Like all the dahlia bulbs from my order, this one arrived quickly, well packaged, and of a very good size; the flowers will certainly be there this summer.

Description

The Dahlia Cactus 'Kennemerland' is a fairly old variety, introduced in 1973, but timeless and easy to combine in flower beds and bouquets. Its beautiful spiky flowers are a solid and vibrant yellow, a primary hue that will undoubtedly complement all other flowerings until late in the season. Its sunny flowering is abundant from July to the first frost, on a classic-sized plant that is easy to cultivate. 

 

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, much to our delight, gardens all over the world. They are perennial plants with fleshy tubers. Dahlias are classified according to the shape of their flowers. The Dahlia 'Kennemerland' is classified in the category of Cactus Dahlias. In this group, the flowers are large, and the colorful ligules that make them up are completely rolled up on themselves, giving them a spiky appearance. In this Kennemerland variety, the heads are 15 to 20cm (6 to 8in) in diameter and are composed of long, narrow, rolled-up petals with tapering tips. The plant will reach a minimum height of 90cm (35in) and a width of 50cm (20in), with a bushy and upright habit. The very branched stems are hollow and the leaves are opposite, pinnately compound, meaning they are divided into 3 or 5 leaflets, which have very denticulate lobes. The leaves and stems are bright green, a shade that enhances the color of the flowers.

 

To promote continuous flowering and extend the flowering period, be sure to remove faded flowers. Even better, regularly create attractive colorful bouquets by combining various varieties. The tall stature of this variety makes it suitable for the back of perennial plant beds, where it pairs well with white, deep purple, and purple. The flowering of Echinaceas is perfect when accompanied by Dahlias, as they bloom simultaneously, as well as perennial salvias, for example. Also consider grasses like foxtail barley or Pennisetum, which are very attractive in autumn.

 

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

Planting and care

The Dahlia 'Kennemerland' is easy to grow in all regions. For a generous flowering, it is good to follow a few simple rules: plant the tubers in a sunny location as soon as the last frost has passed; rich, fresh and well-drained soils are perfect. However, stagnant moisture would promote the rotting of the tubers. 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 six 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; it is 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 newspaper.

Store them away from freezing in a dry, cool, and dark place, such as a frost-free garage or an attic. In the southern regions, close to the coast, 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 ground with a layer of leaves or straw as protection. This tall Dahlia, with its hollow stems, does not withstand wind or heavy rain well. To counteract this disadvantage, you can stake it, but let's agree, it is not very aesthetic. On the other hand, by pinching the stems early or removing the axial flower buds, you will spread out the plant's habit, which will offer more resistance to bad weather. At the same time, you redirect the flow of sap to a single flower, which will become larger and stronger.

Consider staking this tall Dahlia if your region is regularly subjected to strong winds.
