(9/26/12) -- We happen to like marigolds at the Dallas Arboretum. They are easy to grow, heat tolerant, and they come in wonderful shades of yellows, oranges and gold. They are especially appreciated in our garden during the late summer and fall months. Other than chrysanthemums, there just aren't many plants that give exceptional fall color.
Many years ago, Texas A&M Agriculture Extension extolled the value of "Mari-Mums" to everyone. Basically, they were telling us to plant African marigolds in the garden and just fib to our neighbors about them being mums. It really wasn't a bad idea. African marigolds planted in fall out-bloom any chrysanthemum we've ever tried. They have huge flowers of pumpkin orange and autumnal gold, and they are cheap!
So we wondered, if the big-flowered African marigolds were so great for us here in Texas for autumn color, which variety should we use? There are many to choose from. So we turned to the Dallas Arboretum Trial Gardens to sort out the best of the group.
