Days to Maturity: 85

Grow delicious, long-storing, pungent yellow onions from these high-quality sets. These yellow onions are dense, round, heavy, and very spicy, with papery tan to brown wrappers and creamy skin. The mainstay onion of any kitchen, they are excellent for cooking.

Far and away the easiest and best way to grow your onions, "sets" are small bulbs that are planted in earliest spring and grow into full-sized onions by summer's end. They are simple to plant and cultivate, costing far less than plants and taking much less time and trouble than seeds. If you're trying to decide just how to grow your onions, bear in mind that most seasoned gardeners rely on sets.

This pack of 80 sets is enough to broadcast over the entire vegetable patch or other sunny area. Unlike most bulbs, onion sets do not have to be placed in the soil at any particular angle—there is no "right side up". So you can plant them beneath a half- to one-inch of soil at 4-inch intervals (in rows that are 1 to 2 feet apart), or you can broadcast them, cover them with a bit of soil, and thin the results later. Easy peasy!

Sow the sets about 4 weeks before the last spring frost date for your area; the plants are hardy to 20 degrees Fahrenheit or even less. To grow large, healthy onions, they need very well-worked, enriched soil, and should be fed and watered regularly throughout the growing process. Keep weeds to a minimum to retain soil moisture by mulching between the plants, if possible.

The onions are ready to harvest when the tops turn brown and begin to fall over. If you need to harvest a bit sooner, bend the tops over to encourage the finishing process. Carefully dig around the bulb (the top of which should be visible above the soil) and let them lie exposed for several days before removing. Dry and store in a cool, dark place. Yellow onions store well for months.

Onion Germination Information

Onion Hyssop Seed Germination How to Sow Onion:
  • Best sown outdoors in situ after all danger of frost is past in the spring and the soil is warm
  • In Zones 8 and warmer, seeds can be sown in the fall
  • Seeds can also be sown indoors at a temperature of 68-70°
  • Indoors and out, sow at a depth of 4 times the size of the seeds and expect germination in 10 days
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Onion:
Transplanting: Transplant when seedlings are about the girth of a pencil and as soon as the soil can be worked in the spring

Spacing: Thin or space 4 inches apart in rows spaced 12-18 inches apart

Soil: Site in full sun in a light, fertile, deeply tilled, rich soil

Additional Care: Water and feed regularly. The thinned seedlings can be used as a flavoring

Appearance and Use:

This 20 inch tall plant is grown for its edible, enlarged, bulbous, underground portion which may be white, red, or yellow in color. The narrow foliage is light green and is very strong smelling. Harvest the bulbs when the leaves begin to fall over and the bulbs are easily pulled from the ground. If there is resistance, the roots are still actively growing and the onion should not be harvested. Hasten maturity by removing the tops and look to be able to harvest the bulbs in a week. Eat them fresh or dry them for storage

Superior Germination Through Superior Science

Park's Superior Seeds Park Seed's humidity- and temperature-controlled seed storage vault Park Seed offers some of the highest-quality vegetable and flower seeds available in the industry, and there are a number of reasons for this.

First of all, we have humidity- and temperature-controlled storage, and we never treat any of our seeds with chemicals or pesticides. Nor do we ever sell GMO's (genetically modified seeds), so you always know the products you're buying from us are natural as well as safe for you and the environment.

Superior Standards - University Inspected

Testing seeds against minimum germination standards To make sure we are providing the best seed product possible and that our customers will get the highest number of seedlings from every packet, we conduct our own germination testing and have quality-control measures in every stage of our seed-handling operation. We hold ourselves to standards that are at or above federal and state standards, including testing specific crops more frequently than recommended by federal guidelines. And in order to maintain our organic certification, we welcome Clemson University to inspect us annually to make sure our organic seeds, which are stored and processed separately, are being handled properly.

Hand Packed By Experienced Technicians

Park Seed has been handling and packing vegetable and flower seeds for 145 years, a history that has given us a great understanding of how each variety should be cared for and maintained throughout every step of theprocess, from collection to shipping.

When packing our seeds, the majority are actually done by hand (with extreme care!), and we often over-pack them, so you're receiving more than the stated quantity.

The Park Seed Gold Standard

Park Seed's exclusive Fresh-Pak gold foil seed packets And many of our seeds are packed in our exclusive Fresh-Pak gold foil packets, which are lined to keep moisture out, so the seeds stay fresher for longer. We carefully pack very tiny or fragile seeds in crush-proof vials to ensure safe delivery to your home. Some of the small seeds are also offered as "pellets" (have a clay coating) to make sowing and growing easier.

When it comes to the kinds of seeds we offer, we are constantly seeking something new and provide many unique and hard-to-find varieties from all around the world. Our on-staff horticulturists are ready and available to share their expertise to help you with the success of these seeds, so you can grow a beautiful and productive garden!
Does Park sell GMO's or treated seeds?
GMO freeIt is important for our customers to know that Park Seed does not sell GMO or treated seed.

What are the differences between organic, heirloom, and hybrid seed?
Basically, organic seeds are seeds that are produced without the use and exposure to artificial/chemical fertilizers, insecticides, fungicides, herbicides, and other chemicals. They have to be grown, harvested, stored, and handled under very strict organic rules and procedures. All of our organic seeds are USDA 100% certified organic through Clemson University and the certificate has to be renewed yearly.

Heirloom Seeds are open-pollinated -- they are not hybrids. You can gather and save heirloom seed from year to year and they will grow true to type every year, so they can be passed down through generations. To be considered an heirloom, a variety would have to be at least from the 1940's and 3 generations old (many varieties are much older -- some 100 years or more!).

Hybrid seed are the product of cross-pollination between 2 different parent plants, resulting in a new plant/seed that is different from the parents. Unlike Heirloom seed, hybrid seed need to be re-purchased new every year (and not saved). They usually will not grow true to type if you save them, but will revert to one of the parents they were crossed with and most likely look/taste different in some way.

What are pelleted seeds? Why do you use them? How do I handle/sow them?
Pelleted pentas seedsExtremely small seed such as Petunias and Pentas are shipped as pelleted seed to make them easier to handle and sow. Pelleted seed are coated, usually with clay, to make them larger in size. After sowing, the coating will dissolve when wet and the seed will germinate. Pelleted seeds are shipped in vials placed inside seed packets, which protects them from being crushed. When sowing, be certain to use thoroughly moistened soil, to be sure that the clay coating absorbs enough moisture to dissolve. For sowing pelleted Petunia seeds, place the seeds directly on the soil surface and do not cover with soil, as light aids in the germination.

What is ideal temperature to germinate most seeds?
The ideal temperature to germinate most seeds is approximately 70 degrees F; give or take 1-2 degrees either way. This would be a good germination temperature for most flower and vegetable seeds and would be the most practical and feasible temperatures achieved for gardeners starting seeds in the home. You will notice for some seeds that it is recommended to use alternating day (warmer), night (cooler), temperatures, which is fine if one can provide such conditions. But most people are unable to provide those temperatures in a home setting, so just use the overall 70 degree F recommendation and the seeds should germinate well.

How long should grow lights be kept on per day and how close to the plants should the light be kept?
For germination and seedling/plant growth, you want to simulate the natural day-night cycles, and as a general rule, grow lights should be on 8-12 hours per day and off at night. You can vary this timing, as some seeds such as tomato, pepper, petunia, impatiens, and others, benefit from 14-17 hours of light per day (and the remainder of the 24 hour period in darkness). The most common grow lights used are fluorescent; using cool white, warm white, and wide-spectrum fluorescent tubes. These lights work well for germination and for growing plants up to a transplantable size. Fluorescent lights should be kept close though, 3-6 inches above the soil or the growing plants, adjusting the height as the plants grow.

How long will seeds keep in storage?
Park Seed stores seed in a special temperature- and humidity-controlled storage facility, which keeps seeds in excellent condition. Our seeds should be good for at least 1-2 years on average. Seed viability and storage time will vary depending on the seed item; some will keep a shorter time and some will keep longer. Seeds should be stored in a cool, dark, dry place. A basement will do (if not too humid), or a cool, dark room or closet. We recommend the best way to extend seed storage life is to store them in something air tight, such as a plastic zipper storage bag or canning jar, and place it in the refrigerator. This will extend the life of seeds for many years.

What is the best way to store seeds over a longer time period?
We recommend the best way to extend seed storage life is to store seeds in something air tight, such as a plastic zipper storage bag or canning jar, and place it in the refrigerator. This will extend the life of seeds for many years.

What depth should I sow various seeds?
When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed. When sowing seed indoors, the planting depth can be less, depending on the seed being sown, so it is always best to check specific directions. Here are some general guidelines concerning planting depth in relation to seed size: Tiny, dust-like seeds need to be sown on the surface of the growing medium or soil, uncovered, as they need light to germinate. The planting depth for small seed can be anywhere from barely covering, to 1/8-inch deep, to possibly 1/4-inch deep, depending on the recommendation. Medium seed should be planted at 1/4- to 1/2-inch deep, depending on the recommendation. Larger seeds can be planted 1-inch or deeper, depending on the recommendation.
