2018 Southwest/West Floriculture Field Trials: Dallas Arboretum and Botanical Garden

The Dallas Arboretum and Botanical Garden has trialed more than 1,434,492 plants over the years. This year the gardens included new cultivars of Texas favorites such as Zinnias, Salvia, and Vinca, along with new veggies and hanging baskets. With the high temps that this garden experiences regularly, its a great place to see which new varieties love the heat and can survive long, hot summers.
