Photo and article by Donna Iverson A Facebook post appeared recently on my news feed that said Ohio had banned the Bradford pear tree. In case you are unfamiliar with this ornamental pear tree, it blooms in the spring with lots of white flowers. It has an attractive oval shape and is popular as both a landscape tree and a street tree. At least it has been for the last few decades. But now scientists are taking another look. While the tree is attractive, disease resistant, and grows fast, there is a downside. Seeds from the Bradford pear are spread by bird droppings and the offspring revert to the wild variety, called a callery pear. The wild pear is invasive, displacing native trees. So far it has been banned in South Carolina, Pennsylvania, Texas, New York and Ohio. In Kentucky, if you cut down a Bradford pear tree, they will give you a free native tree to replace it. The timber can be used for firewood or donated to woodworkers with whom it is popular. The story of how the Bradford pear came to America is a fascinating one. A native of China, the tree's seeds were first brought to America in 1908. They were collected by an Dutch emigrant named Frank Meyer. Meyer died at sea possibly by suicide, but his seed collection ended up in a test orchard in Oregon. In the 1950s, the Bradford pear became popular as a street tree and was prized for growing in the poorest soil, with few pests or diseases and needing little care or watering. By the 1980s, scientists were warning of the Branford pear’s invasive nature but the warnings appeared in scientific journals that were not widely read. It wasn’t until the last decade, that the tide turned against the Bradford pear and states, one by one, began banning its sale. Although sales of the Bradford pear have not been banned in Michigan, it might be wise to invest in native flowering spring trees like the dogwood, magnolia, cherry tree or redbud.

Photo and article by Donna Iverson Lettuce, crucifers, and oriental greens are the basic plants in a salad garden. Also some edible flowers like nasturtiums, violets, and pansies for garnishing the salad bowl, When it comes to leafy salad plants, choose from leaf and head lettuces, or other greens such as chicory, radicchio, endive, spinach, arugula and chard. Crucifers include kale and cabbage. Some orientalist salad greens to try include pak choi and muzuna. Early spring lettuce is the staple of my salad garden, mostly leaf lettuce and arugula. But each year, I like to try something new. So recently, I ordered collard green seeds from my favorite garden catalog. Directions said to plant any time after the last heavy frost until midsummer by pressing seeds into the ground to the depth of a fingernail. Then thin to about six inches apart once they sprout. Collard greens will tolerate both heat and cold, prefer full sun, and need regular watering. Plants emerge in about five to ten days. A member of the beet family, collards are grown for their leaves while beets are grown for their roots. Collards go by many names including Swiss chard, Chilean beet, perpetual spinach, and Roman kale. Leaf and stem colors include white, red and purple. In the kitchen, collard greens can be eaten raw in salads or cooked. Mature leaves can be tough so remove outer young leaves early if you plan to add to your salad. You can remove ribs from the leaves by folding the leaf in half and then cutting away the ribs. The ribs can then be cooked like asparagus. When cooking, add to stews and store fries. Collards keep about a week in the refrigerator. Collard greens are one of the easiest vegetables to grow and will continue producing all summer. Favorite varieties include Bright Lights, Fordhook Giant, and Lucullus. Try the variety Barese Chard for baby greens and harvest when they are about seven inches tall. The variety called Fordhook is an heirloom plant, dating back to the early twentieth century. |
