We have
deep roots

1880 Willem Ruigrok began growing fruits and vegetables in De Zilk, in the Netherlands in what would become the heart of today’s Dutch flower bulb district. At the same time, he also started a small flower bulb nursery.

Top quality,
top size bulbs

Ruigrok Flowerbulbs only deals in true to name bulbs of the highest quality and size. We believe in: “bigger is better”: Our tulips for instance are sized 12/+, our daffodils are 14/16’s or 12/14’s and our hyacinths are 16/17’s. Our bulbs go thru a rigorous inspection process (including MRI scanning, USA and Canadian pre-inspection) prior to export. Many of our bulbs are grown at our own farm.

We stand by our product 100% and guarantee that they will arrive in optimal condition and will give you optimal growing results. Should this not be the case, we will replace them, no questions asked.
