Johnny Seed is solid.
Truly Medicinal for some more unusual items. She’s never sent me a bad packet.
Burpee is fine for seeds but I’d avoid any live plants or root starts from them.
Horseradish from Urban Farmer. Good stuff, reliable growth.
Wasabi from Oregon Wasabi. You know it’s genuine and the root starts are much easier to grow than seed.
True Leaf Market is wildly unreliable. I can get one perfect packet of seeds alongside a seed pack that is practically DOA. Bell peppers and cucumbers this last year, started in same conditions, had some mostly dead seed packets. 2 out of 3 bell pepper packets did not grow beyond 20%, while the third packet was at nearly 100%. 1g of pickle seeds at 10% germ with the second packet of pickle seeds at 80% germ. The Kitazawa seeds have been more reliable than the conventional seeds, with solid growth. The rest though? A roulette game.
