Expression Yellow Storage Onion


Expression Yellow Storage Onion

(98 days) F-1 hybrid. The testimonials poured in when we threatened to drop this curiously named onion. Now that you have expressed yourselves, we’ll keep this nice big juicy sweetie around. “As large and flavorful as Candy with better disease resistance,” said Anne Nordell of Trout Run, Pa. “Wow, we had some that weighed almost 1½ lb apiece…I haven’t been able to eat any onions raw for years, but I was delighted to find that these did not bother my stomach at all,” chimed in customer Janine Welsby. Intermediate to long day-length (suitable for mid-Atlantic and northern areas), short to medium storage, decent heft (the large light brown globes average about 12 oz) and flavor. Bred by Bejo for high yields in rich clay loamy soils in the Northeast and PA. Has 1% red off-types. PR- tolerant.

Additional Information


Allium cepa

Days to maturity are from date of transplanting.

Culture: Start indoors in Feb. or March and transplant out in spring almost as soon as the ground can be worked. Set 4–6" apart in trenches in well-dug beds with generous quantities of organic matter. Avoid transplanting next to grass strips; slugs love to dine on tiny allium seedlings. Irrigate seedlings whenever the topsoil dries out.

Onions are day-length sensitive. Long-day types are for northern latitudes. The earlier they are set out, the more chance they have to make top growth while the days are lengthening. The more top growth, the greater the bulb size. After summer solstice they begin bulbing.

After half the onion tops fall, push over the remainder and harvest within a week. Field-cure in the sun about 10 days until dry, covering with a tarp in wet weather. Curing is essential for long storage. Hang sacks in a cool dry well-ventilated place, periodically removing sprouting or rotting bulbs. Onions survive light frosts. When it begins to warm up in spring, put your remaining storage onions in your refrigerator crisper. Most will keep without sprouting until your new crop is ready.

Minimum germination temperature 50°, optimum range 60-70°. We discourage the use of bottom heat because onions germinate poorly in temperatures above 70°.

We do not hold over hybrid onion seed because of precipitous decreases in germination. Onion seed is short-lived. Retest 1-year-old seed before using. Discard anything older.
