Nutrition and You...Nectarines! Bite into a perfectly ripe nectarine and you'll have juice flowing down your chin. There's nothing wrong with a little mess, especially on a hot summer day! Nectarines come in over 100 different varieties and are often confused with peaches. They are similar to the peach in both taste and looks, however, they lack that “peach fuzz” on their skin. Nectarines make an excellent addition to yogurt and salads, and they make a delicious, juicy snack on a hot summer day!

Zinnia: Not the Flower Grandma Grew! In the search for a durable, colorful annual flower able to handle the rigors of a typical Missouri summer, zinnia ranks high on the list of possibilities. Available in nearly every color of the rainbow, its heat and drought tolerance along with its low-maintenance nature make it a familiar sight in annual beds and borders. For decades, zinnia's major detraction had been its susceptibility to powdery mildew. Fortunately, plant breeders have made great strides in improving zinnia's ability to tolerate the troublesome disease while improving its desirable qualities. If you haven't grown zinnias recently, you are in for a pleasant surprise. In short, today's zinnia is not the flower grandma used to grow.
