First attempt with dahlias in the garden, I chose this one and I am really delighted. Received a high-quality tuber with 2 or 3 emerging buds. The dahlia started growing in early May and developed quite quickly with beautiful foliage. And today, despite a few dried leaves due to the recent heat, it still looks very beautiful, produces a lot of flowers, and measures 1m35, which is even more than advertised, but it's perfect for me, I am even more delighted. The color of the flowers is superb!

Description

Dahlia 'Rocco' bears an abundance of small pink-purple pompoms with a mauve centre. They bloom on sturdy plants from July to October. They combine perfectly with a whole range of flowers, which is not always the case with large-flowered dahlias. Its cut flowers are beautiful in bouquets.

 

Dahlias belong to the Asteraceae family and are originally from the high plateaus of Mexico. There are currently thousands of horticultural varieties that have conquered gardens worldwide. 

'Rocco' will not exceed 90cm (35in) in height and 50cm (20in) in diameter. It is a pompom dahlia, a horticultural category defined by the shape of the flower. In this group, the heads are modest in size, but produced in abundance, and the tubular ligules form a perfectly spherical inflorescence that has a honeycomb-like structure. The flowers of 'Rocco' are slightly flattened and are about 5cm (2in) in diameter. The ligules are dark pink-purple, and those in the centre are more violet. The golden heart of the flower only appears late, just before fading. Flowering takes place from July to October. The habit is bushy and upright. The branched stems are hollow. Its leaves are opposite, pinnately divided into 3 or 5 toothed lobes. The leaves and stems are a medium green.

Remove faded flowers to encourage new blooms. You can use cut flowers to make colourful bouquets, combining them with other varieties. 

'Rocco' blends well with all summer and autumn flowers. In flower beds, plant it with shades of pink and purple, alongside echinaceas that bloom at the same time. It also works well with asters, large daisies, English roses, or even the stargazer lily. 

Dahlias are stars of borders and ornamental gardens, confidently accompanying the most beautiful flowers. However, they are also appreciated alongside vegetable plants. In Mexico, this tuberous plant was first cultivated as a root vegetable for consumption. Its poor taste qualities quickly saw it categorised as an ornamental plant. Since then, the interest in their beautiful exuberance has never waned.

Planting and care

It is easy to grow in all regions. Plant in spring as soon as the last frost has passed. For abundant flowering, plant the tubers in full sun in rich, moist but well-drained soil. Stagnant moisture causes tuber rot. Amend the soil with compost and sand, if necessary. Work the soil deeply and enrich it, for example, with crushed horn or dehydrated blood. Place your tuber and crumble the soil well to fill without air pockets. Cover with about 6cm (2in) of soil. At the end of planting, water once abundantly and then repeat this watering regularly during the first 6 weeks to help with rooting. 

Dahlias are sensitive to cold, so they need to be overwintered. Dig the tubers up when the first frost has blackened the foliage. Carefully remove the tubers. Remove as much soil as possible. Let the foliage dry so that the tubers can replenish their reserves. Then cut the stems to 10cm (4in). Spread your bulbs in a box lined with newspaper. Store them in a frost-free, dry, cool, and dark place, such as a garage or attic. In mild regions without frost, or those close to the coast, it is possible to leave them in place. In this case, simply cover the ground with a carpet of leaves or straw for protection.
