Trial garden managers from across the country share standout perennials and annuals that you can buy this year. Subscribe Photo courtesy of Smith Gardens Every plant trial is different. Each trial garden has different weather conditions, sunlight levels, water needs and other factors that make each location unique. That can make knowing which plants are best to grow at your local greenhouse or wholesaler a difficult question to answer. It’s also a tough question for you when deciding what plants to include in a design or where to place them in a customer’s landscape. Fortunately, trial gardens are here to help fill in the knowledge gap.
