Seed Catalogs: Terms to Know Before You Buy - Part 1

(Updated: Feb. 1, 2021, 4:13 a.m.)

I don’t know about you, but I have a stack of seed and plant catalogs that started arriving around Thanksgiving.  I love to look at all the lovely photos and dream about and then plan what I will grow in my garden in the new year.  

Many folks who started gardening in 2020 and maybe even long time gardeners may be confused by some of the terms used in the catalogs.  In order to make sure you have the most success with what you grow, you need to understand those terms before you order and pay for seeds or plants.  

A Cultivar is a combination of the words ‘cultivated’ and ‘variety’ which means that a certain plant has been bred or selected for certain characteristics such as flower color, fruit size, or shelf life.  

Open-Pollinated plants are ones where the crop cross-pollinates itself & the offspring produced is nearly identical to the parent.  The seeds from these plants can be saved and you can expect an almost exact replica of the parent plant and fruit.

Hybrids are from seeds produced by a controlled cross-breeding of two distinct, open-pollinated cultivars. Seed harvested from this intentional cross-breeding are called F1 hybrids.  Hybrids can be vigorous, high producers, and may have been bred to give some disease resistance.  Seeds from the fruit of hybrid plants will not produce the same plant like the open-pollinated ones, so you must purchase new seed each year.

Heirlooms are seeds or plants that are open-pollinated cultivars that persist because their seed is saved and passed down from one generation to the next. They often have a colorful history and add interest to the garden and dinner table.  I had an Extension Master Gardener℠ volunteer in Virginia who grew a tomato every year that she called ‘Uncle Joe’s Tomato' that had been saved & passed down in her family for several generations. Often, Heirlooms are more susceptible in diseases and insects. 


Clones are plants that are replicas of the parent plan with the exact same genetic material as the parent.  They are produced by vegetative cuttings or through tissue culture.  Strawberries and blackberries are examples of plants that are cloned.
