75 Days. Dark Galaxy is a unique, mottled tomato, that looks like something from another planet. Meanwhile, here on earth it is a good tomato. I was very skeptical when I first grew these so I only grew two plants. Fruits were nice sweeter and earthy so I grew them again the following year. These will turn heads, in the garden or market. Perfect for garnish, sliced up in salads and for fresh eating.huge hit at our farmers market. Chefs are especially interested in them!
