Description

The 'Hapet Harmony' Decorative Dahlia with Small Flowers is a gorgeous tricolour dahlia, with warm yellow petals in the centre, marked with red-orange and tipped with white at the ends. This mix of colours catches the eye and gives it a very distinctive look. This fast-growing variety, with highly resistant colours, forms a medium to large-sized plant and provides abundant and prolonged flowering, from July until the frosts.

The Dahlias are tuberous plants from the large Asteraceae family, originally from the high plateaus of Mexico. Currently, the thousands of horticultural varieties obtained by humans have invaded, much to our delight, gardens worldwide. Dahlias are classified based on the shape of their flowers. 'Hapet Harmony' is classified in the Decorative Dahlias category, and in the sub-category of decorative dahlias with small flowers. In this group, the coloured ligules of the head are arranged regularly in a spiral, they can be curved towards the stem or even fringed, for example. In this variety, the heads measure 10 cm in diameter and their ligules are wide, oval, concave, flat to downward-curving. Flowering occurs from July to October-November. The plant will reach an average height of 1 m, and 40 cm in width, with a bushy and erect habit. The very branched stems are hollow and the leaves are opposite, pinnatisect, meaning they subdivide into 3 or 5 leaflets, which form very denticulate lobes. The leaves and stems are of a medium green colour.

To promote floral reblooming and extend the flowering period, make sure to deadhead the flowers. Even better, create alluring colourful bouquets by combining various varieties. Decorative Dahlias pair well with gauras and cleomes that lighten their generous silhouette. 'Hapet Harmony' flowers also make wonderful bouquets, with roses and grasses. The medium size of this variety makes it suitable for the centre of mixed borders, to structure an ensemble composed of bushy plants and lower-growing ones. The flowering of Echinaceas is perfect to accompany that of Dahlias, as they occur simultaneously, as well as that of perennial salvias, for example.

The star plants of cottage gardens, Dahlias are undoubtedly beautiful flowers, perfect in flowerbeds, but they can also enhance the vegetable garden. In Mexico, this tuberous plant was initially cultivated as a vegetable root for consumption. Its poor taste quickly relegated it to the status of an ornamental plant. Since then, the interest in their beautiful exuberance has never waned.

Planting and care

The Dahlia Hapet Harmony is easy to grow in all regions. For a generous flowering, it is good to follow a few simple rules, plant the tubers in full sun as soon as the last frosts have passed, rich, fresh and well-drained soils are perfect. However, stagnant moisture would promote tuber rot. Feel free to amend the soil with compost and sand if necessary. Work the soil deeply and enrich it with crushed horn or dehydrated blood for example. Place your tuber and crumble the soil well to fill without air pockets. Your dahlia should be covered with about 6 cm of soil. At the end of planting, water abundantly once and then renew this watering regularly during the first 6 weeks to help with rooting.

Dahlias are sensitive to cold, they need to be overwintered. In November, the first frosts blacken the foliage, it's time to pull them out. 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. Spread your bulbs in a crate on a newspaper. Store them in a frost-free, dry, cool, and dark place, such as a frost-free garage or attic for example. In southern regions, close to the coast, experiencing few frosty days per year, it is possible to leave them in place. In this case, simply cover the ground with a mat of leaves or straw for protection.

This tall Dahlia, with its hollow stems, is still sensitive to strong winds or heavy rains. To overcome this drawback, you can stake it, but let's agree, it's not very aesthetic. However, by pinching the stems early or removing the axillary flower buds, you will spread out the plant's habit which will offer more resistance to bad weather. At the same time, you channel the flow of sap to a single flower that will become larger and sturdier.
