The Many Uses of Sumac

Vibrant Fall Foliage Are you drawn to bright scarlet leaves in autumn? You have probably admired sumac shrubs growing along the roadsides even if you didn’t know their name.  Sumac’s huge, compound leaves can grow to two feet long, made up of as many as 31 leaflets arranged along its colorful central stem.  They are deep green and glossy through much of the year, until they turn golden, orange, scarlet, or even deep purple from September until the leaves finally...

In Defense of Ivy

  Ivy:  Hero or Villain? English ivy, celebrated in hymns and carols, rich in history and tradition, may be among the most hated of ‘imported’ plants for some American gardeners.  Native plant enthusiasts may call ivy a ‘noxious weed.’  And now, thanks to a new state law, HB 1941, which will go into effect in Virginia in January of 2027, horticultural retailers will be required to label ivy as an invasive plant and suggest alternatives whenever it is sold directly...

The Fragrant Gardenia

  Fragrant Gardenia Flowers Fragrance often announces the shift in our seasons, alerting us to look more carefully for what has changed since the day before.  In June, a languid sweetness in the air calls our attention to the first flowers opening on the Gardenia shrub, a fixture in many Southeastern gardens, including residential gardens in coastal Virginia. Pristine, white and elegant, Gardenia flowers tend to fade all too quickly.  Their beauty is ephemeral as they fade first to beige...

Oh Deer!

  Fallen leaves carpet the ravine behind our home, broken only by thick green stems of bamboo, taller than most of our trees; a few young pawpaw and scarlet buckeye trees; and the thick trunks of century old beech trees.  There are also a few fallen, decaying trunks of trees lost to storms, but none of the undergrowth you might expect to find in a wild ravine bordering a small lake.  The soil is rich and deep.  Dappled sunlight illuminates...

Common Invasive Plants Every Master Gardener Should Know

  The question of invasive plants is an interesting one, in part because the list keeps growing.  Some of the plants on this list may surprise you because they are so commonly found in our local yards and landscapes.  A few plants have just been added to the list over the past year. While some, like stilt grass are noxious weeds, many of these ornamental plants are still available in the nursery trade.  Several are beloved by local butterflies and...

Options for Autumn Leaf Clean-up

  Leaves float on every strong breeze, covering our walks and driveway just hours after we last cleaned them.  The many different species of trees in our community almost guarantee that we will have a long season of managing fallen leaves and pine tags. Leaves may begin to fall in August or September, particularly when the weather is dry.  And some trees hold onto their leaves until the following spring.  So cleaning up fallen leaves is more of an ongoing...

Why Bother With Bulbs?

  Bins of papery brown bulbs appear in every garden center and big box store right after the back-to-school displays disappear for another autumn.  I love to study the photos of bright spring flowers on the bins, bags, and boxes of bulbs. They invite the ultimate impulse purchase.  “Where to plant them?” you may wonder.  No matter, you’ll find a spot. As trees turn gold and scarlet, we feel the chill in the air, and know that the long summer...

Can I Nibble the Fiddleheads?

Fiddleheads Perfect little green, tightly curled fiddleheads will soon push through the damp earth and begin to unfurl themselves into delicate fern fronds. They might look tasty, and you might wonder whether you can pluck one to nibble as you hike through the woods. Coastal Virginia hosts almost 30 native fern species, and fern-loving gardeners plant dozens more introduced species.  Quite honestly, unless you are a Pteridophile, or fern-o-phile, they probably look much the same.  You will find fiddleheads in...

Plant Knowledge

  “Power rests on the kind of knowledge one holds. What is the sense of knowing things that are useless?”  Dr. Carlos Castaneda     When a young graduate student in anthropology wanted to learn more about the medicinal uses of plants for his academic research in the early 1960s, so the legend goes, he sought out an old Mexican native, a brujero, known simply as don Juan, who lived in the Sonoran Desert.  Carlos asked to interview him about...

The Roots of a Virginia Christmas

  Our contemporary Christmas celebration is an amalgamation of many diverse strands of meaning, custom, and tradition.  The first English colonists who ventured to Virginia on behalf of the Virginia Company of London brought their traditions and customs with them.  And those customs were already an odd mix drawing bits from the ancient world of the Neolithic Celts, the Greeks and the Romans; all molded into the contemporary post-Reformation culture of urban England. Keep in mind that the earliest Virginia...
