Seeds 101: Seed Selection & Terminology


If the word “heirloom” doesn’t make you want to get your hands on some seeds I don’t know what will. Something passed down from generation to generation, person to person, how could it get better? Except maybe seeds that are “open-pollinated”? For me, it conjures up a dreamy vision of bees and an abundance of wildlife, flitting around the garden, flower to flower.

The long list of terms used to describe seeds inspires a sense of possibility and, at times, confusion. Here are some basics to help you choose the seeds right for you.


Open-pollinated seed varieties passed down over the years, generally dating back to World War II. However, some say 50 years ago or more. Seed companies have taken on the job of producing heirlooms as they’ve gained in popularity. These are seeds that have tried and true qualities and produce plants with the same characteristics as the parent plant. So you can harvest seeds from heirlooms at the end of the growing season to be grown the following season. It’s important to note that some varieties within the same group of plants can cross-pollinate, especially when planted close to one another, creating a new variety, like a zucchini and a pumpkin. (What would that be called? A zucchkin?) That sounds like a risk verging on a wonderful adventure.


Stick with the dreamy vision of bees and insects and add wind. Seeds produced by open-pollination create plants consistent or “true to type” (similar to the parent). This is amazing because it allows growers like ourselves to produce our own seed supply. But really, it’s a natural, ecological process and we glean the fringe benefits.


Hybrids are just that, the hybrid of two different varieties. The term “F1” is used to describe the first generation off-spring of the parent varieties, deliberately cross-pollinated plants chosen for specific qualities with the purpose of creating something new, generally to create a plant that has particular disease resistance, flavor, habits and vigor. This can be hugely helpful when growing your garden in challenging conditions or you’re looking for consistency. However, seeds grown from hybrids will not grow true to their parent plant but will have characteristics of the plants used to form the F1 generation. Sowing seeds produced by hybrids is not recommended.


Seeds produced by plants grown in a chemical free environment as regulated by the USDA National Organic Program. Chemicals include synthetic fertilizers and pesticides and doesn’t allow the use of genetic engineering. Organic seeds are the beginning of a healthy food supply and a robust environment and supports regionally grown seeds adapted to individual climates.


A Genetically Modified Organism (GMO) is an organism in which the genetic material of one species is artificially implanted into the DNA of another species. Combining genetics that do not naturally occur in nature. GMO seeds present a large number of problems, from unwanted cross-pollination and questionable health risks.

Pelleted Seeds

Seeds that are pelleted are coated with a clay-like material creating uniformity in size making the process of spreading seeds easier.

Treated Seeds

Seeds coated in a chemical, typically a fungicide, and often used in commercial agriculture. Organic practices don’t allow the use of treated seeds.


Cross-pollination is the process that occurs when the pollen from the anther (part of the stamen/the male part of a flower) of one plant is transferred to the stigma (part of the pistil/the female part of a flower) of a different plant of the same species.


When male and female flowers exist on the same plant (such as a tomato) and pollen moves from the anthers to the stigma of the same flower.


  1. Very interesting and informative post. Favorite line? ” For me, it conjures up a dreamy vision of bees and an abundance of wildlife, flitting around the garden, flower to flower.” Precisely!
