For over 30 years I have discovered, rediscovered, planted and created from scratch many useful food plants. Instead of cultivar development I focused on the population rather than the individual. The result of that experimentation lead to populations of plants that are genetically diverse  that can be grown 'true' from seed in a wide variety of environmental conditions. The foundation stock seeds represent some of the most healthful and versatile  woody perennials and perennial vegetables that often require minimal care yet provide a high level of nutrition not found in cultivated plants. Each plant that we harvest seeds from is selected for its high yields, disease resistance as well as its ease of use as it finds its way to its culinary end.  The plants grown from our foundation plants can provide both a living population to breed cultivars from or to use as is and reproduced ad infinitum from seed  as a population. Reproduction by seed allows the population to adapt over time. This makes cultivar development or to use as a single 'strain' or land race a field of possibilities that can never become genetically stagnate.  This is the ECOS Oikos Tree Crops Foundation Seed Stock. Limited availability. Once seeds are sold out, there is no way to know if we will offer them again.  Above image from our farm: Precocious hazelnuts, Below Image from our farm: American Persimmons
