Flower bulbs for
parks & gardens

Public parks and gardens are the place to go for city people anytime in spring to see thousands of tulips blooming in succession with vibrant color. Special cultivars of hyacinths, narcissus, tulips and more or wide spreads of flower bulb mixes are planted to ensure a constant color show from early spring to early summer. Our bulbs are planted in public gardens and parks all over the United States and Canada. We hold long term relationships with landscape designers, botanists and municipal buyers in all regions of the U.S.A. and Canada. Our experienced sales representatives can help you select the bulb cultivars, species or bulb mixtures that are best suited for your project.

Parks and Gardens

Top size, top quality

Ruigrok Flowerbulbs only deals in genuine bulbs of the highest quality and biggest in size. 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 and USDA and Canadian pre-inspection) prior to export. Many of our bulbs are grown at our own farms.

Our guarantee

We 100% guarantee our bulbs to be viable, healthy and free from injurious insects and disease upon receipt. All our bulbs are grown from cultivated stock. We stand by our product 100% and guarantee that they will arrive to you in optimal condition and will give you optimal growing results. Should this not be the case, we will replace them, no questions asked.
