About Dahlia's

All about the dahlia

The dahlia is a beautiful ornamental flower and a name with meaning: it is a Greek girl’s name that literally means ‘flower.’ Originally, the dahlia comes from the highlands of Mexico, where the plant was already cultivated and valued by the Aztecs for its decorative flowers and edible tubers. In 1789, dahlias were brought to Europe for the first time, and from 1810 cultivation began to actively develop in the Netherlands. Since then, the dahlia has grown into one of the most popular summer and autumn flowers in gardens worldwide.

Dahlias are extremely versatile. They vary greatly in height: from compact types of only 20 cm to giant varieties up to 2 meters tall. The flower shapes are also impressively diverse, ranging from single-flowered and pompon to cactus forms and balls, with a wide range of colors and patterns. Worldwide, there are an estimated more than 20,000 different variations, making dahlias suitable for all kinds of uses: borders, pots, cut flowers, or as a striking eye-catcher in garden design.

Dahlias are also grateful and relatively easy-to-care-for plants. Under favorable conditions, they bloom from mid-June and continue flowering until the first frost. By regularly removing spent flowers, you encourage the plant to branch out and produce new blooms. This way, you can enjoy an abundance of flowers in the most beautiful colors and shapes for weeks.

Besides their ornamental value, dahlias are also popular as cut flowers. Many varieties have sturdy stems and long-lasting blooms, making them ideal for bouquets and floral arrangements.

In short: the dahlia combines beauty, versatility, and long blooming, making it a must-have for every garden lover.

The art of refining

Behind every special dahlia lies a story of patience, craftsmanship, and passion. For Jan, breeding is much more than a profession; it is a lifelong fascination. For years, he has dedicated himself to the art of developing new dahlias, always driven by the same question: can it be even more beautiful, stronger, and healthier?

Breeding begins with carefully selecting parent plants with unique traits. Flowers are hand-crossed in the hope that their best characteristics will combine in a new generation. From the seeds, hundreds of unique seedlings emerge, none of which are the same.

Then follows a years-long process of observing, selecting, and evaluating. Only the most exceptional plants are allowed to remain. Dahlias with extraordinary colors, perfect flower shapes, strong growth, and healthy resistance. Often, it takes many years before a new variety finally earns its place in the collection.

Jan masters this special art like no other. He is still involved daily in making new crosses and evaluating seedlings. Driven by his passion, he continues to search for the most beautiful, healthiest, and most surprising new varieties. Every successful introduction is the result of years of dedication, experience, and love for the dahlia.

When you choose dahlias from our own breeding, you choose unique varieties developed with care, knowledge, and passion. A living collection where craftsmanship and innovation come together, generation after generation.

Planting dahlias

Dahlias in garden, pot, or balcony

Dahlias are true all-rounders: they grow in almost any soil, as long as it is well-drained and not too dry. Give them a spot in the sun. A few hours of shade per day is no problem. Even then, they will bloom abundantly.

Lower varieties are perfect for flower beds, window boxes, or large terrace pots on balconies or patios. Make sure the pots are large enough (about 10 liters) so the dahlias can absorb enough water and don’t dry out.

With the right spot and some care, dahlias will reward you with a lush bloom full of color, both in the garden and on your terrace or balcony.


Caring for dahlias

Caring for Dahlias: Tips for Healthy, Blooming Plants

Taller dahlias need support to prevent them from falling over in strong winds. Use stakes or a plant frame to keep the stems sturdy and help the flowers grow upright and beautiful.

Want to keep your dahlias more compact? Start by pinching during the growing season: cut back the shoots of young plants. This will encourage the plants to grow wider and eventually develop a richer bloom with many flowers.

It’s also important to regularly remove spent flowers. This stimulates the plant to keep branching out and producing new flowers. This way, you can enjoy a full, colorful bloom for longer, and your dahlia stays healthy and vital.

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

Storing dahlias

Overwintering Dahlias: How to Keep Them Healthy for Next Year

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

Before winter begins, it’s time to dig up the tubers. Cut the stems back to a few centimeters above the tuber and carefully remove any soil or loose roots. This keeps the tubers firm and healthy for the next growing season.

An important tip: label the tubers carefully. Note which varieties are tall and which are short, so you can plant them in the desired spot next year. This not only helps with a beautiful garden layout but also ensures the dahlias thrive to their fullest.

Then store the tubers in a cool, dry, and frost-free place. This keeps them vital and ready to be planted and bloom again next spring. With the right care, you can enjoy the vibrant colors and versatility of your dahlias year after year, both in the garden and in the vase.
