Colossal Chestnut Seedling
This hybrid of Japanese and European Chestnut, Colossal Chestnut Seedling is disease resistant and bears abundant crops of large, sweet nuts. Beautiful , large spreading nut trees, Chestnuts feature long, tropical looking, glossy green foliage and showy cascades of fragrant, yellow male catkins in mid-summer. In the fall you can harvest bountiful crops of sweet and nutritious nuts encased in unique, spiny, golden brown balls. Unique among nuts, Chestnuts are high in starch and are delicious roasted or boiled. If you do not eat your nuts shortly after harvest, it is best to refrigerate them in plastic bags to keep them from drying out. Chestnuts like well-drained soil, full to half day sun and can grow 25 ft. or more in height at maturity. They are hardy to minus 25 °F, USDA Zone 4 and usually begin bearing 2-4 years after planting. Plant two or more plants for cross-pollination.
