Tomatoes may be the crown jewel of the summer garden, but growing them well means more than sunshine and water. It’s about choosing the best-tasting varieties and keeping away incompatible plants that can reduce yields or encourage disease. Fortunately, the research team at Johnny’s Selected Seeds has done the flavor-testing for us — and we’re here to share which tomatoes shine on the plate and which plants should steer clear of your vines.
Johnny’s Picks: The Best-Tasting Tomatoes
When it comes to flavor, the research team at Johnny’s doesn’t just test for yield or disease resistance. They conduct blind taste panels, examine texture, balance of sweetness and acidity, and chef-level appeal. Here are standout varieties worth growing in your Kris Hopkins Raised Gardens:
1. ‘Sun Gold’ (Cherry – Indeterminate)
Flavor: Bursting with tropical sweetness and tang.
Why Grow It: Often called “garden candy,” this orange cherry is a winner for kids and culinary types alike.
2. ‘Brandywine’ (Beefsteak – Indeterminate)
Flavor: Deep, rich, and almost smoky in its savory profile.
Why Grow It: A legendary heirloom tomato with old-world taste and stunning pink flesh.
3. ‘Pink Berkeley Tie Dye’ (Striped – Indeterminate)
Flavor: Complex, with balanced acidity and sweetness.
Why Grow It: Striking marbled color, rich texture, and bold flavor that chefs rave about.
4. ‘Citrine’ (Grape – Determinate)

5. ‘Mountain Magic’ (Campari-style – Indeterminate)
Flavor: Sweet, slightly floral, and resistant to cracking.
Why Grow It: Hybrid vigor with heirloom flavor — great for humid regions or disease-prone zones.
Tomato Trouble: Plants to Keep Away
Tomatoes are picky companions. Certain vegetables and herbs can compete for nutrients, harbor disease, or even release chemicals that stunt growth. This is known as allelopathy — and it’s more common than most gardeners think.

🌿 Better Companions for Tomatoes:
Instead, grow these nearby for better health and flavor:
Basil – Enhances tomato growth and repels pests
Borage – Attracts pollinators and deters tomato hornworms
Marigolds – Suppress nematodes and pests
Chives / Garlic – Repel aphids and whiteflies
Carrots / Lettuce – Low-growing and complementary
Garden Wisdom Sidebar: Determinate vs. Indeterminate
Not sure what kind of tomato you’re planting? The difference affects everything from how you stake your vines to how long you’ll harvest.

Pro Tip: If you want an early harvest with a quick finish, try determinates like ‘Citrine’ or ‘Roma’. For a season-long supply, stake up ‘Sun Gold’ or ‘Brandywine’ and prune them lightly for airflow.
