It is superb, a feast for the eyes. It leans more towards orange than pink in my case.

Description

The decorative Dahlia 'Sunset Tropical', with its flowers in warm and coppery shades, will bring an original and refined touch to borders and homemade bouquets. Its flowers are medium-sized, double and slightly flattened, painted with a mix of pink, coppery orange and peach, illuminated by a lemon yellow center. The plant, which often doesn't require staking, forms a bushy clump of medium size and blooms late in the season, with abundant bright green foliage.

 

Dahlias belong to the large family of asteraceae, originally from the high plateaus of Mexico. Currently, the approximately 25,000 horticultural varieties obtained by humans have invaded, to our great pleasure, gardens worldwide. Dahlias are classified according to the shape of their flowers. 'Sunset Tropical', introduced in 2002, is classified in the category of decorative Dahlias. In this group, the colored ligules of the head are arranged regularly in a spiral, they can be bent towards the stem or curled, for example. In this variety, the heads are 12 to 15 cm (5 to 6in) in diameter and the ligules are wide, flattened and slightly folded towards the center. The yellow color at the base gradually changes to coppery orange with peach and cherry pink highlights over time. The ligules in the center retain a lemon yellow hue. Flowering takes place from July to October. The plant, with sturdy stems, will reach an average height of 90 cm (35in) to 1 m (3ft), and a width of 50 to 60 cm (20 to 24in). It has a bushy and upright habit, and is excellent for borders. The very branched stems are hollow and the opposite leaves are divided into 3 or 5 leaflets, which are finely toothed. The stems are sometimes tinged with purple.

 

To promote repeat flowering and extend the flowering period, be sure to remove faded flowers. Better yet, regularly create attractive colorful bouquets by combining various varieties. The stature of this 'Sunset Tropical' variety makes it suitable for the back of perennial borders, where it will blend well with red, yellow, brown and purple. The flowering of Sunflowers, Cosmos and Echinaceas is perfect as an accompaniment to Dahlias, as they occur simultaneously, as well as Asters, for example. Also consider the beautiful effect of grasses in autumn.

 

Stars of curated gardens, Dahlias are undoubtedly beautiful flowers, perfect in a flower bed, but they can also enhance a vegetable garden. In Mexico, this tuber was initially cultivated as a root vegetable for consumption. Its poor taste quickly assigned it the status of an ornamental plant. Since then, the interest in their beautiful exuberance has never waned.

Planting and care

The decorative Dahlia 'Sunset Tropical' is easy to grow in all regions. For abundant flowering, it is good to follow a few simple rules, plant the tubers in a sunny position as soon as the last frosts have passed, rich, fresh and well-drained soils are perfect. However, stagnant humidity would promote tuber rot. Do not hesitate to amend the soil with compost and sand if necessary. Work the soil deeply and enrich it, for example, with blood, fish and bone. Place your tuber and crumble the soil well to fill without air pockets. Your dahlia should be covered with about 6 cm (2in) of soil. At the end of planting, water once abundantly and then regularly renew this watering during the first 6 weeks to help with rooting. Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frosts cause the foliage to turn black, which is the time to dig them up. Carefully unearth 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 10 cm (4in). Spread your bulbs in a crate on a newspaper. Store them protected from frost in a dry, cool, and dark place, such as a frost-free garage or an attic. In milder regions, where there are only a few days of frost per year, it is possible to leave them in place. In this case, simply cover the soil with a layer of leaves or straw for protection.

This tall Dahlia, with its hollow stems, does not withstand wind or heavy rain well. To overcome this inconvenience, you can stake it, but let's agree, it is not very aesthetically pleasing. On the other hand, by pinching the stems early or removing the axial flower buds, you will spread out the habit of the plant, which will offer more resistance to bad weather. At the same time, you channel the flow of sap to a single flower, which will become larger and more robust.
