Buckwheat (Fagopyrum esculentum) A fast-growing annual pseudocereal maturing in just 70-90 days. Seeds germinate rapidly within 3-5 days at 70-80°F and remain viable for 2 years when stored cool and dry. Plant 1/2 inch deep with 4-6 inch spacing in zones 3-10. Buckwheat's shallow root system makes it ideal for poor soils, while its dense canopy effectively suppresses weeds. White flowers attract beneficial insects, particularly pollinators and predatory wasps. Disease resistant but frost sensitive. Special characteristics include phosphorus mobilization in soil, honeybee forage production, and gluten-free grain that can be harvested 30 days after flowering.
