Copra
Copra yellow onions open with a bright, honeyed aroma and a crisp, juicy bite that turns sweet and mellow when warmed. The bulbs form a handsome, uniform globe with warm golden skins and tight, fine-textured layers—ideal for everyday use in fresh salads, savory roasts, and slow-simmered sauces, as well as classic pickling for tangy crunch.

Sowing Tips
Soil Temperature
Direct sow or transplant when soil at planting depth holds 45°F for reliable germination and early growth.
Expert Note
For the best storage bulbs, transplant into evenly fertile, weed-free beds when nights are consistently mild and keep watering steady through bulbing, then taper off as tops fall.
