Patterson Onion (F1 Hybrid, 104 Days)

Long day

Longest storage onion we offer. An outstanding variety that replaces the much-loved Copra. Extremely high yielding 3-3 ½ inch uniform bulbs. Copper-colored skins with firm flesh. One of our employees was still cooking with them in early May. Save some space in your garden to grow this one.                                  

150 seeds  

Please note that germination rates for alliums (onions/shallots/chives/leeks) decline rapidly. We strongly encourage you to purchase new seed each growing season.

Harvest- Stop watering a week before harvesting. Pull out when necks soften and start to fall over. Cure them in the sun for a few days then finish drying them out of direct sunlight, in a warm area, and in a single layer so air can circulate around them until the neck is dry. Store in a cool dark place with 35-40ºF temperatures and 65-70% humidity.

Tips- Needs fertile, well-drained soil. Amend with compost or apply organic granular fertilizer. Adequate water is very important for optimum growth, 1" per week.

patterson onions

Excellent! Pine tree is prompt and efficient. These onions, however, are not the best in my garden. They are not doing as well as Cortland, although I guess they were started later, as the earlier planting had poor germination. Cortland was no longer available when I reordered, so I got Patterson, despite the fact it had not done as well last year. They are far from ready to harvest at this point. Still trying to find a replacement for the excellent, long lasting copra.
