Heirloom, Organic Hybrid, GMO. What’s the Difference?
Redlands, Saturday, 19:31, sunny with rain on the way
Old Man Winter is approaching and from the looks of it, he is bringing lots of cold with him. Here in the nursery, winter has already arrived. This week, we saw our first frost. Thank goodness for the frost blankets we have been using to tuck in our plants at night. More and more of our daily operations are spent indoors, processing information from last season and pouring through seed choices for the upcoming growing season. This year, our season starts a bit earlier as we prepare for the Redlands Saturday Morning Farmers Market which is starting the first Saturday in January.
Growing only heirloom plants from seed is not as easy as you would think. No, I am not talking about the actual planting, germinating, thinning, transplanting, fertilizing, pruning, here. I am talking about the quest to find the most viable, reliable, reputable heirloom seed to begin with.
Heirloom. Open-Pollinated. Organic. Hybrid. GMO. These are what we all choose from when we are buying seed which ultimately becomes, with one exception, they type of plant we will grow our food from. Confused? Not a problem. Here’s what you need to know.
Heirloom. Heirloom plants are are grown from open-pollinated seed varieties that either pre-date or are unaltered by modern, man-made breeding methods. Heirlooms are known for their unique appearance, unrivaled flavor, historic fragrance and revered for their importance in maintaining genetic diversity.
Genetic Diversity- In a nutshell, the key to maintaining functional ecosystems [our gardens are mini-ecosystems] is having a wide array of living organisms with their original blueprint [DNA] in place. These plants possess the unique ability of helping other living organisms [fungi, bacteria, birds, bees, bugs...] cope with ever changing environmental changes due to their wide adaptability.
Open-Pollinated. This variety of seed/plant will grow and produce seed that is genetically “true to type” – meaning plants regrown from this plants seed will result in a plant exactly like the original. This is good, especially for growers and farmers for we can save seed from varieties of plants that do grow well in our areas to use for later plantings. The down side is that cross-pollination between same species of plants is common and thus we produce a hybrid. Best example of this – tomatoes. If you plant more than one type of open-pollinated tomato plants, chances pollen from one plant will travel to meet with pollen from the other and then the seed from both may carry traits from one another.
Hybrid This type of plant/seed comes from deliberate crossing of two distinct plants within the same species of plants [tomato with tomato] . The purpose behind this process is to combine the best traits of seperate varieties in to one plant. The benefit to a hybrid is that these varieties often have greater disease resistance and their produce can be more uniform in appearance. The down side is if you save the seed from a hybrid variety, you will not get the same plant again.
GMO stands for genetically modified organism. These varieties occur when we [man] deliberately takes genes from one species and artificially implants that gene into another species to create a seed/plant we would never find in nature. GMO crops are not allowed in organic farming and this is wise! Certain GMO crops have passed along their modified genes to other plants in the same species but we are uncertain of how to control this process.
Soap Box Moment re GMO: What really is the human health impact of GMO on our own health? That is the million dollar question. Genetically modifying your non-edible flower is one thing, maybe. Modifying a food you eat, that is another. We know that when we alter a plants genes in this manner, plants produce an extra protein which we ourselves may or may not have the enzymes present on our system to process that “foreign’ protein. In addition, there are some good studies that support the fact that fruits [produce from plants] from GMO’s contain less of the energy and vital proteins needed to support optimal health in young animals [http://www.owenfoundation.com/Health_Science/Pusztai/GM/GMHumanHealth.html] .
For the sake of protecting our families health, yours and our environment – we do not use GMO plants or seeds and never will.
Organic. Now this is perhaps the most interesting category. Many of us have a definition in place when it comes to the term “organic”. The term “organic” refers to only to the methods by which a product is grown. According to the USDA, “the principal guidelines for organic production are to use materials and practices that enhance the ecological balance of natural systems and that integrate the parts of the farming system into an ecological whole”. In addition,” organic food is produced without using most conventional pesticides; fertilizers made with synthetic ingredients or sewage sludge; bioengineering; or ionizing radiation.”
In a nutshell, this means that GMO seeds/plants are not used in organic nursery/farming production. This is good. Can a hybrid plant or seed be used? Yes! . Remember, organic refers to the methods by which they are grown. Interesting isn’t it?
This year, when the garden seed and plant catalogs arrive, we hope you will use this informatin to mindfully select what you will grow and ultimately eat. Please give mind to using only heirloom or open-pollinated varieties in your edible gardens. You will be glad you did for so many reasons – big and small.
Enjoy the day!
