Onions to Plant

Red Creole onions (Allium cepa) have a firm red bulb with a spicy flavor. These are the onions to grow if you want to make pickled onions. They are also delicious in salads, burgers, and sandwiches. 


Like yellow onions, they form big bulbs that can be stored longer term if they are kept dry and cool. 


Use Red Creole onions with fresh Roma Tomatoes and Genovese  Basil for bruschetta. 


Try these in fresh salsa, such as our recipe for Fresh Garden Salsa.


They are also a colorful and flavorful addition to grilled kabobs.

If you could only choose one onion for your garden, our Yellow Sweet Spanish Onion (Allium cepa) is the one. 


Yellow onions are the pillar of the all-important trio for so many cultures. This is the onion to put on the cutting board when the recipe calls for diced onion. 


The Yellow Sweet Spanish Onion grows large sweet yellow onions that can be 1 to 3 pounds each. 


This onion can be used in our Garden Fresh Salsa Recipe


Yellow Sweet Spanish onions are the perfect choice for carmelizing onions. Their flavor is transformed in the slow and long cooking process. Carmelized onions can be added to French onion soup, burgers, and dips.  

What is a bunching onion? 

Bunching onions are a variety of onion that is grown for green onions or scallions. We offer Heshiko Japanese Bunching Onion (Allium fistulosum). This variety doesn’t form a bulb and grows as a clump.


You can succession plant bunching onions to have a continuous crop of green onions all summer.
Bunching onions are also a great choice if you want to grow onions in pots or even indoors. 


Use bunching onions raw in dips, salads, and sandwiches. They are also delicious added on top of casseroles and stir-fries.

Like green onions, leeks don’t grow a bulb. And like other onions, they play an important part in flavoring. 


Leeks can be used in a bouquet garni - a bundle of herbs used to flavor soups and sauces. They have a delicate onion flavor and can be used fresh.


Like bulb onions, leeks have layers. The layers of green leaves turn to white at the roots. Usually, just the white and very lightest green parts are used in recipes calling for leeks. However, the tops can be used to season broths and stews and are removed before serving.


These giant leeks are delicious when gently steamed and sauteed. They can be part of a main dish or a side dish with chicken or fish.
