Roco Saffron Crocus sativus Bulbs

The 11/+ designation refers to the circumference of the bulb in centimeters. This is considered a jumbo size, which is significant because larger bulbs contain more stored energy, directly correlating to more robust flower production and a higher yield of saffron threads in your first harvest.

Crocus sativus bulbs should be planted in the fall. Getting them into the ground before the first hard frost allows the roots to establish themselves, ensuring the bulbs are ready to bloom when the season arrives.

No, you do not need to dig them up. These bulbs are perennial and will naturalize, meaning they will multiply and return on their own each season if left undisturbed in well-drained soil.

Well-drained soil is non-negotiable. Saffron bulbs are prone to rot if they sit in standing water, so if you have heavy clay soil, amend it with grit or compost to improve drainage before planting.

They thrive in full sun, which means they need at least six to eight hours of direct sunlight daily. While they can tolerate partial shade, you will see significantly fewer blooms and a lower harvest yield if they aren't placed in a sunny spot.
