70-75 Days to maturity (from transplant). Solanum lycopersicum. Hamson DX 52 12 Tomato Seeds. Non-GMO, warm season annual, open-pollinated, heirloom, indeterminate, slicing tomato. Suitable for growing in garden plots, raised beds, and greenhouses. These powerhouse tomatoes are also considered semi-determinate in regions with longer growing seasons. Hamson Tomato crops, also referred to as Hamson DX-52-12 or DX 52-12, develop medium-sized 8-9 oz fruit with scarlet-red color with a round uniform shape. Their high quality sweetness with less acidic flavor provides a bright bite and is great for canning! In fact, this variety was first developed by Dr. Alvin Hamson in the cooler mountainous conditions at Utah State University! Hamson produced disease-resistant tomatoes with a firm texture that can adapt to fluctuating temperatures and higher elevations, as its origin is often mistaken for Colorado. ~10,000 seeds/oz.
