Indeterminate Heirloom Slicing Tomato. This heirloom from Mennonites in Wisconsin was first introduced to the Seed Savers Exchange by Thane H. Earle of Whitewater, WI. Tiffen has many similarities to the more famous Brandywine—potato-leaf foliage, pink skin, and rich old-fashioned tomato taste that has twice drawn raves at staff tastings. The large rough oblate beefsteak fruits (avg 13 oz) are a tad bigger and later than Brandywine. For a superb sandwich tomato or a fresh garden snack Tiffen is hard to top. Harden off and plant outside once night time temperatures are consistently above 50 degrees. Grows well in the ground or in a container. If you are planting in a container, tomatoes benefit from having at least a 5 gallon bucket sized container for each plant. They will also need some kind of plant cage or trellising to help keep them upright. 86 days to harvest.
