Dahlia - Ball Columbus
Availability: Out of stock
The beautiful cultivar dahlia 'Ball Columbus' is famous for its perfectly spherical, vivid flowers. The blossoms are a striking accent to any garden because of their deep pink colour with faint violet undertones. As with other ball dahlias, 'Columbus' has neatly aligned petals that make a smooth, rounded shape that is eye-catching.
Â
This cultivar can be used as a conspicuous element in mixed flower pots or as a mid-border placement because it grows to a height of about 90–120 cm. It grows best in well-drained, fertile soil and likes full sun, which helps to bring out the colour of the blossoms.

Supplied as tubers, the best time to plant is in April and May. To plant them, dig a hole at least 20-30cm square and around 20-30cm deep for each one. Cover the base of the hole with 10cms of compost, or manure and give it a good dousing with a full watering can and then plant the dahlia at a depth of 15-20cms. You will need a stout stake, not just a bamboo cane, to support each plant and it is a good idea to knock this in first and then place the plant by its side. It will need to be lifted in winter - once the foliage dies back simply dig it up and store in a cool, frost free location.
