All about Dahlias

The dahlia is not only a stunning ornamental flower but also a name with meaning: it is a Greek girl’s name that literally means “flower.” Dahlias originally come from the highlands of Mexico, where they were cultivated by the Aztecs and valued for both their decorative blooms and edible tubers. In 1789, dahlias were introduced to Europe, and by 1810, cultivation began to develop actively in the Netherlands. Since then, dahlias have become one of the most popular summer and autumn flowers in gardens around the world.

Dahlias are incredibly versatile. They vary widely in height, from compact varieties of just 20 cm to giant types reaching up to 2 meters. Their flower forms are equally diverse, ranging from single and pompon to cactus-shaped and ball-shaped blooms, with an extensive spectrum of colors and patterns. Worldwide, there are estimated to be over 20,000 different dahlia varieties, making them suitable for many uses: borders, pots, cut flowers, or as striking focal points in any garden design.

Dahlias are also rewarding and relatively easy to care for. In favorable conditions, they can start blooming as early as mid-June and continue until the first frost. By regularly removing spent flowers, you encourage the plant to branch out and produce new blooms, giving you weeks of vibrant color and variety.

In addition to their garden appeal, dahlias are popular as cut flowers. Many varieties have sturdy stems and long-lasting blooms, making them perfect for bouquets and floral arrangements.

In short, dahlias combine beauty, versatility, and a long flowering season, making them a must-have for every garden lover.

De kunst van het veredelen

Achter iedere bijzondere dahlia schuilt een verhaal van geduld, vakmanschap en passie. Voor Jan is veredelen veel meer dan een beroep; het is een levenslange fascinatie. Al jarenlang legt hij zich toe op de kunst van het ontwikkelen van nieuwe dahlia's, steeds gedreven door dezelfde vraag: kan het nóg mooier, sterker en gezonder?

Veredeling begint met het zorgvuldig selecteren van ouderplanten met bijzondere eigenschappen. Met de hand worden bloemen gekruist in de hoop dat hun beste kenmerken samenkomen in een nieuwe generatie. Uit de zaden ontstaan vervolgens honderden unieke zaailingen, waarvan geen enkele hetzelfde is.

Daarna volgt een jarenlang proces van observeren, selecteren en beoordelen. Alleen de meest bijzondere planten mogen blijven. Dahlia's met uitzonderlijke kleuren, perfecte bloemvormen, sterke groei en een gezonde weerstand. Vaak duurt het vele jaren voordat een nieuwe variëteit uiteindelijk haar plaats verdient in het assortiment.

Jan beheerst deze bijzondere kunst als geen ander. Nog altijd is hij dagelijks bezig met het maken van nieuwe kruisingen en het beoordelen van zaailingen. Vanuit zijn passie blijft hij zoeken naar de allermooiste, meest gezonde en verrassende nieuwe soorten. Elke succesvolle introductie is het resultaat van jarenlange toewijding, ervaring en liefde voor de dahlia.

Wanneer u kiest voor dahlia's uit eigen veredeling, kiest u voor unieke variëteiten die met zorg, kennis en passie zijn ontwikkeld. Een levende collectie waarin vakmanschap en vernieuwing samenkomen, generatie na generatie.

Planting dahlias

Dahlias for garden, pots, or balcony

Dahlias are true all-rounders: they grow in almost any soil, as long as it drains well and doesn’t become too dry. Give them a sunny spot – a few hours of shade per day is no problem – and they will still bloom abundantly.

Lower-growing varieties are perfect for flower beds, pots, or large containers on your balcony or patio. Make sure the pots are big enough (around 10 liters) so the dahlias can absorb enough water and don’t dry out.

With the right location and a little care, dahlias will reward you with a lush, colorful display, both in your garden and on your terrace or balcony.

Caring for dahlias

Caring for Dahlias: Tips for healthy, blooming plants

Tall dahlias need support to prevent them from toppling over in strong winds. Use stakes or a plant frame to keep the stems upright and the flowers growing beautifully.

Want to keep your dahlias more compact? Start by pinching the young shoots early in the growing season. This encourages the plants to grow wider and ultimately produces a fuller bloom with more flowers.

It’s also important to regularly remove spent flowers. This stimulates the plant to continue branching out and producing new blooms, giving you a longer-lasting, colorful display while keeping your dahlias healthy and vigorous.

With these simple care tips, you can get the most out of your dahlias, in both height and bloom!

Overwintering Dahlias: Keep them healthy for next year

Dahlias are beautiful autumn bloomers, but unfortunately, they are not frost-hardy. To enjoy full, healthy flowers year after year, it’s important to store the tubers properly.

Before winter sets in, it’s time to lift the tubers from the ground. Cut back the stems to a few centimeters above the tuber and gently remove any soil or loose roots. This helps keep the tubers strong and healthy for the next growing season.

A key tip: label your tubers carefully. Note which varieties are tall and which are short, so you can plant them in the same spots next year. This not only helps with garden design but also ensures your dahlias thrive to their fullest potential.

Store the tubers in a cool, dry, frost-free place. This keeps them vital and ready to plant again in the spring. With proper care, you can enjoy the vibrant colors and versatility of your dahlias year after year, both in the garden and in bouquets.
