Heirloom Tomato
Purple Reign is a striking heirloom tomato that defies the common expectation of what a purple tomato should be. Developed by Dean Slater, this compact 3-foot plant produces dark purple beefsteak fruits in just 70-75 days, making it one of the faster-maturing purple varieties. Each tomato weighs around 6 to 12 ounces and arrives with a beautifully balanced flavor that works equally well sliced fresh, layered into sandwiches, or simmered into sauce. What sets Purple Reign apart is its tidy, determinate growth habit, unusual among purple heirlooms, which means you get a concentrated harvest from a plant that won't sprawl across your entire garden.

This is a genuinely compact purple tomato, a rare combination that makes it perfect for gardeners with limited space or those who prefer a manageable plant footprint. The fruits boast that distinctive deep purple color with a rich, balanced flavor that doesn't lean heavily toward one extreme. Its determinate nature means you'll get most of your harvest at once rather than a slow trickle through fall, which is ideal if you're planning to make sauce or preserve your crop. The fact that it matures in 70-75 days is a significant advantage in regions with shorter growing seasons.
Purple Reign excels as a slicing tomato for fresh eating, where its balanced flavor and substantial 6-12 ounce size make it ideal for sandwiches and salads. The fruit also works beautifully for sauce-making, giving you an interesting color variation and distinctive flavor in homemade tomato products. Because of its determinate growth habit and concentrated ripening, it's particularly suited to gardeners who want to process or preserve a larger batch at once rather than managing continuous pickings.
Start seeds indoors in a warm location, sowing them 1/8 inch deep. Seeds typically sprout in 7-14 days. Begin seeds indoors about 6-8 weeks before your last spring frost date, so transplants are ready to move outside once soil and air temperatures consistently reach 75°F or warmer.
Transplant seedlings outdoors after all danger of frost has passed and soil temperature reaches at least 60°F, ideally closer to 70°F. Space plants 24 inches apart to accommodate their mature width. Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days before planting.
Harvest Purple Reign tomatoes when they reach their full deep purple color and yield slightly to gentle pressure, typically 70-75 days after transplanting. Fruits should feel substantial in your hand, weighing in at 6-12 ounces. Pick tomatoes in the morning for best flavor, using a gentle twist or clean cut to avoid damaging the plant. Because of the determinate growth habit, you'll experience a concentrated harvest window rather than scattered ripening throughout the season.
Because Purple Reign is determinate, it requires minimal pruning compared to indeterminate varieties. Remove only damaged, diseased, or lower leaves that touch the soil, as this improves air circulation and reduces disease risk. Avoid aggressive pruning that would remove fruiting branches.

“Purple Reign was developed by Dean Slater, a breeder who recognized that purple tomatoes could be compact and manageable rather than sprawling vining monsters. This heirloom represents a deliberate step away from the typical indeterminate purple varieties that dominate seed catalogs, bringing the unique coloring and flavor of heritage purple tomatoes into a form that actually fits in home gardens. Slater's work demonstrates how heirloom breeding isn't always about preserving the old, sometimes it's about thoughtfully adapting treasured varieties to modern gardening realities.”
