Learn About Johnny's Selected Seeds for Home Gardening

Understanding Johnny's Selected Seeds and Their History

Johnny's Selected Seeds is a seed company based in Albion, Maine, that has been operating since 1973. The company specializes in providing vegetable, flower, and herb seeds to home gardeners and commercial growers. Founded by John Jeavons and Rob Johnston Jr., the company began with a focus on providing seeds suited to northern climates and short growing seasons. Over the past 50 years, Johnny's has grown into one of the largest independently-owned seed companies in North America, serving gardeners across diverse climate zones.

The company's approach centers on testing seeds in their own growing facilities before offering them to customers. This means that varieties sold through Johnny's have been evaluated for performance, disease resistance, and reliability in actual growing conditions. The company maintains trial gardens where staff members grow and observe thousands of plant varieties each year. This testing philosophy distinguishes Johnny's from some competitors that may not conduct their own field trials.

Johnny's Selected Seeds operates with a particular emphasis on open-pollinated and heirloom varieties alongside hybrid options. Open-pollinated varieties are plants that produce seeds that will grow into plants identical to their parents, allowing gardeners to save seeds year after year. Heirloom varieties are typically older cultivars with a history of being grown by home gardeners, often passed down through families. The company also offers hybrid varieties, which are created by crossing two different parent plants and often display improved vigor or disease resistance.

The company sources seeds from growers around the world while maintaining strict quality standards. Johnny's has developed relationships with seed producers in places like Europe, South America, and Asia, allowing them to offer varieties that may not be available through other domestic sources. All seeds are tested for germination rates before being packaged for sale.

Practical Takeaway: When selecting Johnny's seeds, understanding that each variety has been tested in real growing conditions can help you make informed choices about which plants are likely to perform well in your garden.

How to Navigate Johnny's Seed Catalog and Website

Johnny's Selected Seeds maintains both a printed catalog and a comprehensive website where gardeners can research and order seeds. The printed catalog arrives twice yearly and includes detailed descriptions, growing information, and photography for hundreds of varieties. The website version offers additional features including searchable databases, growing guides, and customer reviews for many seed varieties.

The website organization allows filtering by plant type, days to maturity, disease resistance, and other characteristics. For example, if you want to find tomato varieties that mature in 70 days or less and are resistant to late blight, you can use the search filters to narrow down options. Each seed listing includes information such as the number of seeds per packet, maturity dates, spacing requirements, and any special growing notes.

Days to maturity is one of the most important pieces of information in any seed catalog. This number tells you approximately how many days from transplanting (or direct seeding) until the plant produces harvestable fruit or vegetables. A tomato variety listed as "68 days to maturity" means it will take roughly 68 days from the time you transplant a seedling into the garden until you can harvest ripe fruit. This information helps gardeners select varieties that will mature before the first frost of the season.

Johnny's catalog descriptions often include resistance codes that indicate protection against specific diseases. For instance, "PM" stands for powdery mildew resistance, while "LB" indicates late blight resistance. These codes help gardeners select varieties suited to diseases common in their region or growing conditions. If you have experienced late blight in past tomato crops, selecting varieties with the "LB" code increases the likelihood of a successful harvest.

The website also includes growing guides for many crops. These guides provide information about starting seeds indoors versus direct seeding outdoors, optimal soil temperatures, spacing, watering needs, and harvesting tips. The guides are based on the company's testing and experience growing these plants in Maine, though you may need to adjust timing based on your own climate zone.

Practical Takeaway: Spend time reviewing the filters and search features on Johnny's website to find varieties that match your specific growing conditions, maturity timeline, and disease concerns in your area.

Selecting Varieties Based on Your Growing Zone and Climate

One of the most important factors in choosing seeds is understanding your USDA hardiness zone and growing season length. Johnny's catalog and website provide information to help with this selection. The USDA divides North America into zones based on average annual minimum winter temperatures. Zone 3 represents colder areas with winter temperatures reaching -40°F or lower, while Zone 10 includes areas where winter temperatures rarely drop below 30°F.

Growing season length refers to the number of frost-free days between the last spring frost and the first fall frost in your area. In Albion, Maine, where Johnny's is located, the growing season is approximately 120 days. If you live in a region with 90 frost-free days, you cannot grow varieties that require 120 days to maturity unless you start them indoors several weeks early. Johnny's catalog frequently highlights varieties suitable for short-season gardening, which is helpful information for northern gardeners.

The company offers a "Cool Season Collection" that includes vegetables and herbs that thrive in spring and fall conditions, such as lettuce, peas, spinach, and kale. These crops can tolerate frost and often taste better when grown in cooler temperatures. Johnny's also provides information about heat-tolerant varieties for gardeners in southern zones where summer temperatures regularly exceed 90°F. Heat-loving crops like okra, yard-long beans, and sweet potato varieties perform better in these conditions.

For gardeners in areas prone to specific climate challenges, Johnny's testing information can be particularly valuable. For example, if you live in a region with high humidity and frequent rainfall, powdery mildew and other fungal diseases are common problems. Selecting disease-resistant varieties reduces the need for fungicide applications and increases the likelihood of a successful harvest. Similarly, if your area experiences drought conditions, the company offers information about drought-tolerant varieties in various crop categories.

Johnny's also provides detailed information about seed starting timing. For example, tomatoes typically need to be started indoors 6-8 weeks before your last spring frost date. If your last frost date is May 15, you would start seeds indoors around March 20. Johnny's website and catalog include charts to help calculate appropriate planting dates based on your specific frost dates and the days to maturity for chosen varieties.

Practical Takeaway: Identify your USDA hardiness zone and the length of your growing season, then use this information along with Johnny's days-to-maturity data to select varieties that will mature before your first fall frost.

Understanding Seed Quality, Storage, and Germination Information

Johnny's Selected Seeds tests the germination rate of all seed lots before packaging them for sale. Germination rate is the percentage of seeds that will sprout under ideal conditions. For example, if a seed packet states a germination rate of 85%, you can expect approximately 85 out of 100 seeds to sprout if provided with appropriate temperature, moisture, and light conditions. This information helps gardeners determine how many seeds to plant to achieve desired spacing in the garden.

The information printed on seed packets includes a packed date that indicates when the seeds were packaged. Most vegetable seeds remain viable for multiple years when stored properly, though germination rates decline over time. Tomato seeds may remain viable for 4-6 years, while onion seeds typically remain viable for only 1-2 years. Lettuce, carrot, and many other vegetable seeds generally remain viable for 3-4 years under proper storage conditions.

Proper seed storage involves keeping seeds in a cool, dry location. The ideal storage temperature is between 40-50°F with humidity below 50%. Many gardeners store seeds in the refrigerator or freezer to extend their viability. Some gardeners place packets in airtight containers with packets of silica gel that absorb moisture. When stored this way, many seeds can remain viable longer than their typical lifespan. Seeds stored in warm, humid conditions deteriorate much more quickly.

Johnny's provides specific germination information and seed count information for different packet sizes. Some packets are labeled as "standard packets," while others are "bulk packets" containing more seeds. If you plan to save leftover seeds for future years, buying bulk packets when varieties are on sale can be economical. However, you should only purchase quantities you can store properly and use within the seed's viable
