Certified excellence

Our saffron bulbs meet the highest standards, inspected multiple times each growing season by the Dutch Minister of Agriculture. This rigorous oversight ensures we can ship worldwide with unwavering quality.

That’s why the world’s top saffron suppliers trust Roco Saffron—not just for bulbs, but for reliability, purity, and a harvest that delivers. Because exceptional saffron starts with exceptional bulbs.

The importance of bulb size

For professional saffron cultivation, starting with healthy, large Crocus Sativus bulbs is essential. At Roco Saffron, we prioritize crop retainment, reserving our largest bulbs to sustain high-quality saffron production.

Bulb size varies yearly due to climate and growing conditions. Measured by circumference, we supply bulbs ranging from 8/9 cm to 9/10 cm to 10/+ cm, with 11/+ cm (Jumbo) being the largest available on the market.

Flowering yields

To boost first-year saffron yields, we’ve developed a climate-controlled temperature treatment that enhances flowering production. This method has consistently improved results, earning positive feedback from growers worldwide.

Moreover, bulb size directly impacts yield—the larger the bulb, the more flowers it produces, ensuring a stronger harvest from the start.

Reproduction of saffron bulbs

For a higher saffron yield, proper bulb reproduction is key. Since Crocus sativus is sterile and doesn’t grow from seeds, it reproduces through corms. The more small bulbs a mother bulb produces, the greater the next harvest.

Bulb quality varies by source—older, overused bulbs lose reproductive potential. That’s why Roco Saffron supplies only fresh, annually rotated bulbs, ensuring strong flowering and optimal reproduction. In peak conditions, a single mother bulb can produce up to 24 flowers!
