What Makes a Plant ‘Heritage’?

Age and History Requirements

The age requirement for heritage plants varies depending on who you ask, but most experts agree that these varieties should have been cultivated for at least 50 years to qualify. Some organizations set the bar even higher, considering only plants that have been grown since before 1940 or earlier as true heritage varieties. The Seed Savers Exchange, one of the leading authorities in heritage plant preservation, generally recognizes varieties that were introduced before 1950.

What’s fascinating about heritage plants is that many of them have been passed down through multiple generations of gardeners. Some varieties can trace their history back to the early colonial period in America, while others have roots in ancient civilizations. For example, certain tomato varieties still grown today were cultivated by Native American tribes centuries ago.

However, it’s important to note that age isn’t the only factor that makes a plant a heritage variety. The plant must also be open-pollinated, meaning it reproduces naturally and produces offspring identical to the parent plant. This characteristic ensures the variety maintains its unique traits generation after generation, preserving its historical significance and genetic diversity.

Open-Pollinated vs. Hybrid Varieties

One of the key distinctions in heritage plants lies in their genetic makeup and breeding history. Open-pollinated varieties are plants that reproduce naturally through wind, insects, or self-pollination, producing offspring that maintain the characteristics of their parent plants. These plants are true-to-type, meaning you can save and replant their seeds year after year with consistent results.

In contrast, hybrid varieties are created by deliberately crossing two different parent plants to achieve specific traits like disease resistance or higher yields. While hybrids can be excellent garden plants, their seeds won’t produce plants identical to the parents. This is why gardeners interested in preserving heritage varieties focus on open-pollinated plants.

Heritage plants are always open-pollinated, which makes them particularly valuable for seed saving and preservation. This natural breeding process has allowed these varieties to develop strong genetic diversity over generations, making them more resilient and adaptable to local growing conditions. Many gardeners appreciate this authenticity, as it connects them to traditional growing practices and helps maintain genetic diversity in our food supply.

Why Heritage Plants Need Our Protection

Genetic Diversity at Risk

Did you know that in the early 1900s, American farmers grew more than 7,000 varieties of apples? Today, you’ll find just a handful of commercial varieties in grocery stores. This dramatic decline in plant diversity isn’t limited to apples – it’s happening across all types of crops and plants worldwide.

As our food system has become more industrialized, we’ve increasingly relied on fewer varieties that are bred for uniformity, shipping durability, and high yields. While these traits are important for commercial agriculture, we’re losing countless unique varieties that offer different flavors, colors, growing characteristics, and natural resistance to pests and diseases.

This loss of genetic diversity makes our food supply more vulnerable. When we depend on just a few varieties, entire crops become susceptible to the same diseases or climate challenges. The Irish Potato Famine of the 1840s serves as a sobering reminder of what can happen when we lack crop diversity.

Heritage plants carry valuable genetic traits that took generations to develop – drought tolerance, frost resistance, and unique flavors that can’t be found in modern varieties. By preserving these plants in our gardens, we’re not just saving pieces of history; we’re maintaining a crucial genetic library that could help future generations adapt to changing growing conditions and ensure food security.

Cultural and Historical Value

Heritage plants carry stories that span generations, connecting us to our ancestors and their ways of life. These living artifacts offer glimpses into historical agricultural practices, traditional medicine, and cultural ceremonies that shaped different societies worldwide. Many of these plants were carefully selected and preserved by indigenous communities, who recognized their unique properties and significance in their daily lives.

Take, for example, the Cherokee Purple tomato, passed down through generations of Native American gardeners, or the Black Turtle bean, which tells the story of early American colonial farming. These and other local plant varieties aren’t just food sources – they’re living museums that preserve our cultural heritage.

In many communities, heritage plants play central roles in traditional celebrations, religious ceremonies, and healing practices. The sacred tobacco of Native American tribes, the ancient olive trees of Mediterranean cultures, and the traditional medicinal herbs of Asian societies all exemplify how these plants weave through the fabric of human civilization.

By growing heritage plants, gardeners become custodians of living history, helping preserve not just genetic diversity but also the cultural knowledge and traditions associated with these varieties. Each seed saved and planted helps ensure that future generations can experience and learn from these botanical time capsules, keeping ancient wisdom alive in modern gardens.

Starting Your Heritage Plant Collection

Finding Authentic Sources

Finding authentic heritage plant varieties requires careful research and connection with reputable sources. One of the most reliable ways to acquire genuine heritage plants is through seed banks and preservation organizations dedicated to maintaining these historic varieties. Organizations like Seed Savers Exchange and Native Seeds/SEARCH offer extensively documented collections with verified histories.

Local botanical gardens and historical farms often maintain heritage plant collections and frequently hold plant sales or seed-sharing events. These venues not only provide access to authentic varieties but also offer valuable guidance from experienced gardeners who understand the plants’ histories and growing requirements.

Heritage seed catalogs from established companies like Baker Creek Heirloom Seeds and Southern Exposure Seed Exchange specialize in old-time varieties and typically provide detailed documentation about each plant’s origin and history. When selecting a supplier, look for those who offer clear information about their seed sources and testing methods.

Connecting with local gardening groups and heritage plant societies can open doors to seed-swapping opportunities and provide access to varieties specific to your region. Many experienced gardeners in these communities maintain family heirlooms passed down through generations and are often willing to share both seeds and growing advice.

Before making any purchase, verify the seller’s reputation and ask questions about the plant’s history and documentation. Remember that genuine heritage varieties should have a traceable history of at least 50 years and be open-pollinated rather than hybrid varieties. Keep detailed records of where you source your plants, as this information becomes valuable if you plan to share or preserve these varieties in the future.

Essential Growing Tips

Growing heritage varieties requires attention to detail and patience, but the rewards are well worth the effort. Start with rich, well-draining soil amended with organic compost to provide the nutrients these time-tested plants need. Most heritage plants have adapted to thrive with minimal intervention, but they still appreciate proper care.

Water deeply but less frequently to encourage strong root development. Heritage plants typically have more extensive root systems than modern varieties, so they need space to spread out. Maintain consistent moisture without waterlogging the soil, and consider using mulch to retain moisture and suppress weeds.

Pay special attention to spacing when planting. Heritage varieties often grow larger than their modern counterparts, so give them plenty of room to reach their full potential. Most benefit from companion planting with other heritage varieties that have historically grown well together.

Save seeds from your strongest plants at the end of each growing season. Choose fruits and vegetables that show the classic characteristics of their variety, and allow them to fully mature before harvesting seeds. Store them in a cool, dry place in paper envelopes labeled with the variety name and year.

Avoid chemical fertilizers and pesticides when possible. Heritage plants developed their resilience through natural selection, and many have built-in resistance to local pests and diseases. Instead, focus on building healthy soil and encouraging beneficial insects to create a balanced garden ecosystem.

Monitor your plants regularly for signs of stress or disease, and remove any affected parts promptly to prevent spread. With proper care, these living pieces of history will reward you with abundant harvests and the satisfaction of preserving botanical heritage for future generations.

Seed Saving: The Key to Preservation

Seed saving is a time-honored tradition that forms the cornerstone of heritage plant preservation. By learning the art of collecting and storing seeds, you become part of a global community dedicated to protecting plant diversity for future generations. When propagating heritage plants, saving seeds is often the most reliable method to maintain their unique characteristics.

To begin your seed-saving journey, it’s essential to start with “true-to-type” plants, meaning they haven’t cross-pollinated with other varieties. Most self-pollinating plants like tomatoes, beans, and lettuce are perfect for beginners because their seeds will reliably produce plants identical to their parents.

Here’s a simple guide to successful seed saving:

1. Choose healthy, mature plants with desirable characteristics
2. Allow fruits to fully ripen on the plant
3. Clean the seeds thoroughly and dry them completely
4. Store in paper envelopes or glass jars in a cool, dark place

Remember to label your saved seeds with the variety name, date collected, and any special notes about the plant’s performance in your garden. Most seeds remain viable for 3-5 years when stored properly, though some can last much longer.

One of the most rewarding aspects of seed saving is sharing with other gardeners. Consider joining a seed exchange network or participating in local gardening clubs where you can swap heritage varieties with fellow enthusiasts. These communities often become valuable sources of knowledge and rare seeds that might not be available commercially.

For those new to seed saving, start with easy plants like peas, beans, or tomatoes. As you gain confidence, you can progress to more challenging varieties that require special techniques for seed collection and storage. Keep detailed records of your successes and challenges – this information becomes invaluable as your seed-saving practice grows.

By saving seeds from your heritage plants, you’re not just preserving genetic diversity; you’re also adapting these varieties to your local growing conditions. Over time, your saved seeds will develop into plants that are particularly well-suited to your specific climate and soil conditions, making them even more valuable for your garden and community.

As we’ve explored throughout this article, heritage plants are more than just beautiful additions to our gardens – they’re living links to our past and vital components of our future.
