers, about ten centimetres in diameter, are adorned with a lovely collar.
- Dwarf dahlias with anemone flowers: a variety covered in small flowers with wide, flat petals and a frilled centre.
