Best Boxwood Shrubs For Maryland
Boxwoods have been a mainstay of the American Landscape for hundreds of years. Boxwoods were one of the very first plants the colonists planted and cultivated. Many plants were brought here by immigrants from their home countries. Many of our country’s founders planted boxwoods on their estates.
There are four types of boxwoods commonly available to today’s gardeners. American Boxwoods, English Boxwoods, Korean Boxwoods, and Japanese Boxwoods. There are many cultivars created by crossing the various species.
Boxwood is one of the easier plants to grow and care for, and it makes perfect plants for new gardeners because of its easygoing nature. Maryland’s climate provides one of the best climates for Boxwoods. We can grow a wide variety of the boxwood family in our gardens.
The green leaves of boxwoods are often seen adorning wreaths and other decorations during the holiday season. Boxwoods are very versatile when it comes to their usability in the garden. They are available in many sizes and shapes, including rounded, upright, pyramidal, and spreading. These evergreen shrubs can be trimmed into decorative topiaries, shaped into tall hedges or privacy barriers, or even planted alone as specimen plants.
Selecting A Location For Boxwood Shrubs
Boxwoods prefer a small amount of shade from the hot afternoon sun, although there are varieties that will thrive in full sun. They are very forgiving regarding soil types, provided the soil is well-drained and nutrient-rich. Boxwoods will not do well in soil that stays wet for extended periods after rain, so avoid “wet spots” when choosing a location.
Choosing The Best Boxwood For Your Garden
Boxwoods range in height from the diminutive Dwarf English Boxwood (Buxus sempervirens suffruticosa) at 1 foot tall to American Boxwood, which can reach up to 12 feet tall. This range of heights means that there is a boxwood to suit any garden size.
All boxwoods are evergreen; however, some are better at maintaining their dark green color through the winter. The Winter Gem Boxwood is known to turn a bronze color in the winter but is also known as the first variety to become green again in the spring. On the contrary, Wintergreen Boxwood stays green in the winter reliably.
If you like to have a variety of colors in your winter landscape, we recommend choosing a mix of varieties. There are many opinions on the bronze coloring of some boxwoods in the winter. Some gardeners prefer green types; while others are fond of the warm bronze tones some boxwoods take on.
