The most important info about our flower bulbs

Welcome to our online store for organic flower bulbs. Flower bulbs are a new chapter in our family business. For over 40 years we have been producing seeds of old vegetables, flowers and herbs in Switzerland. For a few years now, we have also wanted to offer organic flower bulbs to make gardens bloom as early as spring. When it comes to flower bulbs, all roads lead through the Netherlands. Quality, choice and innovation: the best varieties are produced in the Netherlands!​

For this reason, we set out to find an organic flower bulb producer with a philosophy similar to ours. With Natural Bulbs we found the ideal partner. The production is 100% organic, which is extremely rare in the world of flower bulbs. The bulbs are of excellent quality and a beautiful flowering period is guaranteed.

To ensure the same quality as our seeds, we planted all varieties in our trial garden. We wanted to find out whether the bulbs are suitable for our climate, whether they bloom beautifully and whether the plants are robust. The result was more than convincing! We chose our favorite varieties and decided to offer them on this website. Our online catalog includes detailed descriptions and planting tips to help you choose and care for your bulbs.
