Onion, Franzisco (Organic)

Allium cepa. Yellow Storage. 105 days.

Long day yellow storage onion that consistently performs well in our trials. Reliably produces perfectly round 5” bulbs with tight wrappers perfect for extended storage. Franzisco is famous for its high yield potential and strong root systems that are resilient under many growing conditions including dry farming. Franzisco is a good companion to Fehmel-Stieg, and also came to us via Harold Frasier who worked as an onion breeder for the global commercial onion market.

For bulb onions, sow indoors in flats with good potting soil February through March. Transplant into the garden in April or May, when plants are at least the size of a No. 2 pencil lead. Space 6” in rows that are 1’ apart. Onions benefit from frequent watering and shallow cultivation. Stop irrigating in August. Harvest when stem has shriveled and tipped over.

Seed Saving

To save seed, replant at least 20 onions (to avoid inbreeding) in the second spring. Large, beautiful globe shaped flowers attract pollinators. Cut whole seed heads when they open and show the black seeds. Thresh gently and winnow to remove debris and hollow seeds.  Isolate from other Alliums of the same species by at least ½ mile.

    Amazing Onions!

    Where did you grow this variety? Oregon

    I purchased these seeds last spring to grow onions from seed for the first time and WOW! They are awesome! The seedlings grew quickly and produced beautiful large onions that have stored very well so far! I’m still enjoying the onions that I started over a year ago and harvested last summer!
    They are my new favorite – I purchased seeds again to grow this year! I would highly recommend!
    Grown in zone 8b Willamette Valley Oregon
