Patterson Onion (F1 Hybrid ,104 days)



Long day

This is a replacement for the variety Copra which many gardeners loved and grew year after year but it is no longer available for us to offer.  Patterson hits the same marks of a great onion like Copra, except it is a bit larger and more uniform with copper colored skin and the same ability to store extremely well.    

150 seeds



Germination:  5-10 days

Germination Temperature:  Optimum soil temperatures 65-85 degrees F. Cooler soil temperatures increase germination time.

Seed Sowing Depth:  ¼” deep

Outside Sowing:  Early to mid-spring when soil temperature reaches at least 55 degrees F. Sow 1-3 seeds per inch, thin to 2-6” apart. The larger the bulb size the more space.

Starting Indoors:   8-10 weeks before last frost. Sow in flats/cells/pots ¼ ” deep, ¼-½ ”  apart. Provide 65-75 degrees F soil temperatures. Transplant seedlings out mid/late spring, 2-6” apart. Fertilize the seedlings every 7-10 days with a liquid or water soluble fertilizer (diluted to ¼ of suggested measurement).

How much does a packet plant:   15-20   foot single row  

Harvest:  Stop watering a week before harvesting. Pull out when tops fall over and skin develops. Cure them by drying them until the neck is dry, out of direct sunlight, in a warm area, and in single layer so air can circulate around them.

Tips:   Plant into fertile soil with lots of organic matter and adequate water, 1” per week for optimum growth.

Don't be afraid

I was very apprehensive. I planted Copra onions for years. I found the Pattersons to be bigger and to my surprise, sweeter and just generally better onions. We'll see how they keep over the winter. If they will keep like a Copra, it's game on.

Patterson Onion

very weak plants. In all my years of starting onions under lights inhouse, I've never had such an issue.

They are planted and under

They are planted and under lights in the basement. They came up very well and are growing nicely.

They are up and growing

They are up and growing in the green room. Will tell more when I eat my first one.


They keep well

I wanted to try Copra, but got Patterson instead because Copra was no longer stocked.. I start my onions inside and grow under lights, but got them started a little to late to get good big seedlings. Then when I should have planted them out in the garden; a tornado felled a huge tree on my garden. It was July before we could get that tree cut up and hauled away and by then the soil was packed hard. The onion seedlings still in their little container didn't look too hot any more either; but I chiseled holes in the garden dirt and set them in. They didn't do anything nut sit there and sulk for a month, but eventually they did make small onions which I dutifully harvested when frost came. It's mid January now and those little onions are firm and perfect. They taste delicious in whatever is cooked with them. I shall try them again and hope for better growing conditions. Garden tornadoes are not very common and that big tree that was shading the garden is gone.
