The
Seeds of Change catalog came in the mail yesterday and this is one of my favorite places to order from as they have a huge selection of organic and heirloom seeds.
When I speak with people who are looking to start their first vegetable garden, I usually suggest they go to their local nursery or big box store and start with some transplants. Transplants, having already been sprouted and partially grown, are in many cases easier to grow than by starting from seed.
The varieties at these locations, however, can be limited and certain varieties are either very simple to start from seed (peas, beans, squash) or simply don't make sense for the nursery to sell as transplants (carrots) and this is when seeds make sense.
When buying from a catalog or from a seed rack in the store, there are a number of terms used to describe the seeds. Many of these, like "partial shade" or "water often" are self explanatory, but here are a few that may not be obvious to everyone:
Zones: The U.S. Department of Agriculture divides North America into "
hardiness zones" which are geographic bands which are similar in temperature. If a plant or seeds list a range of zones, you need to be certain you live within that range or the range of the temperature will not allow the plant to flourish or even survive. This is particularly true if you are buying a big money item, like a fruit tree, which you expect to live for more than one season.
Determinate vs. Indeterminate: Most often seen with tomatoes. Determinate give fruit in one big burst while indeterminate give fruit the entire season. Determinate plants tend to be shorter and bushier while indeterminate tend to be more long and sprawling.
Annual vs. perennial: Annuals live for one season while perennials will come back year after year. Many herbs are perennials. Take care that you plant the perennials in a location where you want them to stay for years to come rather than right in the middle of an area that you expect to dig up at the end of the season. Some plants are labeled as "perennial grown as an annual" which means that in their native land they would last season after season, but in other regions they will last only one season. You may occasionally see the "biennial" which is something that will last for two seasons.
Seeds in the packet: The smallest size packet is usually the right choice for the home gardener. While 25 seeds or 1/8 ounce may seem like a small amount, chances are you only want a few plants of each variety anyway and you will more often than not end up with half a packet left over. The seed companies are pretty good about knowing what they doing in this regard.
Germination percentage: The percentage of the seeds in the pack expected to sprout. Seed companies have various controls in place to try and ensure good seed, but plant genetics, nature, and processing factors are not going to allow for 100% success. This is not usually significant for the home gardener and is more important for the farmer who might spend thousands of dollars on hundreds of pounds of seeds.
F1 or Hybrid: This plant is the result of crossing two other plants which hopefully results in the best characteristics of the parent plants. Seeds from these plants, however, will not produce the same results when sown the following year and are usually not good for saving.
Heirloom: These are seeds which have been saved and passed down over many years and will reliably produce similar characteristics year after year. These are the best types for seed saving.
Disease Resistant: This may often be followed by a number of letters such as PM or the name of the disease which the plant does well with such as "powdery mildew". This may not factor into your decision making process unless you happen to know you live in an area where a particular disease is common.
