This dahlia is very beautiful, unfortunately only two bulbs have bloomed, the others have probably rotted in the ground...

Description

Dahlia 'Obama' is a variety of fleshy decorative dahlia with mahogany flowers that blooms from July to October.

This perennial has tuberous swollen roots. Gathered in bundles, these tubers produce upright, hollow and branched stems, bearing compound, odd-pinnate leaves with rounded leaflets. Solid, fleshy 110cm (43in) tall flower stalks are topped with wide, flattened, rather incurved, 11cm (4in) in diameter, mahogany flowers.

Dahlia 'Obama' grows in rich, clay but healthy soil, worked deeply in warm and sunny conditions, sheltered from prevailing winds. It languishes in poor, sandy soils.

Dahlia 'Obama' is used in mixed flower beds with other varieties or for making bouquets.

Tips: When planting, consider the dimensions for the composition of your flower beds.

Planting and care

Dahlia 'Obama' is planted from mid-April to early May at a depth of 10 to 15cm (4 to 6in) and with a spacing of 60cm (24in). Always stake and loosely tie the young shoots. Apply slow-release compost or organic fertiliser during planting and liquid fertilizer monthly during the growing season. Water without wetting the foliage. There is no need to remove buds on this variety. Treat against aphids and slugs. Dig up the tubers before frost, cutting the stems to 15cm (6in) from the stump. Store them in darkness in a cool, well-ventilated place that is not too damp. Transplant in early May when frost is no longer a concern.
